Drone Collision Avoidance
Unmanned Aerial Vehicles (UAVs) are aircrafts that are either controlled remotely by a human from a ground station or by an on board computer. There are various types of UAVs such as fixed wing drones as well as quadcopters and hexacopters, all of which use rotating blades. Originally, drones were used in areas deemed too dangerous for humans with exclusive applications in the military sector, but recent enthusiasm has led to an expansion into commercial, scientific and recreational areas. The goal is to embellish a drone with a Collision Avoidance System (CAS). Such a system uses ultrasonic sensors to detect potential objects that are in the flight path of the aircraft. It then measures and displays the distance between hazards and the UAV. The drone also records live video footage, with its camera, which is sent to goggles or a display. The skills applied to the project include learning how to solder, wire, read blueprints, use mechanical tools as well as the methodology of assembling, building, and programming drones. To accomplish this, three sensors are placed strategically on the front, rear and bottom of the UAV. These sensors are connected to an Arduino (a single-board microcomputer) that is coded to send the data to the ground station. At the station, another microcomputer is connected to a radio receiver. This receiver collects specific information and displays them on an LCD screen.
