Older robot with swept object-avoidance sonar -- need software/code
I have an early Prop-1 "Activity" bot that has a third servo that sweeps an ultrasonic measurement unit back and forth. If the robot encounters an object, it backs up, positions itself to avoid the object and moves forward. I need the original demonstration software (SPIN) and documentation for this robot so I can demonstrate it to a class.
The board is labeled, "Propeller Activity Board" with the number 32910 and "Rev A". The continuous-rotation servos have add-on rotation sensors and attach to the board with three wires, red, black, and white. I think this arrangement is obsolete.!!
I would greatly appreciate any help, having spent several hours searching without results.
Many thanks. --Jon
