This is my first "from scratch" robotics project. It is currently incomplete.
The original idea for this robot was to create a "thomas the tank engine" sized robot that could pull my son's trains by following a hand drawn line.
I learned a lot from this project and intend to finish it.
- Run of the mill Infrared Emitter and Detector diodes from Austin Electonics (Local electronics store in Duluth, GA.)
- Microchip PIC 16F876A microcontroller (28 pin)
- ULN2801 Darlington Array
- tinybl serial bootloader
- Surplus Epson Unipolar stepper motors from All Electronics
As of September 2004, the circuitry is complete. The robot can detect a line and control its motors. To finish the project, all I need to do is make a little chassis, drive train, and attach the wheels.
The project is halted on several grounds.
- I got interested in hacking Billy Bass
- The motors are way Way WAY too weak. I built 2 experimental drivetrains to try to compensate for this. There is a quicktime movie on my website of it moving. Be sure to watch it, because whenever I try to demo it live, it rarely works.
