Custom Board and Stamps
Actually, you can use the Basic Stamp II on a custom board to indirectly control parts of the robot by using the analog and digital inputs on the RC to signal the main program as to what action to take. You can have much more complicated program on the custom board the would be free of the delta_t timeout and it's all legal under the rules.
We are planning to also use hall effect transistors and I also want to include some photo interrupters for speed sensing.
By the way dkeith once the stamp is programmed, you don't need the carrier board. The "button" command can debounce your inputs or you can use a quad CD4044 S/R flipflop (99 cents) with 1K pull up resistors and avoid programmed debouncing ... so socket the custom board for the Stamp, program it with the serial board off robot and plug it in when you're done... gives you an additional $20 or so for additional parts on board the robot. As for serin serout ...there is an example in the Stamp manual that works really well. I've coupled two stamps together using the method they described and it works great!
