Maybe you can inspect us again. The kids enjoyed that inspection more than any other.

For the record...
<R54> All wires distributing power with a constant polarity (i.e., except for relay module, speed
controller, or sensor outputs) shall be color-coded as follows:
• Use red, white, or brown wire for +12 Vdc and +5 Vdc connections.
• Use black or blue wire for common (-) connections.

AND

<R50> The 12V battery, the main 120-amp circuit breaker, the power distribution block, and circuit
breaker distribution panels shall be connected as shown in the 2008 Power Distribution
Diagram. In particular:

• All circuit breaker distribution panels must be connected directly to the power
distribution block. No intermediate connections are permitted.

Not only does daisy chaining the power violate rules it is a bad idea, causing the voltage drop from your high current loads to lower the available voltage to the RC. Split your high current loads when possible.
As to the color code, my personal position is to use the color codes normally used in your area so that your students become accustomed to industry standards. Although brown and blue are european standards they are not in this country.
All teams should take note of the placement of the high current components such that #6 wire runs are short and direct.

Nice board. Simple and effective.

Please people read the post before writing your junk it is really annoying to read things twice or more. Like in this post about the PDB it has been said please no more i think they get the point.
