Finally finished my scratch-built/junk bot(After 4 years!), only due to having to find the motors and parts. It's your usual line-following robot, partially designed by me, partially designed off of Sandwich from "Robot Building for Beginners". With a slelack finish!
I've made several improvements to it:
- Auto Adjusting Headlights via a PNP Transistor and CdS Photocell
- Lighter, yet still capable Motors - 2x Maxon RE Max
- High Amp Drive Transistors(8A) - Guess their overkill for two 400mA Motors, but had them lying around.
- Noise Reduction Caps
