Experimenting with soft robots doesn’t have to cost a fortune. Programmable-Air is a hardware kit with everything you need to play around with inflatables. It comes with compressor/vacuum pumps, 3 pneumatic valves, and pressure sensor, with everything controllable via Arduino Nano.
Programmable-Air has a single tube that goes into your soft robot. By controlling the valves and motors, you can push air in and out of the actuator. This kit is based on Arduino Nano. The above video gives you a better idea what you can do with it.
