A PVC pipe with thermal insulator machined (sanded down) in the shape of a wheel. Very fluffy, so it adjusts well to the different tubes, but not very grippy - we still have to add something to deal with that.

We're using the RS 395 motors with a modified servo gearbox. Since our Banebots order hasn't arrived yet, one of the gearboxes is still using the original servo motor, which obviously will be replaced until competition time.

Re: Team 383 gripper prototype

Looks very nice! Does the arm telescope to reach the top pegs? It looks like it may from what I could see in the video.

Seems like it could have problems grabbing other shapes?

Re: Team 383 gripper prototype

how much pressure has to be in the tubes to pick them up? Can they be slightly deflated?

Re: Team 383 gripper prototype

This is just a prototype on top of last year's robot - we're testing the gripper here, not the arm, which is actually just a pole right now. The robot version will be a 4-stage telescoping arm.

We still have to fine tune the gripper, but yes, it can handle all three game pieces even if a bit deflated - we're considering adding a bit more pressure in the gripper to improve the "range" on flatter tubes.
