Battle Bots

My Battle Robot

I am taking a robotics class. Our last assignment of the semester was to build and program battle bots to compete in class. Two robots at time compete on a 1 by 5 foot board. Last robot on the board wins.

My strategy was to make my robot as heavy as possible. I put as many Lego pieces as possible on my robot. My robot weighed about 2 pounds. I programmed my robot to drive at full power infinitely until the touch sensor gets pushed.

My classmates had a lot of different robot designs. One robot had a arm that would come around and whack the other robot off the board. Another robot spun in circles to knock the other robot off the board. 

The robot that nearly beat me had a 4 wheel drive system with a worm gear.  the worm gear locks the wheels when the motor is stopped.  My opponent reprogrammed his robot to take advantage of my robot's weakness.  My opponent's plan was for his robot to stop when it hit my robot, waiting for my robot's wheels to fall off, and then his robot would push mine off the board.  In the battle, the worm gear of my opponent's robot popped off and fell into the steering transfer case.  This allowed my robot to push his robot off the board. 

I won the competition! The prize was a 140 piece Lego Technic motorcycle and 100% on the next paper.
