Abstract
In recent years, soft actuators having flexible movement attract attentions. There are some soft actuators such as McKibben actuator, shape-memory-alloy actuaor (SMA), functional fluid actuators, etc. But almost all of them are expansion and contraction type of actuators, so their application field is limited. If rotary type of soft actuator is realized, they will be easily applied to traditional robots, and also to soft robots. In this research, for the purpose of realizng a soft actuator which can output rotary motion, we developed an electrostatic motor made from flexible polyester films with electro conductive polymer electrodes fabricated by line patterning method.
