2019 IEEE Robotics and Automation Letters  
In this letter, an angular trajectory tracking controller for a twisted polymeric fiber (TPF) actuator by the combination of a model-based feed-forward and estimated temperature feedback is proposed.  ...  TPF actuator is one of the soft actuators that can produce a rotational motion, which is made by twisting a nylon yarn and thermally treating it.  ...  ACKNOWLEDGMENT The authors would like to thank DENSO CORPORATION, Japan, for their kind and meaningful support.  ...
