Lego Mindstorms Tug Of War

In the LEGO Mindstorms Tug Of War Challenge, teams had to create vehicles that would be able to win a game of tug of war against other teams' vehicles. Most teams built wheeled vehicles, but I constructed a vehicle with treads. Initially I built a two-tread vehicle with two motors, and this succeeded against a number of teams.

After losing to a team, however, I resorted to adding a third motor and four more sets of treads to my design. I also utilized a gear mechanism in order to derive more power from the motors. This did not prove to be much of an aid, however, due to the lack of friction on the classroom floor.

In a final effort to derive more success from my robot, I strengthened the back bracket securing my rear drive block. This ensured connection between gears, and helped it do a bit better. I also competed with other robots outside on different terrain to much better results. Outside, I won one race and tied most others.
