perhaps some sort of locking device for your arm. something with one or two of these that locks the arm in place when it isn't being driven, it could reduce the amount of bounce and slop in the arm and make it smoother, and thus easier to place tubes.

It could be used in a similar way of 254's to let go of the tubes without the use of a roller claw.

Whatever it is, I can't wait to see it at CALgames!

The guesses about drive shifter are correct. However, there is something odd going on, as this is not strong enough to shift our usual gearboxes (9/16" doesn't sound much bigger, but it has a lot more force).

We've already got a clamping grabber ;)

We likely won't be there, the cost is much higher than other CA events, and they won't allow us to enter multiple robots.

Ball Lock would require a tad bit more force than what that guy can provide.

Shifting sprockets? like on a bike.

Go go gadget power take-off device.

4.5 pounds of force should be plenty to shift a ball lock shifter

We are in the middle of our ball shifter transmission design so that's what I was thinking they may be doing as well. I'm really curious how folks are reducing friction within the ball shifters - Ooopps, off topic.... (off to contact 987..)

Thanks for all the cool replies guys, we'll try to post another teaser tomorrow, and one more each week until we finish.

Already said it was for shifting ;) A plain 'ol dog shifter at that as well.

Let's do a little exercise in rule reading. Name all the rules this would violate.

Dog shifters and PTO aren't mutually exclusive. ;)
