Recently, drones have been used in many different applications such as search and rescue operations, extinguishing fires, and environment mapping. As the number of moving drones increases in the sky, the collisions risk increases. In this paper, we present a system model, prototype, and preliminary evaluation for UAV obstacle avoidance. The obstacle avoidance system prototype uses ultrasonic sensors for obstacle detection, S-BUS communication protocol for drone control, and Savitzky-Golay filter for data smoothing.
