1) Objectives
Legged Robot is a kind of good education robot for the youngsters to understand the human walking patterns. Students can learn how human walks through applying for the system to the robot instead of using wheels; CPU processes the signal from sensors and instructs the robot to avoid obstacles. This may give students the basic idea of how the human brain works.

2) Participants
Challenge League

3) Team Formation
2~3 persons and 1 robot per team

4) Game Method
A playground assigned by the committee will be used for Legged Robot Obstacle Race. All robots start from a starting point and the robot that successfully passes by all obstacles and reaches the final point fastest will be the winner.

5) Game Rules
* Robot should be constructed in 3 hours.
* Robot should have at least 2 legs during movement any other driving pattern is not allowed except legs. (Leg number has no limitation.)
* Electric power resource should be less than 11V. (1.5VX 6 standard)
*Robots could be reconstructed and modified automatically or by the participants; a combustible device is not allowed. Direct control by the participants is not allowed as well; participants could only contact the robot when it is starts the game.
* The participants should use a controlling part of robot after setting up in advance; on the contrary, other parts except the controlling part should be constructed on a field spot.
*The IR/RF remote controller is not allowed.
*Robots must stop more than 5 seconds on the finish line.
*The playground would be announced on the game day.
*A computer is allowed for programming; participants should prepare for the computer.
* Robot should work with an independent electric power supply. Burning power (e.g. engine) is not allowed.

6) Playground
* Playground size is 50cm x 240 cm (width length)
* Obstacle (October. 6, 2003)
  -round abstacle diameter is 15cm and over, height is 15cm and over
  -square abstacle size is 25cm × 3cm × 15cm (width × length × height)
  -triangle abstacle size is 20cm × 20cm (base × height)
* Only the obstacles assigned by the committee could be used

7) Method of Scoring
* Race records decide ranking. Ranking is decided by the average of two recorded tracking time
*Sensors record tracking time. In case of unexpected situation (out of power, sensor breakdown), preliminary scorers will test the tracing time.
*When one round from two round is not completed, the record is summed up with the lowest lank record plus 1 second.
*When Tie is occurred, the faster one in the second game is a winner.
* Without the permission of the referee or working staffs, any team whose member touches the robot during competition will be disqualified.
