The controllable soft actuators with inflatable structures have been extensively explored recently. However, the previous approaches may require specialized materials or equipment in actuator fabrication. This work aims to create a pneumatic actuator with low cost and easy fabrication procedure. The proposed actuator adopts twisted balloons and polyethylene film with common sewing machine. The proposed device is easy to build for common user, so we believe that the proposed pneumatic balloon actuator can be easily applied to the applications for education and entertainment purposes.
