Oooo… Very cool.
Use of pneumatic bellows for joint actuation. Bellows are powerful, naturally compliant, and take up minimal space. Maximal coverage of all sides of all segments with extra wide moving tracks. Unique pneumatic control method allows simultaneous proportional control of stiffness and joint angles. The “drive shaft spine” is powered by a single electric motor in the center segment. The spine runs through the center of all segments and provides torque to the all tracks.
