So I recieved my EvalBot last night and I thought I'd give a quick pictoral on the assembly. Here's the box as I received it: There were 2 boxes in the set: One box had the misc hardware and destruction manual while the other held the main populated circuit board: Pictures of front and back of populated circuit board: After all of the parts were removed from the circuit board: Assembling the drive motors: It's important to note here that the wheels are 3 circuit board layers thick and the holes must line up so that the optical sensors on the main board can pass light through them to keep count of rotations. Also, there are 2 set screws that are holding the 3 boards together. I recommend getting some channel locks or vise grips and holding the alignment of the wheels together so that when you insert the set screw the boards do not separate. Sorry I didn't get any better pictures of that. As it sits completed: And powered up:

It's a KM-12FN20.
But looking at my bot and that pic it appears the gears are in the exact same place.

Word to the wise:
If you have pets, don't let your EvalBot run over a fur ball.
Fur+tiny gears=very frustrated bot owner.

The 3 ratios mentioned are the 3 stages of rpm reduction for the gear set. There is no way to actually change ratios.

Word to the wise: If you have pets, don't let your EvalBot run over a fur ball. Also, don't let your furball run over your Evalbot. ;D

My dogs and cats have no interest in it. I guess because it moves too slow.
