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. |

Re: pic: Chassis Idea
OK,
Electrical guy checking in...As Art and Jim have pointed out, you want to increase the size of your wire. Robot rules for many years have specified #6 minimum for all primary wiring. i.e. battery to main breaker to power distribution. Although robot rules allow for #12 for devices fed from 40 amp breakers we use and recommend #10. You can use the battery as counter weight so be ready to move it as needed. The power distro is better suited in the center of the robot. It is in this way that wire runs are minimized and balanced between the two sides of the robot. I can't tell you how many teams have come to me complaining they can't get the robot running straight when they have six feet of wire feeding the motors on one side and six inches of wire feeding the other. Although someone suggested to point the battery contacts down, I don't recommend this. Our high current applications will cause some venting from time to time and you (and the robot inspector) can't see if the terminals are getting into trouble when the battery is mounted that way. Remember that the sidecars do not pass a lot of current so they may be placed almost anywhere. I am suspecting a change in radios so don't dedicate yourself to that size package but do plan on getting it up out of the metallic clutter. In addition to the noise, there is significant reflections of RF down among the metallic parts. |

Re: pic: Chassis Idea
That you everyone for all the help!
Every bit of it has been taken into consideration. (On the wires.. The largest I can get is 8 gauge... Does anyone know how to make Inventor make 6 or 4 gauge wires?) |

Re: pic: Chassis Idea
you have to create your own style for it or you can be lazy and just change the size of the segment.
