Then in order to stay perpendicular to the wall we are going to mount the cable to the back of the frame as well as the motor.
We haven't been able to test this yet as it is the last thing we would put on our robot given the time. I would recommend that you don't focus on the lifting until you have everything else perfect. The lifting is one of the most difficult challenges and has a very small benefit. I mean you get 10 extra points for adding an entire new subsystem.
Either way good luck with this, it will be challenging.

That is basically what we have. We have a solid working shooter right now so we developed a climber. Should be done tomorrow. We have 3 telescoping PVC pipes connected with surgical tubing and para cord that get winched up extended the hooks to the bar. The hooks are then attached to a separate winch with some pulleys to balance the weight. I do not know how well or even if its going to work but I should be able to tell you tomorrow.
