Can I take all the parts from it and install them on the Shadow? Going to be teaching a class in the spring and want to use the Redbot Shadow chassis but want to see if first. Would rather move me existing parts than buy a new Redbot.</p>

This now turns much smoother and without a cringing noise!</p>

I bought just the chassis because I bought the Make:It Robotics Greer motors form a Radio Shack that closed. I found out upon receiving my chassis that they aren't 100% compatible. The Radio Shack motors do not have the extended shaft for the encoders. The front motor mount would have to be be modified to fit the Radio Shack motor. I thought I would put this is information out there for other people who might have this same idea.</p>

I also just discovered that the Redbot is available as a complete kit. Is it possible to put the rest of the components for a complete Shadow in a separate kit? (For student-friendly orders, out of stock components can make ordering complete sets of "works" a challenge.)</p>

Links to an encoder an line sensor won't make it move. It also looks like everything uses 3 wire jumpers - where are these? Thanks.</p>

https://www.pololu.com/product/2598
You need to drill the center out to 3/32 on the PCB and 5/64 on the magnet to fit the magician motors.
The magnet is three pole so you get 12 QEP per rev.
The motor is 48/1 so you end up with 576 pulses per rotation of the wheel.
The wheel is ~2.56 inches in diameter or roughly 8 inches in circumference aka ~72 QEP per inch of travel.
Cheers!</p>
