Re: Caster Mechanism
Yup, one team that used this type of caster mechanism was the Cheesy Poofs, team 254. I have a feeling that they used pneumatics though, not a window motor. They used the caster to alternate from 4 wheel tank drive and 2 wheel car drive. Why do you want to do it with just one window motor? Do you want this mechanism to use 2 casters to lift up the end of the robot? The Cheesy Poofs only used 1 caster. What I am going to assume is that you want to lift 2 wheels off the ground so you can steer differently. In this case, you only need to lift those wheels off the ground by like, a centimeter, so I think pneumatics is the best solution for this problem. To turn a lever with that much force will demand for some pretty thick shafts. You'll probably have to attach a sprocket to the window motor and gear it down a bit, and all this adds up to a lot of useless weight. You could do it with a window motor, but I strongly suggest doing it with pneumatics. All you need is a small cylinder with a thick bore, so it can give the 65 pounds of force. Stick a caster on the end of that, and you're done.
