Some people set the bar high when they're playing with LEGO®, taking on ambitious projects that push our understanding of what the little bricks can do.
The Electrical Engineering department at Oslo and Akershus University College of Applied Science have created a bridge laying robot using two LEGO® Mindstorm NXT microcomputers that communicate with Bluetooth.
Using servo motors, linear actuators, colour sensors, touch sensors and ultrasonic sensors, the robot can unload a bridge across a ravine, drive over it and then reload the bridge without any assistance from the creator.
