Atrx has posted

of his Lego Zil 43272T Trial Truck controlled by Bluetooth on his cell phone. The truck survives MULTIPLE rolls down a hill, so it is TOUGH. The video editing is excellent, and it shows how the various gears can shift. He wrote,

One of the advantages of using Bluetooth to control a Lego truck OUTSIDE is that it is not affected by infrared light coming from the sun. The Lego Power Functions controller only has a limited range of 10 meters (33 feet). The key piece to controlling NXT using Bluetooth is the Lego Bluetooth Dongle: http://shop.lego.com/Product/?p=9847 .

HiTechnic has some programs too.

Cool truck.

It did so many barrel rolls down the slope and it still worked. Impressive....
