 I have some problems, that were:
-. The silicone I've found here in Brazil is not very elastic, so when I inflate the gripper to test and after I should still wrap each leg with the ribbon to more resistance and control of the movement, but as I said the silicone rubber produced, was too hard. Also I think I've made a layer too thick above the air chamber, so it almost doesn't move with the air pressure.

 Pressing the air inside the botlle I can see some movement but not enough to move the gripper's legs.
-Than I've tried making another piece with less thickness above the air chamber and with less catalyzer to see if the silicone rubber would be more flexible, but at the end it doesn't polymerize very well and I couldn`t unmold perfectly the basis.

 So I'm trying to obtain another kind of silicone to make everything again.
