Teams participating in the NRC 2007 RCX Category Event must use the LEGO® MindStorms for School Team Challenge sets (any colour is acceptable as long as it is from the 9794 series) in the competition.
Teams are to observe the following:
1 RCX (NXT is NOT allowed in RCX Category Event), 3 motors (5225), 3 light sensors, 2 touch sensors and 1 angle sensor are allowed.
The teams must use the ROBOLAB (any version) as the official programming language for the RCX Category Event.
The dimensions of the robot must not exceed 250mm × 250mm × 250mm in size (including any extended part after any automatic transformation), including installed batteries.
All teams should bring their own competition kits, computers, batteries, adaptors and any other items that they need for the competition. Teams should not use any flammable materials as part of their design.
Teams are allowed to pre-program the robot or store the program inside the laptop before the competition.
All teams must use AA batteries with a total output voltage not exceeding 9V.
The team is not allowed to modify any part of the competition kit and the ROBOLAB software such as the motor, RCX, sensor and Firmware. If the judges detect any changes in the competition kit, the team will be disqualified automatically.
Competition Field: The Competition Field Maps illustrated in the rules are for demonstration only. Before the competition, the NRC Organisation Committee will provide SEVERAL competition fields with different variations that are allowed by the rules for teams to practise and test their robots.
Only the operator of the competing team is allowed into the match area during the match.
Miss-tracking: A robot is declared “miss track” when all its wheels are on the same side of the track line. Miss-tracking will result in immediate disqualification from the match for the robot concerned (but not necessarily for its opponent).
Miss-colouring: A robot is declared “miss colour” when it fails to do specific tasks associated with a colour patch. “Miss colouring” will result in the immediate disqualification from the match for the robot concerned (but not necessarily for its opponent).
Team members and the mentor / teacher must not intervene or interfere with the operation of the robot of their own team or that of the opponents, physically or remotely. Interference will result in an immediate disqualification.
Robots: The Robots designed for the NRC 2007 RCX Category event must be autonomous robots. Teams are given 1 hour and 30 minutes before the competition in Round 1 to build and test their robots. During Round 1, robots must be built from scratch (all the parts must be apart). Thus, pre-built robots are not allowed in the competition area. In subsequent rounds, teams may modify the robots they built in Round 1. Once the competition starts, team members are not allowed to touch their robot again.
Inspection: After the 1 hour and 30 minutes preparation, robots will be quarantined at a specific area for detailed inspection of materials used. Once the robots are placed in the quarantine area, teams are not allowed to touch their robots until it is their turn to compete.
Objections: Teams are expected to obey the competition rules to maintain an orderly and friendly competition. In the event of a valid objection, teams must fill in and submit the objection form to the Head Judge to settle the dispute within the shortest time possible. The Head Judge and referees have the ultimate authority during the National Robotics Competition. Their decisions are final. Referees will not review recorded replays after the match is over.
Competition Venue: In the quarantine area of the RCX Category competition, only the students and organizers are allowed. No teachers and/or parents can enter the restricted area.
The competition kit and/or construction materials, particularly of the winning teams, will be randomly checked at the end of the competition.
In the event of a conflict in the translation of the rules, the English version is considered the correct and final version.
