A haptic feedback system is required to assist telerehabilitation with ro-bot hand. The system should provide the reaction force measured in the robot hand to an operator. In this pa-per, we have developed a force feedback device that presents a reaction force to the distal segment of the operator’s thumb, middle finger, and basipodite of the middle finger when the robot hand grasps an object. The device uses a shape memory alloy as an actuator, which affords a very compact, lightweight, and accurate device.
