More about the Spine Robot here
Mark Pauline finally got the spine robot assembled. Works good! Even with hand power using lever arms, it can be moved around very smoothly and does not wind up like before. The drum winches are cool! Next is to put the high torque hydro motors on it. 800 ft lbs each with no drive ratio reduction.
