I figured I would just let it be known that I have some extra robot arms laying around taking up space in my work area here at home.
I have a pair of Omnibot 2000 arms, both in great shape, I have had them apart and cleaned them and well they don't have the Omnibot 2000 stickers on them and the grippers are missing the black rubber pieces that were originally on them. The motorized arm still works perfectly and the other arm that is adjustable is perfect also.
I also have a pair of Robie Sr arms, the arm that can carry a pop can or a drinking glass is complete, but the other arm that had the gripper hand is missing the gripper hand, but still a very good pair of arms.
I figured I would let it be known that I do have these extra arms :-}
I will be adding pictures in a few minutes from my tablet.
