The present invention relates to a soft actuator moving linearly against external stimuli whose expansion and contraction can be actively controlled, suggesting that the actuator of the invention overcomes the problems of the conventional soft actuators, The soft actuator of the present invention can be repetitively driven quickly and accurately by controlling heating and cooling by using thermoelectric effect and, the soft actuator of the present invention can realize bending, tensioning, compression, and rotational driving of a tubular device containing a driver.

Soft actuator using thermoelectric effect

Provided is a leg type traveling apparatus including a bicycle frame, a travel module including a leg type front traveling unit rotatably mounted to a front of the bicycle frame and a leg type rear traveling unit rotatably mounted to a rear of the bicycle frame, a drive unit to drive the travel module, and a control unit to control the drive unit, in which the control unit includes a pedal detector to detect a rotating speed of a pedal rotatably mounted to the bicycle frame and a controller to control a driving speed of the drive unit based on detection information provided by the pedal detector.
