Re: Does anyone have some sort of guide?

There have been a number of people who have recommended that you get and read thoroughly the electrical schematics for both the signal and power connections to the robot. I would completely concur.

The second point on wiring is to learn from the successes (or better the failures) of other teams. A connection to other teams (in the name of gracious professionalism) is vital for newer teams.

One thing not mentioned here (but there are posts here on CD that have gone over this) is the physical aspects of the electronics. Making sure the battery connections are kept reasonably short. Locating the power switch in a good visible and easy to find place. Keep the PDB central and the motor controller wires short and direct. Use quick disconnects (we prefer the Anderson Power Poles like many teams) for your motor connections to make it easy to disconnect.

Other things.
- Label everything (you won't remember which is the pwm for which controller, or was this one for the spike?)
- Work to keep the wires neat and orderly. Helps keep you organized.
- Watch your wire gauge, connector size and wire color
- Verify (multiple times) your motor count and type against the FIRST rules.
- Keep a spreadsheet of each motor used: type, use, controller, connections, and other necessary information.
- Work with the software team to plan the Digital and PWM port usage.

I am sure there are many other things, but this is a start.

Enjoy!
