Webproperties significantly. Given that TCP muscles are mainly made of polymers, it is necessary to investigate the change in characteristics, during the actuation process, to make any modeling more reliable. There is much research for every type of polymers and their characteristics in different temperature levels. WebIn this paper, a multi-functional soft robot module that can be used to constitute a variety of soft robots is proposed. The body of the soft robot module made of rubber is in the shape of a long strip, with cylindrical chambers at both the top end and bottom end of the module for the function of actuators and sensors. The soft robot module is driven by supercoiled …
