Climbing soft robotics

The present invention relates to a new pneumatic-actuated multifunctional doming actuator. The doming actuator can be used as a doming actuator, which can maintain machine/robotic operation on vertical surfaces without falling. The doming actuators exhibit rapid switchable adhesion/deadhesion on target surfaces upon pressurizing/depressurizing the embedded spiral pneumatic channels. The present invention also relates to novel load-carrying and climbing soft robots using the doming actuators. The soft robots are operable on a wide range of horizontal and vertical surfaces including dry, wet, slippery, smooth, and semi-smooth surfaces. In addition, the doming actuators can be used as a driving actuator for swimming soft robotics and as an actuator for soft grippers.
