ROBI was primarilly created for the purpose of testing out different types of available microcontrollers. I ended up going for the OOPic Microcontroller produced by Savage Innovations, because of the ease of use and programming. Robi consists of 2 Modified FUTUBA servos (I traded a guy at a hobby shop for a used video card I had laying around. And modified them myself.)A swivel caster for guidance. 2 Front wheels of off my RC car. Two microphones used as "ears" one on each side, (I amplified the output of the condenser mic's through two 741 audio amps, before feeding them into the OOPic's analog input's.) 4 Bumper switches, 2 in front, 2 in back, for navigating around obstacles, etc. Other misc. parts : A piezo buzzer for sound effects, Some indicator LED's, a 4 X 4 Matrix keypad, for programming movements, or running other pre programmed movements, i.e. Dance to music, find source of sound while navigating through its environment, run from sound, and other cool and funny things. Soon to be added to its array of instruments: Davantech Sonar Ranger, a Serial LCD to display messages, and as soon as I hack into a Texas Instruments Voice synthesizer module, it will also speak! (All this is driven by the amazing OOPic!) So far the cost is around $86.00 (USD), that's only because I had to bid on the TI Voice Synth. on Ebay, and I also spent $35.00 on the sonar ranger, and $35.00 for the OOPic. The rest of the parts were salvaged from electronic equipment I have acquired from repairing them, or just simply tear other things apart to get parts!

I'm also working on another OOPic based all terrain autonamous vehicle, and maybe even modify my riding mower, so I won't have to drive it in the hot summer sun, instead, I can be in the shade relaxing!

If you have any questions or comments about any of this just email me and I will get back to you.
