Meet Tetra, officially the fastest mouse on four wheels. Stuart Little's got nothing on this guy.
Tetra's completion of an "expert class" maze in 4.7 seconds shatters last year's best by more than a second in a half, which in micromouse terms basically makes it the love child of Carl Lewis and Michael Phelps. But what makes him so good? For that we'll have to turn to this jauntily scored interview with David Otten, a 22-year veteran of micromouse competitions. Because apparently people have been racing robotic mice around mazes since at least 1987 and NO ONE EVER TOLD ME ABOUT IT.
