I haven't actually tried this, but I can hardly imagine that the
pressure generated from just squeezing one small part of the tube is
sufficient to extend a cylinder and press a touch sensor. The pressure
generated will probably just "vanish" in the rest of the tube.
In normal pneumatic operation, several pushes on a pump is normally
needed to extend a large pneumatic sylinder.

| How 'bout this as an alternative. A flexable containment, possibly the moderate diameter rubber tube, inside which are two circuits. One is a continuous metal strip which runs along the inside edge of the outside wall of the tube. The second is a (...) (26 years ago, 18-Dec-98, to lugnet.robotics)

| For those of you with LEGO pneumatics, I've got a question. There seems to be a need for an all-around-the-robot bump detector. Would this work? Wrap soft rubber tubing around the robot, seal one end of the tube, and connect the other to a pneumatic (...) (26 years ago, 18-Dec-98, to lugnet.robotics)
