  • The twisted string actuation system is particularly suitable for very compact, low-cost and light-weight robotic devices, like artificial limbs and exoskeletons, since it allows the implementation of powerful tendon-based driving systems, based on small-size DC motors characterized by high speed, low torque and very limited inertia. The following activities has been done using the Twisted String Actuation System: - The basic properties of the twisted string actuation system. - An ongoing work for verifying the behavior of a twisted string actuator in contact with a sliding surface or guided through a sheath. - The implementation of a variable stiffness joint actuated by a couple of twisted string actuators in antagonistic configuration. - The design and the implementation of a force sensor based on a commercial optoelectronic component called light fork and characterized by the simple construction process. - A twisted string actuation module with an integrated force sensor based on optoelectronic components. - The preliminary experimental study toward the implementation of an arm rehabilitation device based on a twisted string actuation module. - A 6 DoF cable-driven haptic interface for applications in various robotic scenarios. - A wearable hand haptic interface driven by a couple of twisted string actuators.
