Rebuilt Caster mounting bracket

I rebuilt the caster mounting bracket for the new frame mounting.  Its much more sturdy now for sure.  I will remove the hinge pin on the lids maybe to make access easier.  With this new frame arrangement, I'm considering moving the controls on the lid up to another enclosure on the next level.  Ugg.  I have to do this anyways for the metal detector controls, so I guess i can move the others.  This will make the bottom strictly power, batteries, and motor drives.

On another note, it looks like the cheap Harbor Freight caster isn't going to work very well. I guess I'll look into using those pillow blocks I bought way back.  They might be better for the swivel.

I also noticed my video was lagging quite a bit lately.  Not sure if its the GPS daemon causing the issue or not.  I'm guessing its a file access bottleneck to the SD card.  Two ways to approach it if that is the case - use a separate non-video Pi for the GPS, or remove the onscreen video.

I also weighed the bot with the added framing.  It weighs in at 282 lbs...
