Teach-Repeat-Replan: An Ultimate Solution to Autonomous Drone
A complete and robust system containing all components for UAV aggressive flight in complex environments. It is built upon on the classical robotics teach-and-repeat framework, which is widely adopted in infrastructure inspection, aerial transportation, and search-and-rescue. Our system can capture users’ intention of a flight mission, convert an arbitrarily jerky teaching trajectory to a guaranteed smooth and safe repeating trajectory, and generate safe local re-plans to avoid unmapped or moving obstacles on the flight.
