Blue Bug

This is Blue Bug, not my first robot but the first one I am posting here... The body was made using a couple of old DVD's.

I used the herbie circuit from the book Junkbots, Bugbots and bots on wheels but made a PCB instead of free forming it. For motors I converted two servos that I already had to work as simple gear motors.

I mounted the phototransistors to make it look a bit more bug like, this has the added benefit of making them easy to adjust...

The tactile sensors in front are made from a guitar string.

Well done and clean build. I

Well done and clean build. I like the way he’s roaming around looking for light :slight_smile:

Thanks!

I appreciate the kind words…

nice job!

Looks like it works great! Love the guitar strings
