Just read every technical thread here on CD...you'll learn all you need to know, but it might take you a while!

Seriously, you kind of need to learn one thing at a time. Like in school, you have detailed lessons about different things every day or every few days.

I'll start with motors. The CIM, like all the motors we use on FRC robots, is a permanent magnet, brushed motor. The CIM is the biggest, heaviest, most powerful one we've had for the past few years. Other motors include Fisher Price, BaneBots, AndyMark, and Mabushi, and various automotive power window motors. They're all PM brush motors, but some are designed for higher torque, some for higher speed, some are lighter, some have gearboxes included, etc.

To figure out what motor to use for a certain part of the robot, you have to figure out what is required. The main things are speed and torque. You can also look at speed and torque as how much electrical power the motor can turn into mechanical power. You'll find a Watt rating on the data sheet that lists the technical specifications for the motors
