From the rules:

7. Materials This rule is not just about the robot... This rule controls everything you bring from the pit area to the competition area including the robot, all attachments, and all strategic objects when viewed all at once as a package. All these objects must be made entirely of LEGO elements in original factory condition (except LEGO string and tubing may be cut to length), and must conform to the following quantity limits on electrical parts, no matter what you intend to use or connect or attach to the robot at any one time:

For RCX users:        For NXT users:

RCX controller (1)   NXT controller (1)

motors (3)    motors (3)

touch sensors (2)    touch sensors (2)

light sensors (2)      light sensors (2)

lamp (1)       lamp (1)

rotation sensors (3)          rotation sensors (3 minus the number of NXT motors present)

3rd touch OR light sensor (1)      ultrasonic sensor (1)

Hi all;

Last year there was an email sent out that had a list of what is allowed for the NXT and RCX at the table. How many motors, sensors, etc. are allowed for each machine. I seem to have cleaned out my files and can no longer find that email – and have not been successful at locating the information on line – can someone send out that information?? This is our second year of participation – last year we had one team using the NXT  - this year I will have at least two teams one of which will be using the RCX. Please help……thank you.
