Would have to be this year's robot. Only our second year, we seeded well enough to be the 7th ranked alliance at the Las Vegas regional. Our robot was liked enough to be chosen to an alliance by both 116 and 233 at regional competitions. Then we played great at the World Championships, was quite happy with our improvements over last year (though last year our robot took us to the World Rookie All-Star award, so it wasn't too bad either
).
