Autonomous robotic bulldozer

Tuesday, September 25th, 2007

Here’s a YouTube of a totally autonomous robotic bulldozer. It uses the new Power Function (PF) motors, which are totally controlled by the NXT via infrared signals through the new HiTechnic ‘Infrared Link’ (or IR-Link) sensor about to hit the markets. This “sensor” would allow you to control up to 4 IR recievers (so up to 8 motors!) without any output port of the NXT. You can see the bulldozer scanning the environment with the Ultrasonic sensors and then flattening anything in its path using the Ripper and the blade. Thanks Tim for sharing this with us!
