Thanks for the feedback.

There are definitely tradeoffs between a chain-lift and cable-lift. Let me see if we can summarize the differences.

Chain-lift:
handles more torque but heavier
needs more structure and pieces to implement

Cable-lift:
lighter but has the potential to slip or snap the cable with too much torque
easy to implement but more prone to failures


Teams can see some of the differences between the robots in Ri3D.
Team Indiana is a Chain Lift
Most of the other Ri3D teams are cord-lift
