Hub for the wheel, machined by Rob Purdy. It splits in half and clamps onto
the shaft. Even still it wasn't enough to hold on to the shaft, and slipped
during testing. I solved the problem by drilling a hole through it all and
putting in a spring pin.

Death By Translation is a 30 pound featherweight bot.
This is my first bot that I have built as a team effort. Rich Olson has
spent years developing this concept in smaller weight classes, so I
approached him about doing the electronics for a larger bot. He stepped up
and put a lot of effort into DBT, developing a new custom board for it and
special software tweaks.
The bot has only one tooth. The tooth is 1/2" S7 tool
steel and weighs 2 pounds!
Outer ring welded. This ring is made of 1/8" 4140 steel. The holes around
the outside teeth allow the tooth to be mounted at different locations to
accommodate damage or adjust balance.
Rich's custom board in its protective enclosure.
Onboard is an accelerometer rated for 200 Gs and a Pololu microcontroller.
The accelerometer measures the G-forces and figures out the rpm. The Pololu
then figures out the proper time to turn the motor and LEDs on and off.
The S28-150 Magmotor is mounted with clamp-style
mounts. The red stuff is adhesive-backed rubber to absorb some of the impact
