I have posted this video to show how well the two drum winch works .
The lift we had previously prototype in alum. had to be replaced because
of its bending under attempting to lift 6 totes . The new lift painted red with new pneumatic arms should improve the overall performance of the robot. The winch shows no noticeable damage from about 4 hours of practice lifting .
