Problems with Victor 884

[Al Skierkiewicz]

Alex,
Normally I suggest that speed controllers be mounted near the motors they are controlling to minimize the wire runs. There is nothing in the picture to prevent you from using perf stock or a piece of lexan on the uprights across the back of the robot. Then you can mount the controllers vertically on that. Since the Jaguars have mounting holes in the sides, you can use threaded standoffs to elevate every other one and using the standoffs, rotate the elevated controllers 90 degrees to allow you to stagger them and fit more in the space. That way, no fans are occluded and the wiring is spaced out. Also, mounting the controllers so that they are front to back rather than side to side, works well too. This allows them to be mounted next to each other and touching. The wiring works better that way as well and the only drawback is getting the PWM cables attached. In your actual robot, don't forget to mark your wires and controllers. You can get 3M wire marking tape from Digikey. It is expensive (about $30 for a dispenser with all 10 EIA colors) but is well worth it when you are trouble shooting.
