Abstract

This paper presents the 2-DOF haptic device in which DC motors and MR brakes are equipped. To apply MR brakes to the 2-DOF haptic device, its kinematic requirement is described by Jacobian analysis. Through the analysis, MR brakes can be used to display the damping force in a multi-DOF haptic device when it has the orthogonal Jacobian such as Cartesian manipulator. A five bar linkage type haptic device, which has the nonorthogonal Jacobian, is developed to verify the theoretical effort. Experimental results show that the five bar linkage type can't display the 2 DOF virtual environments due to its kinematic constraints, that is, nonorthogonal Jacobian.
