Single-Motor-Based Bidirectional Twisted String Actuation With Variable Radius Pulleys
RA-L 2019
In this letter, we proposed a variable radius pulley (VRP) to linearize input-output behavior of twisted string actuators (TSAs). With the help of a VRP, it is possible to make the inherently nonlinear transmission ratio of twisted string constant. This enables design of bidirectional transmission s
