Twisted string actuator

WebAs an emerging compliant actuation mechanism, twisted string actuators (TSAs) efficiently generate linear contraction by twisting strings with a motor to shorten the strings’ length. Compared to other actuators, TSAs possess unique advantages, such as simplicity of construction, large force outputs, and high energy efficiency. WebWe present a novel design based on the under-actuated da Vinci’s mechanism driven by a flexible twisted string actuator (TSA). The distributed drive scheme allows structural optimization using a motion capture database to reproduce the natural movement of human hands while keeping adaptability to free-form objects.
