My first mobile robot and my first YouTube post!

Here I’ve taken an old tank RC toy, added some sensors (LDRs), some brains (a BasicX24 microcontroller), and some motor interface electronics (L293D dual H-bridge IC), written a little routine, and set things going!

It’s very basic at the moment but I’m quite proud that it was built nearly from scratch (except for the hacked toy).

It’s very messy and I’d like to tidy it up but I’m also eager to make some extra sensors and give it a bit more of an intelligence. The main thing to implement is bump or proximity sensors. Notice how the video ends as the robot hits an object it can’t detect!
