Space is a real issue
Space is a real issue working with Wall-E. The next issue is taking it apart to get inside to add more. My original plan was to to the SD card and use WAV files for the sounds. The servos I already from a previous bot that I built so it was a easy solution and I actually prefer using the servos. I recently purchased a gyro and plan on using the ROLL to keep the angle down when wall-e goes up hill. I also plan on changing out the ultrasonic sensor for a Sharp IR sensor, this should provide better detection and navigation.
