First, there was Mickey Mouse. Then came Mighty Mouse. Now, at the dawn of the 21st century, comes micromouse, the little robot that could. Actually, a total of 13 micromice visited the UC San Diego campus last month, for a competition pitting teams from eight universities. It was the first Southern California competition hosted by UCSD IEEE at the Jacobs School of Engineering, but Kansas State University joined in the fun too. Fittingly, UCSD teams took first and second place in the competition. UCLA came in third.
