Robot ants: mini-machines mimic insect colony
http://www.bbc.co.uk/news/21956795Scientists in the US have built and tested robotic ants that they say behave just like a real ant colony.
The robots do not resemble their insect counterparts; they are tiny cubes equipped with two watch motors to power the wheels that enable them to move.
But their collective behaviour is remarkably ant-like.
By being programmed simply to move forward toward a target and avoid obstacles, the robot colony finds the fastest way through a network or maze.
