Library's collection Library's IT development CancelFootball has it's own fans. A goalkeeper, although not important, gives a
good advantage of defense. This condition gives an idea to make a goalkeeper
robot.
The robot system planning refer to the goal keeper movement. The
construction using AT89C2051 microcontroller as a robot's brain, InfraRed
sensor detector, and CANON DC motor.
Infra Red sensor transmit a signal simultaneously from the right and left side
of the robot. There are four conditions of the robot's movement, based on the
signal reflection. If signal reflection comes from left side, robot move to the left.
If signal reflection comes from right side, robot move to the right. If none or both
signal reflections receive, robot is in steady condition. Experiment show that
maximum speed for better achievement is 2 m/s.
