hey, does anyone know if there are belts and pulleys for the vexbot or edu, and if there are, where can I find them
Not for VEX.
you can probably make your own
Pulleys can slip easily. It would be easy, but belt and pulleys are similar to chain and sprockets. So basically the kit is already there.
Having pulleys that slip may actually be a design requirement, as you may want a limited slip mechanism. I’ve used pulleys before with Vex, as I found some that use 1/8" diameter round shaft, and I just forced the square shaft through the round hole. They worked fine.
