This arm could reach to about 104" from the floor, though the height at which it would deliver a tetra -- that is, score it atop a goal by rotating down -- is a bit less. We haven't yet finalized a gripper design, though if you were to grab a tetra at its base, you gain some extra height for free as well.

It's weight is approximately 25 lbs., but the supporting structure was poorly thought out and quickly designed. I'm certain that there are better options in that regard that are as strong or stronger and considerably lighter.

The pivot point is a defining feature of this arm design as well as its latest iteration. It allows us better control of the arm position for obtaining tetras from the floor, the automatic loading station, and for scoring.
