 +We started with the pneumatic wrist brace, after getting all the materials
  
 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 .

 +To avoid the air goes outI 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 ​ }}
