The term drone was originally used in Old English to refer to a male bee whose only work is to mate with the queen bee. Because of this, the drones have always been identified as idlers. While the worker bees are worrying about collecting nectar and defending the hive, the drones just idle around waiting to mate. Later in the 16th century, the term started being used to refer to lazy people. This was in relation to the behavior of the male bees. Also, at around this time the word began to be used as a verb to refer to a monotonous buzzing sound. So, how did the word begin to be used to refer to Unmanned Aerial Vehicles?
In 1883 during the Spanish American War, a kite was used to take the first aerial photograph. After this, the World War 1 led to the construction of radio controlled aircraft. However, they became ready after the war had ended. In the 1930s, the British DH 82B Queen Bee, a primitive Unmanned Aerial Vehicle, was developed by the British Royal Navy. It was in the year 1935 when U.S Adm. William H. Standley saw a demonstration by the British Royal Navy of the new aircraft that was remote controlled. Back in the U.S, Standley assigned a commander by the name Delmer Fahrney the job of developing a similar object for the U.S Navy. The Commander used the name ‘drone’ to refer to the aircraft in respect to the British Queen Bee. The term was fit since the drone could not function on its own and had to be controlled by someone on the ground. The British DH 82B Queen Bee could be landed to be used on another day and had the capability of reaching speeds as high as 160 km/h.
The Unmanned Aerial Vehicle was first used as a target by anti aircraft crews during training. Drones were later used as both training equipment’s for by anti aircraft teams and for missions involving aerial attacks at the time of the WWII technology rush. The United Kingdom, USA and Germany manufactured and used different types of Unmanned Aerial Vehicles. After the World War 1 had ended, jet engines were merged with the remote controlled aircrafts. A good example is the Teledyne Ryan Firebee, which was constructed in 1951. It was manufactured by Beechcraft. Other remote controlled aircrafts that had jet engines put into them include the Fairey Firefly, de Havilland Sea Vixen and the Gloster Meteor. A lot of money was spent on the modification of the aircrafts.
Modern Unmanned Aircraft Vehicles were developed in the US not so long ago. Their production began in the year 1959 when a highly classified Unmanned Aerial Vehicles program was started. The program was under the code name “Red Wagon.” The modern drones were first used in 1964 in the Vietnam War. More than three thousand Unmanned Aerial vehicles were flown during the war and five hundred and fifty four were lost. The United states later flew at around thirty four thousand surveillance flights with the use of AQM 34V Ryan Firebee. The surveillance flights, which were being controlled by operators, were launched from a host plane.
The UAV technology became more famous in the 1980s and 1990s. During this time it became cheaper and many countries could easily produce the drones. Machines that had higher capability of fighting were developed. MQ 1, AGM 114 Hellfire air to ground missile, became one of the initial unmanned combat aerial vehicles to be made. Drones have since been used for attack, surveillance and for transport purposes by the United States. The Unmanned aerial vehicles have without a doubt earned a top rank as some of the deadliest arsenal.
A drone is a quadcopter used for research purposes in various fields which include navigation, robotics, flight control and real-time systems. We know drones as weapons used in the war zones only. However, these miniature mechanical quadcopters have gained serious popularity in the recent years due to their complex performance activities.
What is Drone Racing?
Today drones are extensively used for both commercial and personal activities. Is drone racing the sport of the future? Yes, that’s what the scenario is portraying. In the recent years, drones have entered the field of sports and sports enthusiasts started considering these mechanically controlled air devices seriously for fun and entertainment.
More and more youngsters are getting attracted to the new game called drone racing. The competition involves participants to control the quadcopters and use a special head-mounted display to show live images captured by the device.
The game began as an amateur sport in Australia around two years ago where a player has to complete a set course in the minimum possible time to be a winner. Drone Racing will be using quadcopters called rotor cross where the rotor blades of the device are used to airlift.
Some gaming enthusiasts have taken the drones to the next level to race them against each other. It has become a matter of pride to see which drone has done better which further developed into drone racing. Today drone tournaments are being held in various countries across the world with huge money given away as the prize for the winning drone owner.
The prize money and adventurous gaming concept are attracting people of all ages to participate in the tournaments. Drones involved in the race tournaments are geared to accomplish the forward movement than upward thrust and has an ‘H’ configuration. The primary objective of this type of drone configuration is to provide high speed where the speed and maneuvering skills of the players are used to outpace the other participating drones.
