Tiny Light-seeking Robots

[Alex] continues to delight us with his projects. His third-generation tiny Braitenberg vehicle, a light seeking robot, is a big improvement over its predecessor, the mini Braitenberg vehicle. He’s moved from an Arduino based design to using the AVR ATtiny25v, replaced the breadboard with a PCB, and reduced the parts count. We think it was a great idea to use shrink tubing to shield the back of the photo-resistors from ambient light. Don’t miss the video of these little guys chasing a flashlight beam after the break.

    i want to see some really cheap, really energy efficient lightning bug robots out there. like, you’d pay $5 to make one or something, and on its own it would seek out light like these guys. but in groups they can communicate and figure out who is getting more light. be able to send out scouting robots. ie, robot #1-4 stays on the floor around your lamp collecting energy with solar panels while robot #5 is sent out to see how much light is coming from your monitor. make a hundred of them and let them loose in a state park, that’d be awesome.
    especially if they were shaped like crabs.
