Hi -

I made this mostly wooden bot in 2006. I used a couple of small scrap motors. Maybe I had them from tape recorders. As I had no experience I started without gearing. That made some marks at the baseboards. I added some gears, but it was never very successful.

I used the L293 Quadruple Half-Drivers. I also use a voltage regulator. To save pins, the 3 bumpers are connected thru resistors and read by an analog pin.

The motors could just be turned on and off in forward or reverse direction. So the behavior was a very hectic. But I got a lot of experience and had some fun to.

I took some hard bumps into the wall. The wiring on the bottom of the board came loose and this little something was retired.

Follow light, bump into walls and beeps and blinks
