The mobile robotic platform is an experimental "built from scratch"
design with several unique features. It's behavior is very moth-like in
that it chases the brightest light that it can see. Obstacles are
detected and avoided with feeler wires on 3 sides. The "brains" of the Mobile Robotic Platform is a Basic Stamp I from Scott Edwards Electronics. The Stamp provides 8 I/O lines and programming in a dialect of Basic. I also added a Stamp Extender that provides an additional 16 I/O lines. The Stamp directly drives the motor and direction relays, LEDS and peizo buzzer. It also monitors the status of bumpers and polls light levels from its 3 photocell "eyes". The base is painted pine shelving material. Not only is this low cost, it does not require any specialized tools to work aside from a circular saw. It also exceptionally easy to mount, fasten and rearrange things. Future Directions - I would like to add several more Stamp controllers to make a distributed parallel architecture. This would allow more complex behavior responses and interactions with the environment.
