Re: Articulating tubes on roller claws

Put a backstop so the tube can only rotate so far, and all you have to do is suck in till the tube hits the stop.

11's roller claw worked this way. Big wheels on top slightly tilted the tubes upward.
You're probably definitely going to need 2 motors to articulate a tube.

More to the point, stop worrying about whether your "Atlanta bot" got screwed over or whatever. Worry about whether you've got an "Atlanta team."
