+ | |||
+ | 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. | ||
+ | |||
+ | Then I did iron the 2 pieces with a protection sheet to avoid the urethane sticks to the iron. | ||

+ | |||
+ | The second step consists on putting air into the 2 sealed sheets: | ||

+ | |||
+ | 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 }} | ||

+ | And finally did put air inside | ||
