hi,
im a student and my dad picked up a kuka kr3 from the company in wich he works. managements say that is ok.
has been dismissed because of a broken encoder of the axis 1, as far as i know everything else is ok.
i can provide most (if not all) the documentation, the arm and the control unit (PC +Power Supply)
if anyone is intrested i can snap some photos.
about the price, i was thinking 1K€ (+ shipping)
