When the sensors detect motion on any of these axes, the motors counteract the motion to cancel it. A motor is placed on the 3 different axes around the camera. This is how drone footage is kept so still and stabilized. In other words, the drone solves the Pythagorean Theorem repeatedly to calculate the distance an object is from the drone. From this, the drone is able to calculate the distance it is from the object in front of it as the distance between the sensors is constant. These sensors calculate depth by identifying which image pixels from each sensor correspond to the same point. This drone has stereo vision sensors on the front and on the bottom, these sensors work in pairs, just like your eyes. This monitors the amount of power coming from the battery and distributes it to the drone’s ESCs and the fight controller. The ESCs are connected to the power distribution board (the battery) and the flight controller, as the ESCs receive signals from the flight controller it changes the amount of power given to each of the motors. These global positioning satellites give the drone the ability to understand where it is on Earth and maintain its position. From there, the drone calculates its geolocation based on the amount of time it took for the signals to arrive from the various satellites. These signals travel at the speed of light and are read by the GPS module on the drone. These satellites transmit information about its location to Earth’s surface. This is used in conjunction with the United States network consisting of 31 satellites.

It uses the Russian network known as GLONASS (Globalnaya Navigazionnaya Sputnikovaya Sistema) which is comprised of 24 satellites orbiting Earth. The global positioning satellite module uses two different global positioning systems to pinpoint the drone’s location. In this drone however, the drone knows its exact location from the GPS and the downward vision sensors, so even if wind is blowing it will stay in its exact place this is because the flight controller sends the proper instructions to the ESCs and intern the motors to compensate for the wind factor.

DRONE DEFINITION HOW TO
In the past or if you have a cheap drone it will just drift around as there are no sensors relaying information about the drone’s location and how to correct for these changes. An example of this is seen when a drone is hovering during windy conditions. The flight controller takes in inputs from the GPS module, compass, obstacle avoidance sensors, and the remote controller and processes it into information that is given out to the ESCs to control the motors. Each propeller rotates pushing the air down on the airfoil surface creating an area of lower pressure on top of the propeller and an area of higher pressure below it resulting in a difference of pressure thus pushing the drone up. Drone PropellersĪs drones (quadcopters) have two counter clockwise motors and clockwise motors, it also has two different propellers, one for each motor direction. This is why on helicopters there is a tail rotor to counteract the turning force from the single main rotor. So having an equal number of motors counteracting each other provides stability through equalizing the turning force. This is because of Newton’s Third Law which states that for every action there is an equal and opposite reaction. Drones (quadcopters) have two clockwise motors and two counter clockwise motors to equalize the turning force produced by the rotating propellers.
