"Open Sesame!" - Adaptive Force/Velocity Control for Opening Unknown Doors.

Yiannis Karayiannidis, Christian Smith, and Danica Kragic


In this paper we consider the problem of humanrobot collaborative manipulation of an object, where the human is active in controlling the motion, and the robot is passively following the human's lead. Assuming that the human grasp of the object only allows for transfer of forces and not torques, there is a disambiguity as to wether the human desires translation or rotation. In this paper, we analyze different approaches to this problem both theoretically and in experiment. This leads to the proposal of a control methodology that uses switching between two different admittance control modes based on the magnitude of measured force to achieve disambiguation of the rotation/translation problem.
