FIRST documents
The 2009 FRC Suggestions is a great overview document on how to build a robot. This document talks about how to build the kit-bot frame, motors, electrical, etc. It's must reading for a rookie team, but is a great refresher for experienced teams.
Drive information
Fisher Price Motors
The Fisher Price Motor that they use for their Power Wheels product has been a staple in the Kit of Parts for the last few years. These links are good reference materials for the FP motor
FRC1189 2009 Shooter Gearbox Development is a comprehensive white paper on how they used the FP motors for their shooter. They show pictures of the internals of the gear train and show a number of different mounting techniques.
Power wheels driver hub can be used to connect wheels to the motor.
Tool Information
The spool tip for the MIG welder, Clarke Hot Shot Spool Gun, is KP11-30 (030) 0.8mm MAGNUM.
