The playground is 170cm X 130cm, including the goal post. The CCD camera is placed at a height of 2m above the playground. Each team will have its own host computer. The duration of a game shall be two equal periods of 5 min each, with a half time interval of 10 minutes during which the participants can change batteries and modify the strategy. The robot system is composed of the battery, the motor driving parts, the micro-controller and the communication part. Communication between the host computer and the robots is wireless using infrared transmission technology. The host computer of each team sends data to the robots to control them. The information sent is the velocity of the left and the right wheel of each robot. The human operator should not directly control the motion of their robots either with a joystick or by keyboard commands under any circumstances, except start, stop and restart commands. Other information, such as game strategy, can be communicated to robots only when a game is not in progress. The rules of the robot soccer, which are defined by FIRA (please refer to the rules in the FIRA homepage, (http://www.fira.net), are similar to a real soccer game including fouls, free kicks, penalty kicks. etc. For each team, the robot soccer system is mainly composed of three robots, the vision system and the host computer. The vision system contains of a color CCD camera and an image grabber board for processing the image information. The camera is the external image sensor. The cooperation and control of mobile robots and the game strategies have to be implemented. The host computer transmits commands about the strategy after processing the vision data, which contains information about the position of the ball and the robots. The objective of the Internet education program is to understand the functioning of the micro-robots, the robot soccer system in general and how to design of the application software. GAME RULES http://www.fira.net/soccer/mirosot/rules_slm.html MICRO ROBOT MAZE   IIn this category you will build a micro robot that is sized less than 5cm cubic and program the robot for running through the maze. The robot must pass the 2 checkpoints - Point 1 and Point 2 and arrive at the end point. The robot, which passes all the checkpoints and finishes in the shortest time, will win the contest. The micro -robot runs through the paths between the squares with 2 tactile sensors placed in front.   The sensors make it possible for the robot to find out whether there is a wall in front. If the micro-robot approaches the wall, the tactile sensor turns on, and when the micro-robot moves away from the wall, the tactile sensor turns off. By using this mechanism the program for running through the maze must be written. The robot uses the 89C2051 micro-controller, which is the brain of the micro-robot. It also contains memory for storing programs. It receives the data from the tactile sensors, judges the environment and controls two motors. ROBOT TAEKWONO   Robot Taekwondo is an martial art on a square playing field sized 1m x 1m done by micro-robots, which follows a simplified version of Taekwondo rules. The overall Taekwondo robot system is the same a robot soccer system adopted by FIRA. It uses an overhead CCD camera over the playing field as a vision system for locating home robot and opponent robot by detecting color patches. As team colors, blue and yellow are used as in MiroSot.   It is one-on-one game between two MiroSot robots with an attachment of color target patch. Goal is to attack the target patch attached to the rear side of the opponent robot. The game has a score defined below and consists of two rounds. The winner is decided by score. As the game is a kind of fighting, it is allowed to push the opponent robot outside of the playing field. Thus it is scored if the opponent robot is pushed to outside of the playing field. Figure show initial positions of the robots.