Is Drone Racing the Sport of the Future?
Positively yes, it is predicted that drone racing will become familiar just like formula one racing. The existing drone models can see only what is there in the front of the drone with the help of the front camera which helps the user to give instructions to the device through radio-wave signals using manual inputs. However, the potential of a rotocross to become a Projected virtual reality sport by adding 360 degrees spherical cameras to the rotors which can make the game more exciting for participants and the audience.
The increase in the level of difficulty handling the drone at a higher altitude by the players enhances the complexity of the sport which will give an audience an adrenaline rush. Drone racing is going to be the most exciting games of the future as it involves both mental co-ordination of the player and high-end skills in drone making.
Is Drone racing the sport of the future? To an extent, yes. Although this kind of racing is exciting and entertaining, it is also quite expensive too, as it involves making of drones with the right material and motor to meet high-speed requirements of the sport and to avoid crashing during the race. Drone racing tournament requires massive investment, both from organizers and participants, unlike other sports which can be seen as the only reason for the delay in the sport flourishing.
Drones can offer farmers many great advantages in the field of growing crops. Today the use of drones in agriculture are becoming increasingly popular. Drones are in fact leading agriculture to becoming one of the most technologically advanced industries on Earth. Here are just a few great ways that drones are helping farmers today:
Drones are helping farmers contribute more sustainable ways of producing our food crops.
Drones can collect information from the distance for the farmer’s needs in predict crop yields, assessing crop health, monitoring and targeting water or irrigation and fertilizer distributions and applications.
Drones are helping our farmers save time and money combined.
Drones are helping farmers to increase crop quality, crop yields, as well as profits.
Drones can capture vivid aerial images to help farmers create maps for scouting their crops.
Drone images can be used by crop consultants and agronomists.
Drones can help farmers by allowing them to compare data and development of their crops across time.
Drones are helping to see things that cannot be seen on the traditional line-of-sight from the ground.
Drones Help Conserve
Drones can fly over fields to capture photos of crops. The information drones can provide a farmer is then transformed into maps showing if the crops are thriving or not. Drones are also helping to conserve resources. They can help farmers be more precise about irrigation. The data a drone can provide a farmer will help them make essential decisions like sacrificing entire crops after a storm.
Drones Helping to Feed A Growing World
Drones are now playing major roles in meeting the essential challenges of feeding a growing world population. Drone data can easily be transmitted to a web-based computer program for the farmer to view. This advanced sensor technology in agriculture is now in high demand by farmers located all across our nation.
Climate Changes and Agriculture
Climate changes are affecting the agricultural industry but advancements in agricultural technology are offering good benefits for the future. It has been predicted by experts that we must double global food production by 2050 in order to feed the population and drone technology can help us come really close to achieving this goal. Farmers are really the most capable people of effecting change, but they need help, especially the help of a drone which can offer all-in-one mapping platforms, high resolution images, and data.
Drones And Weed Control
Drones are helping farmers with weed control. Invasive weeds can destroy crops, and attract insects and pests. They are becoming an important agricultural tool just like the tractor. The use of drones in farming is called precision farming. They help in prevent blanket solutions for treating the whole field and instead they can help conserve. Drones can be used for creating weed infestation maps. Drones are helping farmers to examine the crop patterns along the side of images. Weedkiller to can be applied only to the specific areas where it is needed. This helps in reducing the use of these chemicals like weedkillers, pesticides, or insecticides. Aerial pictures can be taken from multiple views.
Drones Help Farmers Solve Problems From 8,000 Feet Above
Drones are able to communicate with areas of the field that need the most attention. Farmers occasionally run into problems with crops and drones can help them solve these problems. Research is still being conducted on the usefulness of drones serving the agricultural industry. Drones being used to help agriculture are industrial strength roto-copter drones that are durable and can withstand all types of climate conditions. Some of these drones being used to help farmers can collect images from altitudes as high as 8,000 feet or more. Drones are also helpful in livestock production.
Drones Fly Through Heavy Gusts
In agriculture, these drones are being used for collecting high-spatial and temporal-resolution images over wide ranges of regions in a very timely manner. When the farmer needs information quick and in a hurry, the drone can provide it promptly. A Farmer’s drone package deal comes available with three types of software that includes the drone, camera, and the brain that flies the craft. When connected to a computer, the computer can tell the drone what area to fly over the field. Some drones can even handle heavy gusts of 35 miles per hour and landings as well.
