Lab rats beware -- there's a new turbo-charged robotic cousin of yours on the block. This little autonomous fellow, Tetra, has just wowed micromouse hobbyists with a 4.766-second finish time in a maze (which had to be mapped by the micromouse first) in a recent demonstration, beating the previous All Japan Micromouse contest record by a big margin of 1.6 seconds. Sadly, Tetra wasn't the winner of this year's contest as it failed to complete the final Expert Class event -- probably something to do with the lighting conditions which affected its tracking. We can still admire Tetra's awesomeness in the video after the break though, followed by some thoughts from a few micromouse experts.
