Abstract:
We assembled a sensory unmanned aerial multicolor quad copter, which did not need any human intervention during its flight. Thus it flew autonomously using GPS coordinates. The quad copter was programmed in a way that, if it were to encounter an obstacle during its flight time, it avoided collision. The flight path was burned into the quad copter beforehand using the ground control station in the form of a mission plan. Obstacles were detected using sensors mainly ultrasonic sensors. On encountering an obstacle, the data from the sensors was fed to an on-board computer which was running an obstacle detection and collision avoidance algorithm specifically designed for the purpose. That algorithm formed the basis of the instructions issued by the on-board companion computer to the quad copter for avoiding collision with that obstacle.
