Printable Actuators with Computer Aided Design Preparing for International Journal of Robotics Research: Ryuma Niiyama, Xu Sun, Cynthia Sung, Byoungkwon An, Daniela Rus, and Sangbae Kim
Fabrication Process Heat Drawing Heat Stamping
Integrating PPR Fabrication Processes Pouch motor with self-folding structure, and computer aided design? Pneumatic structures that can move with no electronics at all … Pouch motor with Penn’s pick and place 3D printer? Pouch motors are made with thermoplastic materials. They should be able to thermally bind to 3D printed structures.

Performance: Linear Tension Test Force (N) Position (m) Test set up
Performance: Angular Torsion Test Test set up Ryuma Niiayama, Daniela Rus, Sangbae Kim, Pouch Motors: Printable/ Inflatable Soft Actuators for Robotics, ICRA 2014,
Control: the idea Tension - Knowing the relationship between tension force and pressure at a given position (distance between the two joints), by controlling pressure, we can control tension force. Torque – Similarly, knowing the relationship between torque and pressure at a given angular position (starting angle of the two joints), by controlling pressure, we can control torque.
Control: the method Velostat and strain gauge for pressure sensing Velostat is a back, opaque, volume-conductive, carbon-impregnated polyolefin
