Ive always been interested in flocking behaviour and they way nature moves about. But most experiments are done simulated. Valentino Braitenberg has written a great paper on how you can create behaviour with a few simple rules.
Every robot has a sensor, and if that sensor sees light it will move faster. This will create a "love reaction" because as soon as the robot sees something it get active and wants to get too it.
But this time the source of light is on the robot itself. This means that every robot is reacting on eachother. which ofcourse creates flocking! The whole installation had around 50 tiny robots all doing theyre own thing. they make an amazing amplified sound together.
Ive written a simple research paper on this project which you can download HERE!
