A dynamical system approach for detection and reaction to human guidance in physical human-robot interaction

Aude Billard, Mahdi Khoramshahi

A seamless interaction requires two robotic behaviors: the leader role where the robot rejects the external perturbations and focuses on the autonomous execution of the task, and the follower role where the robot ignores the task and complies with human in ...
