Autonomous quadrotor terrain-following with a laser rangefinder and gimbal system
Matthew Clark, Robert Christopher Roberts · 2017
This paper introduces a technique using a laser rangefinder sensor mounted on a movable gimbal system that enables an unmanned aerial vehicle (UAV) to maintain a specific height above changing terrain. The system and controller design are explained, and the performance of the laser rangefinder is compared with ultrasonic and GPS-based measurements.
