At first, nothing happens. Then, at about 5-10 PSI, the flat strip of silicone will suddenly curl into a "C" shape. Release the pressure, and it springs back to straight.
This isn't science fiction. It’s a growing field where engineers swap servo motors for air pumps and replace steel joints with silicone rubber. The result? Machines that bend, twist, and grip with the gentle grace of an octopus arm. Soft Robotics- A DIY Introduction To Squishy- Stretchy- And
That’s the fun of it. Soft robotics is still a wild west of design. There is no "standard servo." Every squish is an experiment. At first, nothing happens
