MR-2: fighter robot in LARC 2006, Cowbot category.

The robot was designed for competition Cowbot, in Latinoamerican Robotic Contest LARC 2006. Santiago, Chile.
Two robots face off in a duel, each with three ping-pong balls shooting (balabot) and use a ball last case added to the body (knife).
Have five minutes to complete the test, the first enemy fire and Match to win the match, or if he touches the ball first added to the body of the robot (stabbed). Be able to locate the robots via a beacon arranged in the top of the robot enemy, so detecting the sensor IR beacon could get the position of the robot opponent.

Got third Place in this competition, with my design.
