Reactive Trajectory Management System for Multi-rotor Micro Aerial Vehicles using On-Board Sensors and Processing

The aim of this project was to design a multirotor Micro Aerial Vehicle prototyping platform capable of semi-autonomous and autonomous flight in order to be able to develop and test a low cost on-board reactive obstacle avoidance system. While multirotor MAVs have become much easier to operate thanks to automated 3D position holding, GPS navigation and self-levelling, avoiding static and dynamic obstacles in the environment still relies on human reflexes and skill. The current system is a modular device acting as an interface between the human control inputs and the MAV's Flight Controller board. When an obstacle is detected, the device will modulate the user's controls (or simulate user corrective adjustments in autonomous mode) overriding them if necessary depending on the MAV's velocity and proximity.
