The dexterous hands are applied for tasks that are difficult for human to execute, such as dexterous micro operation and operation in extreme environments: space exploration, nuclear energy development and medical device. The dexterous hand master, as a haptic interface， can measure movement of the operator and display force feedback. From the idea of the computer mouse, we designed a simple compact master hand which is adapted to the human hand. It is manipulated on the desk. Each finger of this device has three DOF with feedback in three directions. The root joint of this device is designed in the use of leverage and its force feedback is transmitted from the DC motor through a rotation link. Front finger part of the device is designed based on the principle of ball mouse. We use a spherical ring wraps a ball. The rolling resistance, as the force feedback on the joints, increases with the contraction of the ring.Finally, we simulate the statics and dynamics of this device using ADAMS. The optimization of the design is based on the results of the simulation.Ke
