Haptic broadcasting of grasping operation by multilateral control

Real-world haptics is the key technology for future haptic communication engineering. In this technical point of view, this paper proposes a novel haptic broadcasting of grasping operation by multilateral control. The experimental haptic broadcasting system has two master systems and one slave system. Since each system has two degrees of freedom, it is possible to control the center-of-gravity position and grasping force, respectively. Furthermore, the paper implements the identity ratio in each master to transmit the same environmental impedance to each master. The experimental results show the viability of the proposed method.
