Magnetic-Field-Inspired Navigation for Quadcopter Robot in Unknown Environments [PDF]
2019 International Conference on Robotics and Automation (ICRA), 2019 In this paper, a magnetic-field-inspired robot navigation is used to navigate an under-actuated quad-copter towards the desired position amidst previously-unknown arbitrary-shaped convex obstacles. Taking inspiration from the phenomena of magnetic field interaction with charged particles observed in nature, the algorithm outperforms previous reactive ...
