Re: 296 prototyping
Well the vacuum arm is a retrofitted version of one of our older bots - the claw which was on that arm originally is what you see on the forklift. For the rotation of the tube, we used a 1/4 inch bore pneumatic piston to rotate one of the two clamp pads on the grabber, the other one is free-rotating.
We think the forklift idea is really cool - there`s a way to actuate the entire lift motion with only one motor (if anyone wants the details I`ll post them). the problem is that our claw right now is sticking out almost 30 inches - we need to figure a way to fit inside the box.
