Electrical Information

General Electric

Robot Electrical Design is a link to a presentation that Al Skierkiewicz gave this spring on Robot Electrical Design. It covers a wide variety of information that should be considered during the design process. (1 hour)

PSOC

PSOC carrier board pin outs This is the board made by e-Stop Electronics to make it easier to make connections.

Jaguar

[Jaguar home page] Links to information about both the Gray and Black Jaguar speed controllers.

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.

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.