The FAA requires that drones and radio or unmanned controlled drones, planes, etc. that is piloted outdoors must be registered online or by paper with federal law and it must have a registration number marked on it. If you are the owner of a drone or unmanned aircraft weighing less than fifty-five pounds, then you may apply to have it registered online or you may choose to have your drone registered using the registration process by paper which is much slower. You will only need to have one for hobby or recreational purposes registered and then apply your unique registration number to your drone.
If you are a recreational drone pilot registrant, then you will only need to provide your name, address, and email address. The cost is $5 registration fee and this fee will cover all recreational drones owned by the drone owner. If you use your drone for work or business purposes, then each drone must be individually registered. The cost for each one will be $5. In addition to name, mailing address and email, you must also list the make, model, and serial number for each business drone you have.
Certificate of Registration
Once you have received your Certificate of Registration, then it must be carried with you when you are operating your drone. You can show your certificate electronically or on paper. If someone else is operating your drone, then they must present the certificate as well. You can give he certificate to the person who will be operating the drone or send them a copy by email.
If you are asked by any Federal, State, or local police enforcement officer, then you must have your certificate available to present to them. If you only plan to fly your drone indoors, then you do not need to have it registered. This is because the FAA does not have regulations for indoor drone use. If you plan to fly your drone in your own yard or even if it is just over your own property, then you will need to have your drone registered, especially if the drone weighs more than fifty-five pounds. Drones weighing more than fifty-five pounds can only be registered through the paper registration process.
If You Are Not A Citizen of U.S.
If you are no a citizen of the United States, then you will not be permitted for registering your drone here. You may only obtain recognition of ownership by following the the internet registration process. It is the Department of Transportation who requires recognition of ownership status here in the United States. Your drone should have already been registered in the country you are eligible to have it registered in and to obtain the complete operating authority from the Department of Transportation when you arrive here.
Cancelling Your Registration Online
If you are planning to sell or transfer your drone to someone else, then you must cancel your registration. You can do this online and the new owner should have it registered in their own name.
Failing To Register
If you fail to apply for drone registration, then you will be imposed high fines and penalties that can range in price from $27,500 to $250,000, or you may have to serve time in prison which could be up to three years.
The FAA is happy to help you with your questions or concerns about hobby or recreational drones as well as business or work drones. They may be contacted by telephone or online. They provide a toll-free number and it is (877) 396-4636. Drone pilots who experience an accident while operating their drone should report it to the FAA. You are allowed only 10 days to submit your accident report to the FAA. If you find a drone that has crashed in your yard, then you should contact your local police department. Reckless operation of a drone whether for recreation or business can result in you paying high civil fines or being subject to criminal action. This federal agency can help you better understand the rules of operating your drone safely.
The National Park Service has recently banned drones due to the noise and safety reasons. National parks today are considered to be a no drone zone. This rule for no drones allowed in these parks spans an area of over eighty-four million acres throughout the United States. The area also includes National Monuments, National Battlefields, historic sites, coastlines and seashores, rivers and walking, biking and hiking trails. Drones produce a negative impact for these parks. The most appropriate policy is still being considered. The FAA also have their say in the no drone zone.
Drones Disrupt People, Wildlife, and Birds
This is a rule that is sweeping every National Park in the U.S. Beaches and forests that are part of these parks are also included in the no drone fly area. Even a few individual parks have enacted the no drone ban due to park visitor safety and privacy concerns. Loud and noisy drones often interrupt visitors when view the peaceful and natural beauty of landscapes. Drones have also been known to cause disturbances to wildlife and birds. If you are caught flying a drone in a National Park, then high fines and penalties will be imposed.
Cost of Fines
Fines for flying drones in these banned areas can range from as little as fifty dollars to over a thousand dollars. The National Park Service intends to protect the environment from these flying robots. Precautions continue to escalate. The prohibited drone use in National Parks has even led to a drone’s pilot being tasered by a park ranger.
State Parks Are Creating Drone Bans Too
The National Park Service manages 58 National Parks located all across the United States. The drone ban is just a temporary ban for the launch of drones, operating drones and landing them until a permanent can can out in place. The temporary ban intends to stop the problem now until a long-term solution that is suitable for everyone takes place. Drones can be very invasive like causing damage to artifacts, the environment, and ecosystems. State parks are beginning to follow the footsteps of the National Park Service by creating their own drone bans.
