Out of curiousity, what motors are you using to control the arm joint angles?
And I am also wondering... what is your drive train setup? I see that it is 4wd, but not much else.
And the telescoping... how is that done? (I think I am seeing telescoping sections on the secondary arm)

Hopefully I will be able to see this in action.
Great job!!

We did have issues with the tetras sliding down but if you notice there's a cross piece on the end of the arm which holds the tetras out at the end of the arm. The arm is being controller by the CIM motor for the lower arm and the van door motor for the upper arm. There's a variety of gearing in there that you really can't see in the picture.

The drive is three-speed four wheel drive. The front wheels are modified wheel chair wheels and the rear are custom wheels.

The telescoping only happens once at a beginning of a match and then locks in place.
