Go to Post Spouting off without all of the facts is a bad idea. It's also bad to envoke the gods of "Gracious Professionalism" to judge others. - Rich Kressly [more]

Re: pic: Chassis Idea

Another electrical suggestion. Don't mount your gaming adapter down low in the frame especially that close to your high current victors and CIMs. You want the radio higher in the robot and away from sources of interference for optimal data transmission and minimal data loss.

I also agree that unless you have a very complicated robot, you'll likely only need one digital sidecar.

On wire size, the lower the AWG (American Wire Gauge) number, the larger the wire, more current carrying capacity, and lower resistance per foot resulting in lower voltage drop. Therfore, #6 is supplied in the KOP for your main power circuits, but you could use #4 and it would be legal. In cases where #16 is recommended you could use #14, 12, or 10 if you felt that voltage drop would be a significant issue and it would be legal. Just remember, larger wire is more weight, so unless you know you have a voltage drop issue, it's probably unnecessary.

Voltage drop is also directly related to efficiency. Voltage drop and wire resistance is Watts of wasted energy in heat. This can have a serious impact on battery performance when dealing with mechanisms which run at full power for long periods of time during a match. Vacuum venturis, high speed shooters and collector mechanisms are certainly worth watching for energy losses.

Keep thinking up new designs you're on the right track.
