Pneumosnake was developed as a cooperation between SINTEF and the Department of Engineering Cybernetics at NTNU. The robot was developed in order to investigate joint actuation based on pneumatic bellows. Three custom-made pneumatic bellows are mounted in each joint module. By regulating the pressure in each bellow, the motion along the two degrees of freedom in each joint may be controlled.
