The current state of the art UAV obstacle avoidance requires an array of expensive time-of-flight sensors, LiDAR, or ultrasonic sensors. The new 60GHz RADAR allows for the same functionality but at a drastically lower cost. These RADAR chipsets are around $20 per sensor, and with a more than 100x improvement in measurable volume compared to time-of-flight sensors. These sensors are also solid-state and are smaller than your thumbnail. This capstone project aims to implement obstacle avoidance in drones with 60GHz RADAR and possibly demonstrate 3D autonomous mapping with this technology. This RADAR based system could be used for navigating dangerous areas full of smoke where individuals could not traverse, conduct safe travel in warehouses, or simply act as a safety measure for consumer drones.