Who May Fly Drones in National Parks
Drones can still be piloted in National Parks, but only by licensed professionals with permits for fire safety, search and rescue missions, and for science studies and research. Even responsible filmmakers are not allowed to fly their drones in any National Park until a permanent set of regulations are in place. For the next twelve to eighteen months, the NPS will evaluate the important effects of the unmanned aircraft or drones on visitors of the parks and natural park resources. This will help them to draft a permanent new rule and it will certainly be open for public comments.
Drones Produce Both Positive and Negative Impacts
If drones are used carefully and in the correct way, they can certainly contribute to a very positive and influential way of helping people to appreciate these breathtaking and beautiful parks from a long distance. It all has to do with the hands of the drone pilot. You can use the drone in a positive way that promotes the park or in a negative way that disrupts the park. The NPS is evaluating both the positive and the negative ways in order to determine the best laws for drones in these parks.
Drone Pilots Need Balance in Parks
There is an extreme need for balance for drone pilots in National Parks. Certain mishaps of drone usage can lead to changing appearances of the natural beauty these parks have to offer, like when a drone crashes into something. Sometimes the aircraft cannot be recovered and leads to litter. You must have experience to keep your drone under complete control. No, drones are not allowed in National Parks right now, but maybe someday soon they will be.
If you love flying drones, here is one question for you – can drones be hacked? While you might love flying your favourite drone, what if someone could control it without your permission? This possibility could mean that drones could be misused easily. So, can drones be hacked?
Aerospace engineering experts have studied and revealed that not much effort is needed to hijack a drone over the United States airspace and misuse to commit any kind of terrorism act or crime.
It has been proven that a drone costing more than $80,000 could be commandeered with the help of a Global Positioning System (GPS) technology and used for any purpose. Using unencrypted GPS information for navigating purposes, drones are extremely vulnerable to hacking and these include the drones used by most police agencies as well.
How is a drone hacked?
Being a type of malware, Maldrone is aimed specifically at UAVs or unmanned aerial vehicles which make use of Internet connections and hacks into drone. Drones are flying computers and are extremely susceptible to the hacking which happens in a smartphone or laptop. The technology for drone hacking can swipe the data collected by the machine previously or control it physically.
If the hacker is able to fake a GPS signal well, then he can convince an UAV into tracking the fake signal instead of the real one allowing him to control the vehicle completely from miles away.
If criminals can hack a military drone then it can obviously become quite dangerous but what will happen if hackers can also control civilian flying robots? Many drones are already being experimented with in sectors such as rescue and search organizations, crop monitoring, surveillance by police authorities and much more and is expected to be used by online retailers and postal services too.
Experts suggest that the Federal Aviation Administration should collaborate with United State’s Homeland Security Department to regulate drones. In the aviation sector, drones are considered to be a growth industry and many new companies are trying to enter this sector. If the hurdles that are being experienced in this sector can be taken care of, then more and more drones will be taken on missions to watch over humans. However, it is being highly speculated as to what kind of reconnaissance drones will be able to do and how they will affect civil liberties as this remains a major issue for discussion still.
Negative aspect of a drone
Several privacy advocates have started arguing that this will allow any individual to purchase a drone and spy on people right in their homes and backyards. This is why it is necessary to install such procedures that drone operators are unable to use the drone for personal purposes which they have not been licensed for. If this is not achieved soon, the American public is sure to be outraged and might come up with a negative reaction towards drones very soon.
Should you worry?
While the information might seem a bit frightful, do not worry. No drones have been hacked till now, and it is only the most complex drones that could be subjected to it. For all purposes, you do not have to worry about your drone being hacked, as normal drones cannot be.
Whether you are a civil quadcopter operator or merely a hobbyist, it important that you do not get into the wrong side of the law. This is because, most countries, led by the UK and US are moving fast to regulate the use of multirotors, in order to reduce cases of mischief like terrorism, hence safeguarding the rights of the citizens. The laws regulating the use of these crafts has been dubbed, The Drone code. With these laws, it means that quadcopters are legal, but under certain operations and restrictions.
The US ratified some legislations that target the use of multirotors in the late 2015. Amending of The Drone code was mainly because of the increased use of quadcopters in restricted airspaces like airports and the inability to distinguish the various degrees of autopilot assistance, hence attracting users with no experience in practical flying.
It is for these reason that governments like US, UK and Australia decided to address the legality on the use of quadcopters formally.
