A new pneumatic linear actuator made of a thin flexible rubber is developed for locomotion in narrow paces. The actuator is named "tetra chamber actuator". This new actuator has an ability of object transportation and locomotion. The actuator was designed based on non-linear FEM analysis considering geometrical and material nonlinearity, fabricated and(More)
A pneumatic multi-chamber rubber tube actuator was designed, fabricated, and tested. Applying pneumatic pressure to each chamber sequentially causes periodical motions of the rubber tube surface tracing a polygon shape. By winding a pair of the tube actuators in parallel spirally around a colonoscope, they generate deformation waves around the colonoscope(More)
