Okay kids, this project is not for the novice. You need a basic knowledge of the arduino micro controllers and how to code for the arduino.

The sample code included with the kit is does plenty. The puppy plays, sits, shakes and follows.
The code is also open source! Which means I can hack or modify it anyway I like in the Arduino IDE.

The worst time I had with the project was troubleshooting. When I fired the puppy up, it just wiggled a bit then sat down, then nothing else.
After testing the servos, checking the batteries, and all the connections, it turned out I had two wires crossed.

I got the blue and the violet wires crossed on the IR Compound eye

The manual that came with the kit isn't great about how to wire the robot's eye to the controller so the puppy couldn't see anything, got bored then sat down.

Once I had that issue worked out, I didn't have further issues.
