After many run ups and approaches, I've finally gone and built Robot Boy mk1. Starting with acorns etc. so it doesn't do much yet. Here's a video:
This is based on an Ardunio Uno, an Adafruit motor shield and the Maker 4WD chassis.
The shield arrives as a bag of components which gave me some much needed soldering practice. All done and I plugged in some power and a green light came on. Result!
A week later, I wired in the motors, knocked up a quick sketch for the Ardunio and crossed my fingers. Rather alarmingly, this time when I gave the shield power no green light. Somehow I had borked the shield in the intervening week - all it was doing was sitting on a shelf in that time!?!?! But no, it all worked first time, looks like just a dodgy green LED.
Anyway, this is it so far. It's supposed to turn a tight square but because some of the motor axles are bit off, it's a bit creative with it's angles. But I'm pleased with my first version, mainly because my soldering seems to have been OK first time round.
So, what's next? Some wireless I think. I'd like an RC mode from a browser.