Different Types of Unmanned Craft Operations
Public Operations– This is where the craft is used for the government purpose. For example, the military and police are allowed to use these crafts in surveillance, spying on enemies’ territories in order to carry out an attack or monitoring the country’s airspace.
Civil Operations– This is where the quadcopters are used for commercial purposes. A case example is the Domicopter that delivers Domino’s pizza orders to customers’ doorsteps. In addition, news agencies are using quadcopters to cover live events and happening, hence promoting excellent journalism through relaying the correct information to the public.
Model Aircraft– This quadcopters are used for recreational purposes only. However, hobbyist are the greatest causalities of The Drone code, since most of them are likely to be mischievous when using these unmanned aircrafts.
Categories of Quadcopter Pilots
First Person Video– This is where a camera is attached to the quadcopter, where a video is taken and appears as a pilot is inside the craft, but in real sense, the pilot is only controlling the craft remotely.
Visual Line of Sight– This is literally keeping the quadcopter within your sight all the time. In order to fly the quadcopter effectively, the pilot should only fly the quadcopter in areas with no obstructions like tall trees and buildings and at a certain altitude. If this is contravened, you are likely to endanger the live of humans and property in the long run.
Guidelines Shaping the Use of Quadcopters
Aviation authorities in the US have and are crafting new rules to restrict the misuse of these multirotors in order to protect everybody’s interest. They include;
Keep the craft less than 400 feet above the ground level and stay clear of obstacles
Keep the craft within a visual range at all times, restricting the craft to a five mile radius.
Keep clear controlled airspaces for example airports or military barracks
Do not fly over populated areas like beaches, stadiums where a match is on or private homes without permission from relevant authorities.
The 21th century has seen the emerging of unmanned aircrafts that have taken over the air space. Slowly but steadily, it has now become a common phenomenon for the military, meteorologists, companies and hobbyists to fly them; and we can always spot them at times from a distance. These crafts are now being used to launch attacks on enemies’ territories, deliver products to customers’ doorsteps while also used as toys for hobbyists. However, there has been public outcries in some countries where drones have been used to spy on various different activities done in public, thus, undermining their citizens’ privacy. Despite all this, there is the question of when did drones become popular?
History of Drones
Many military forces in different parts of the world have been in the forefront in using drone attacks on enemies’ territories. The drone pilots, dubbed “cubicle warriors” are being recruited at a faster rate than the traditional jet pilots; who always risk their lives in combat. Early use of drones can be traced back to World War II, where unmanned jets were used in the Vietnam War. The Israeli Air Force has been accredited with winning many battles with enemies just by using electronic decoys, jammers and real time video reconnaissance.
In 1998, the US came up with Endurance Unmanned Crafts, which could stay up in the air for long. A notable achievement of these EUC, came when a craft named Laima, crossed the Atlantic Ocean in 26 hours. Civilian drones have also captured the attention of many aviation authorities in different countries. For example, the US estimates that by 2020, their will have more than 15,000 drones manning its airspace.
So Why Are Drones Popular?
1. Appealing Size and Portability
Unmanned craft technology has proven to be capable of capturing vital information from diverse angles; for example in filming movies or capturing live events. It is said that they may change the future of journalism in the near future.
2. Fall in Cost of Technology
Amazon and Dixons have attributed the growth of drone sales to their fairly low prices. Drones range from as low as £30 to £30000GBP depending on their intended use, battery power and accessories attached to them, for example a camera.
3. Safe and Quick in Capturing Live Events
Most news broadcasting stations are using drones to capture the latest live events as they happen. It is way cheaper to use a drone in capturing a forest fire, than risking the life of a photo journalist, while also cut on costs that come with hiring a helicopter that charges on hourly basis.
Regulations by the Aviation Authority
The popularity of these crafts have brought an outcry from the public since hobbyists and terrorist tend to use them for ill purposes, thus, forcing aviation authorities to impose regulations on the use of drones. There have been successful prosecutions over the misuse of drones in different countries. However, for developed economies like the UK, aviation regulators and civil stakeholders have been brought together in order to create an understanding on how the drones can be used to benefit everybody, hence reducing incidences of terrorism and misuse of drones.
Quadcopters are increasingly becoming popular since they are cool and fun to operate in order to make them fly. In addition, constant improvements are being made on a daily basis making them reliable machines for day to day use.
