- 1. WHAT IS DRONE? • A drone is an unmanned aircraft. • Drones are more formally known as unmanned aerial vehicles (UAVs) or unmanned aircraft systems. • Essentially, a drone is a flying robot that can be remotely controlled or fly autonomously using software-controlled flight plans in its embedded systems, that work in conjunction with onboard sensors and a global positioning system (GPS). • UAVs were most often associated with the military. They were initially used for anti-aircraft target practice, intelligence gathering and, more controversially, as weapons platforms.
- 2. ALGORITHM • Understand the drone dynamics and perform tradeoff studies prior to building prototypes. • Tune parameters and models before uploading them to the drone • Create a virtual environment tailored to the test cases • Run multiple scenarios and test cases rapidly
- 3. METHODOLOGY • A simple drone has been designed linking four links with center body. Rotors and stators have been placed at the ends of each booms (links extending from center to propellers) while a block have been placed at the bottom as a platform for drone to lift and land. • Drones use rotors for propulsion and control. A rotor as a fan, because they work pretty much the same. Spinning blades push air down. Of course, all forces come in pairs, which mean that as the rotor pushes down on the air, the air pushes up on the rotor. This is the basic idea behind lift, which comes down to controlling the upward and downward force. The faster the rotors spin, the greater the lift, and vice-versa. • Now, a drone can do three things in the vertical plane: hover, climb, or descend. • To hover, the net thrust of the four rotors pushing the drone up must be equal to the gravitational force pulling it down. • Just increase the thrust (speed) of the four rotors so that there is a non-zero upward force that is greater than the weight. • After that, you could decrease the thrust a little bit—but there are now three forces on the drone: weight, thrust, and air drag. So, you will still need for the thrusters to be greater than for just a hover.

- 6. Military Drones Probably the oldest, most well-known and controversial use of drones is in the military. The British and U.S. militaries started using very basic forms of drones in the early 1940s to spy on the Axis powers. Today’s drones are much more advanced than the UAVs of yesteryear, equipped with thermal imaging, laser range finders and even tools to perform airstrikes. One of the most prominent military drones in use today is the MQ-9 Reaper. The aircraft measures 36 feet long, can fly 50,000 feet in the air undetected and is equipped with a combination of missiles and intelligence gathering tools.
- 7. Drones For Delivery • Delivery drones are typically autonomous UAVs used to transport food, packages or goods to your front doorstep. These flying vehicles are known as “last mile” delivery drones because they are used to make deliveries from stores or warehouses close by. Retailers and grocery chains all over the country are turning to drones as a more efficient delivery alternative, instead of relying on delivery drivers with inefficient trucks. These drones can carry 55 pounds of goods to your front door without you ever having to leave the house. Amazon, Walmart, Google, FedEx, UPS and many other big brands are all testing out different versions of delivery drones.
- 8. Drones For Emergency Rescue • Sometimes it’s not safe enough to send humans into a rescue situation, due to the scope or severity of the disaster. That’s where drones come in. In the case of a capsized boat or drowning individual, officials can throw an Autonomous Underwater Vehicle (AUV) into the water to assist in the rescue. If there’s an avalanche, drones are deployed to look for those caught in the snow. Aircraft maker, Kaman, has even developed a pilotless helicopter, called the K-MAX, designed to carry more than 6,000 pounds of cargo. The K-MAX has already been used in China and Australia to assist in fighting fires.
- 9. Drones in Agriculture • Drones have proven to be beneficial to the agriculture industry as well, presenting farmers with several ways to optimize their farms to maximize efficiency and reduce physical strain. Carrying out field surveys, seeding over fields, tracking livestock and estimating crop yield are all made easier through the use of UAVs while saving agriculture professionals valuable time.
