Abstract
A twisted string transmission system comprises a twisted string actuator, a force sensor, and a controller. The twisted string actuator is for converting a rotational motion into a linear force. The force sensor is for sensing the linear force. The controller is for receiving sensor information regarding the linear force from the force sensor and for providing control information to control the rotational motion based at least in part on the sensor information.
