@GeeknRolla: Rummble founder reveals his start-up rules of engagement


With a webcam, digital signaling processing board, and some Lego Mindstorms pieces, creator Branislov Kisacanin put together what he calls the Tetris-Bot. The way it works is the Texas Instruments DSP board analyzes the screen and then communicates with the NXT robot through LED lights. The Tetris-Bot will then push the buttons on the number bad, which it can do at up to three strokes a second.

If you watch the video though, you might notice that the robot seems to be having some difficulty getting past level one. The robot certainly has a long way to go before it can catch up to the Rubik’s Cube and Sudoku solvers, but it’s a neat concept nonetheless.
