I decided to use a different base for the robot when I saw Walmart had cheap RC cars for about $10. I bought one of those, ripped the plastic top off of it, unhooked the motor wires, placed my Arduino and breadboard on top of it, and hooked the motor wires up to the H-bridge. This worked very well, all I had to do was change some code because now instead of using differential drive with 2 wheels, I was using rack and pinion steering with 4 wheels. This body is sturdier with better weight distribution, and with 4 wheels, it drives much better. A body, 4 wheels, and 2 motors for $10 bucks, not bad! Besides this reworking, I also fitted a servo motor with a wireless cam fastened on top. Using VLC, I am able to stream the live video feed from the camera onto my network. Using the VideoView control from the Android SDK, I am able to view this feed from my Droid while controlling the robot. Unfortunately, there's about a 5 second latency on the video stream on the Droid that I haven't been able to solve as of yet. I've been unable to find a solution to the problem, though others have experienced this grief as well. Anyhow, these major cosmetic changes to the robot warrant a new name for it. This new robot is named "Donuts", again thanks to Erin =)
**UPDATE** Since so many people have asked me for the code, I am sharing the Arduino and Android code here. The Arduino code is based on some older code that wasn't cleaned up so it's messy. Also, this was a good resource for me to learn how to get my Android app communicating with my Arduino via bluetooth. Thanks to all who have left comments, good luck on your projects!
