Collision Avoidance Control for a Multi-fingered Bimanual Haptic Interface

To present three-directional force at ten fingertips of both human hands, we previously developed a multi-fingered bimanual haptic interface consisting of two five-fingered haptic hands and two interface arms. However, there is a risk that haptic hands and interface arms will collide while a user is manipulating the haptic interface. To alleviate this risk, we propose a collision avoidance control for the multi-fingered bimanual haptic interface. In particular, by constructing the collision avoidance using a penalty method, we hope to reduce the user's feeling of collision insecurity. Through an experiment, we investigated the validity of the proposed control law.
