LEGO Mindstorms NXT Coloured Ball Sorting Crane

LegoMindstormsNXTColouredBallSortingCrane

Good things do sometimes come from disasters. A couple of days ago I was attempting to lift down approximately 5Kg of assorted LEGO parts when the container took advantage of gravity, and headed straight to the floor. This ended in a completely empty storage container, and LEGO dispersed for metres about. Towards the end of the cleanup, I came across a pair of Green Mudgaurds from a LEGO Technics 8291 Green Dirt Bike.

UPDATE: LEGO Mindstorms NXT Tic-Tac-Toe Robot

LEGO Mindstorms NXT TicTacToe (Noughts & Crosses) Playing Robot was programmed with NXC, using Daniele Benedettelli’s ‘TicTacToe AI’ Code. It uses a Hitechnic Colour Sensor to detect the coloured balls placed on the playing board. The game has 3 difficulty levels starting with ‘Novice’ that places balls at random. Next is ‘Normal’, followed by the almost impossible ‘Expert’ level.
