Over 140,000 children are participating in this year’s FIRST Lego League (FLL) tournament, comprising 14,725 teams from 56 countries. That’s almost a 14% growth over last year’s participation, as the chart on the FLL site shows.
Starting from the pilot tournament in 1998 in which 210 teams from 2 countries participated, FLL has grown steadily across [...]

Here is an interesting creation using Mindstorms NXT, a Rolling-Orbital-Bluetooth-Operating-Thing (ROBOT) as its creator calls it.

Spherical Robot 02 (YouTube)
This project uses two NXT controllers: one inside the “thing” and an external one that acts as the remote control. The two controllers communicate via Bluetooth. The external controller is also uses NXT motors that are very [...]

I found this cool video demonstrating how to build a Wii-like remote control using Mindstorms NXT sensors. This project uses the compass and acceleration sensors that are not part of the standard NXT kit, but can be purchased separately. RobotC is the language used for programming.
