I cut out and shaped all the tires. They're cut out of a sheet of 3/8" 70A polyurethane rubber (which was insanely expensive).
|I first started with strips, then cut 45 deg angles on the ends.|
|I tried wrapping a tire around the wheel and holding it with zip-ties.|
|Unfortunately, I need more coverage to hold the gap closed.|
Shielding sensor wires:
I bought some sweet 5 conductor shielded wire off of ebay. It's kapton coated, which is a nice feature.
|Replaced the green mess of wires.|
|I can't open the motors anymore without significant effort, so I just spliced wires.|
|The shield is connected to the sensor ground.|
I mostly finished the Wii Nunchuck wireless controller (Shane did the electronics and programming...Thanks Shane!)
|It's ugly, I know. I need to figure out a different package. I was too optimistic thinking that I could jam it in the nunchuck.|
I soldered a little copper sheet to the 5V regulator (center) on the boards because they get pretty hot.
The MOSFET package on the left (no heatsink) is going to be removed, along with most of the components on MC3.
And that's about it for now. I'm not planning on gluing tires until we resolve these controller issues- they're what's holding up progress at the moment.
