Here, I've collected a bunch of commonly asked questions, and then answered them. If you can't find what your looking for, go to my robot links page. I have many other sites that also have FAQ's
Q: How do I attach a sprocket, pulley, etc, to a shaft?
A: Well, you could always use a setscrew, but these generally cannot withstand the forces involved to hold it on. A better way to go would be to drill a hole though the pulley (or sprocket) and the shaft, and pin it on. The best way would be to get a keyway cut into the shaft and the pulley or sprocket, and put a key inside. A keyway is basically a slot, and a key is like a bar of metal. See diagram below.
Q: How can a mount a drill motor inside my bot?
A: Drill motors are great to use! You get a (powerful) motor, battery, and charger all in one package, and for a decent price. But mounting them is a real pain. You could always just leave the motor inside the case, and stick a shaft in the chuck. Other people my machine custom mounts, or get a nearby machine shop to do it. Its all up to you, your abilities, and wallet.
