Rules were much different in 2002 but it was still one robot only.
1.2.2 Basic Gameplay

Each team competes using one team-built robot.

or in 2003 the WildStang rule...
M5 At the time of robot inspection, you must present all mechanisms that you will use on the robot during the entire competition event. It is acceptable, however, for a robot to play matches with a subset of the mechanisms that were present during inspection. Only mechanisms that were present during the inspection may be added,removed or reconfigured between matches. If subsets of mechanisms are changed between matches, the robot must still meet all inspection criteria. Robots must satisfy Rule M6 at all times.