However, their use depends on their size hence serving different needs in the long run. Some of the interesting applications of a multirotor include;
1. Aviation Research
Multirotors are useful crafts in university settings since researchers use them to understand subjects like flight control theory and while performing complex flying techniques that contribute to improvement of day to day air navigation.
2. Military/ Law Enforcement
Quadcopters have been used by law enforcement agencies in surveillance of criminal activities hence busting out drug syndicates. Recently, Aeryon Labs, a Canadian lab created a quadcopter that helped in spying drug trafficking activities in Central America.
3. Search and Rescue Missions
Quadcopters are becoming popular as the go-to gadgets for search and rescue missions. When equipped with cameras, they give live pictures of the target area. In addition, they can be fitted with infra-red rays, to trace victims trapped under debris.
4. Deliver Online Shopping Orders
Amazon Prime Air intends to use quadcopters to deliver goods to the customer’s doorstep, confirms TechCrunch. However, Domicopter, Domino’s pizza delivery quadcopter, delivers pizza within a four mile radius in less than 10 minutes.
5. Transport People
Just as they can transport goods, they still can carry people around. E-volo, a German firm designed and tested a 16 propeller Volocopter that can fly with a pilot inside, for 20 minutes. However, improvements on battery technology, will see it carry more people and fly for long, in the future.
Quadcopters are being used in mining operation in different parts of the world. They have been deployed to handle jobs that are dangerous to humans. In addition, they have been used to inspect equipment, pitfall and entrances to the mining caves.
7. New and Sports
They are used to offer better views of field events unlike rail cameras since they follow athletes and film them. Quadcopters are also been sent to cover the latest news as they happen, for example, covering traffic jams as they are able to get closer to action and maneuver more quickly unlike humans.
8. Surveying and Construction
Quadcopters are used to provide details of the construction status from an aerial view, in the 3D modeling. It is also being used to monitor employees at a construction site, for example when making bridges, hence offer quality and efficient inspections.
9. Play Reality Games
Pilots have been known to play augmented reality games with these crafts in order to get a real perspective of the world. A good example of these games is Mission Helicopter, where a pilot is supposed to obstacles from their way and avoid blowing up their crafts.
The Future of Quadcopters
Solving problems relating to aerodynamics and gravity.
Capturing vital information relating to wildlife habitats hence promoting environmental conservation.
Delivery of medicine to patients in areas with adverse weather conditions.
It’s a great idea to make drones deliver packages. You do not have to worry about the delivery guy when you order online, and you could have the drone delivering right to your doorstep. However, there still remains many practical and logistical difficulties when trying to make drones deliver packages.
How Popular Is This Going to Be?
Big giants like Amazon are already supporting the idea of and providing evidence of the success of drones making delivery of packages. The debate, however, still on with people still skeptical about the whole process.
However, it does seem a lot likely that drones will replace many of the delivery guys in the near future. And recent studies and experiments point to the phenomenon – just like that of the driverless cars that will rule the roads soon.
How is it possible?
The first successful drone delivery was made in one of the States in US, and the development has made things more interesting. In March last year, a drone successfully delivered a package in one of the homes in Nevada.
It was the first autonomous delivery that has been made. For the delivery, a GPS system was established to create the route and there were supporting staff who observed the whole view. There did not arise any need for anyone to interfere and the drone went on to make a successful delivery.
Is it safe?
There is still a question regarding the use of unmanned flying objects. There have been no decisions made and the Government has not allowed the use of independent flying objects for delivery.
For drones to deliver packages, there has to be a lot of policy changes to bring something like this into action. The Federal Aviation Authority is working on the regulation that will govern the flying objects independently. There is also a strict regulation which states that if there will be drones covering the sky, they better be using different frequencies. It should be kept in mind that the technology should not compromise on safety. The drones need to use different frequencies so that they are not hijacked or misused.
What could be the problems?
Makers and technical heads who are keen on making it work have to think on a lot of things. The unmanned Drone as the delivery machine works solely on GPS.
So, what does the drone do when the routes are not updated? There is also a possibility that the connection is lost or the GPS systems unable to mark its way. In such cases, it will become a little difficult to find the locations and make a successful delivery to desired address.
A highly developed algorithm and systems would have to be introduced to make sure no major mishaps happen. With the use of camera this becomes a convenient job but then this does not make it an independent machine. The drones also are not capable yet of flying long distances, another major hurdle that researchers are working on now.
Despite the hiccups, the possibility of flying objects making delivery cannot be shooed away. It is likely that they will soon see the light of the day.
