First of all I downloaded the design to cut on the vynil cutter, the material I used was an urethane. | First of all I downloaded the design to cut on the vynil cutter, the material I used was an urethane. | ||

I cut the 2 mirrored pieces . Then I cut a piece of baking paper a little bit smaller than the urethane one. This will avoid the 2 urethane pieces stick to each others. | I cut the 2 mirrored pieces . Then I cut a piece of baking paper a little bit smaller than the urethane one.

+ | To avoid the air goes out, I made a backflow valve (steps 3,4,5) and works nicely. | ||

+ | As we couldn’t get the silicon at time to make the soft gripper, I did experiment a bit more with the vinyl-inflatable. I decided to design a new form, like a worm and see how it moves as it swells.{{ :fabricademy2017:students:nuria.robles:soft_robotics:gusano1_sm.png?nolink&600x650 }} | ||
