You guessed it, beat the HARD tournament and come in first in every race, and u should get the robot.
There is also a BONUS menu in the default menu, ie tournament, single race etc. It is at the bottom, i got it by beating the EASY but i didnt come in first, i think all u have to do is win the tournament.

To beat Beemer go beside a tree near the end and you will miss out on a hairpin.
