Team will be allowed a maximum of 1 RCX OR NXT and ONLY Lego parts are allowed. Team will be allowed to UNLIMITED number of motors and sensors. Teams will be allowed to use ANY type of LEGO motor, sensor and parts. (Eg. Technic Motor)

General Rules 1.

Robot must follow the line and direction of turn.

2.

At any point of time, any part of the robot MUST be on the line.

3.

Should the robot run out of the line, it should be back to the line in 5 seconds. Failure to do so will result in a fault run.

4.

A robot's run ends when it has completed the course, or it is deemed by the judge to be unable to track the line.

5.

There will not be any penalty if any of the parts drop off on the playfield during the actual run. However, if it causes the robot being unable to continue racing, it will be considered as a fault run.

6.

There will be 30 minutes scheduled for trial runs at the beginning of the competition but timing will not be taken. (Schedule will be given on the day of competition)

7. There will be unlimited number of Actual runs for each team and the fastest time will be taken. (Schedule will be given on the day of competition) 8. The robot can be programmed before the competition but it is expected that the algorithm and diagram of the program will be available for review by the judges. The teams can bring their own portable computer, in order to re-load their program before their actual turn. The teams will be allocated some practice time in order to calibrate their sensors. Please note that lighting conditions might affect the algorithm so it will be necessary to determine on the day of the competition if you need to change the threshold values. 9. There is no restriction on the type of programming software used. (eg. NXT-G, Robolab, RobotC) 10. Decisions regarding whether a robot is tracking the course line are made only by a judge. 11. Judge's decision(s) is/are final.

Robot Inspection Robot will be inspected to meet all official requirements stated. Teams are allowed to make changes to robot after each run.
