This is the arm that could supposedly break through concrete if needed. This is only the arm.... but what could the manipulator be? Wait... how fast will this arm move?

This arm was built to be virtually indestructable. We had fun making this arm and I am gonna have a lot of thing using this on the field, especially when you see the manipulator.
GO 1403!!!

Just as a side not, the quick grips are not really a part of the arm, just there to mock up the suspected attachment.

I have to say, that it is a very cool arm.
... Would be very nice to know how it works. how much does it weigh?

We have a big cylinder and plenty of speed, don't worry. The way the arm set up makes this thing very fast. No worries man...

If not use properly, yes, but our strategy is pretty much rock solid.

Your all thinking to off. It's got to be a sealed arm, air fils inside of it like a telescoping cylinder acutally two onve its extended it will do the standard rotate on a pivot to raise and lower. I'm right I know I'm right. Also think about it this way unless the cylinder was like microscopic bore it would never have toime to extend and retract for every tetra. Once filled topped off for leaks. I'm right I know I'm right.

You would be amazed how much you can do with not much air too. Last year we had a two stage arm, the first stage used two 1.5" x 2ft long rams, and the second stage used one fatty (2"?) ram that was two feet long. We could extend all three on a tank of air, and retract them (pulling the robot off the ground in the process) all within about 6 seconds. That compressor is fast and keep in mind that you can store the air at 120 psi. Additionally depending on how you plumb your pneumatics you can draw air from other rams essentially using them as tanks.

little bit of a change, its 20-25 pounds before we lighted it up. So it'll probably be around 15. The rest of the robot weighs like 80 pounds, so we should be under the limit.
oh and the time it takes for the arm to reach out and retract, you may find very suprising. Its a piece of art.
