In chapter 2 it talks about gears. It talks about how to county teeth to get a gear ratio that you can use to convert speed to power (toque). The teeth in a gear is used to mesh with the other gear pushing making it spin. The tuque and velocity are different things one is the power the other is the velocity of the robot. to get speed you need a gear with many teeth that drives a gear with less teeth to get tuque you need the opposite with one gear with less teeth and the other gear with many teeth.
A gear that is useful is the worm gear because it can only move in one direction so if you are trying to lift a arm then the arm wont fall down.
Another wheel is the bevel gear that is used to change direction with between perpendicular axis.
The last wheel is the know wheel. That wheel is actually not a wheel it is a four pieces gear that one part that pushes the other parts

Alright, I can see that you have clearly answered my questions. Just note that it is "torque" not "tuque" (yeah, it is very minor). I like the fact that you also mentioned the know wheel, since we used it in our robot's obstacle race course.
Nice and short summery Chris. But I was a little confused with different kind of gears; are they gears or wheels? because you say "another wheel is ... gear"? and also I think the right term is "Torque" and not toque... A little typo there =D
I was amazed by your absolutely wonderful job, especially your quick application of what you learnt in this chapter(Knob wheel)XD
