Re: Interesting belt problem

I'm not sure exactly how your shifting takes place. Are you actually moving the belt to shift.? Anyhow, I have had only one experience with belts on a FIRST robot and based on that experience I would never use them again. I don't belive there is any mechanical job to do on any (robust) FIRST robot that is best done by belts. I wish someone could prove me wrong but I just do not have good feelings toward belts. They are a nice lightweight solution but as you have pointed out, durability and reliability can be a major problem. Especially over such a small distance, it won't cost you much weight to go with sprockets and chain or gears instead.

In your shifter-box, is it possible to replace the pulleys with gears? Or with (small) sprockets and chain?
