I've been meaning to put this up for a while, so here it is.
The first bot I worked on was a 15 pound wedge called Fer 'Merica.
I don't have many pictures of it, but here's a video of a rumble at the 2013 NRL nationals; it was one of the first times I drove, since technically it wasn't my bot (We do this through our school, Proctor High School, so it's kinda weird sometimes), even though I did nearly all the work on it.

I've still got one of the wedges, here's where it took a few hits.

The next year, we decided to retire GTO and G6, the two beater bots in that video.
I set out to make a new one, and started with this guy, which I called Uprising.

1/8" TI armor all around, sliding wedges, 4 wheel drive, and a 6" diameter weapon.
I completed an early version with steel armor and no weapon a while back, here's a picture of it with Proctor's other bots for this year lined up. Weapon is one of the ones off of GTO just for mock up purposes.

Here's the electronics, but mostly, a look at the armor.
Wiring is nasty because it's from last years bot and I haven't bothered to clean it up for the shorter distances on this bot.

These are the new Ti armor pieces, before I milled them to the exact sizes and hole locations, and the weapon, also rough cut on a waterjet.

Here's the weapon mounts and weapon motor.

Cross brace, slots into the weapon mounts, bolts to the bottom, armor, and top plates.

I've done some more work since these pictures, I finished the wheel mounts and a new top plate, and I'm starting to countersink the Ti, but I burnt up my last shitty countersink, so I'm waiting on some nice ones.
