Thanks for all the kind words, we were surprised nobody had ever built one before.
From my addition to the Dozer thread:
...For our promotional and testing projects we created what we call our "Universal Robotics Platform."
The URP was taking form to be a large, fast, and off road capable machine that we could use for football games to cover the field quickly while carrying a large payload (think t-shirt cannon/s). As it took it's final form, we naturally added a few blue panels and some eyes and got this:

"Dozer"
36" X 24" X 18"
195 lbs
Optima Red Top Battery
Four CIM Drive through CIMple Boxes
Geared for 32 ft/s to clear a football field in a hurry
Programmed speed defaults to 50% and requires driver input to reach full speed
10" Pneumatic wheelchair tires to handle offroad situations
Servo driven eyes
Almost FRC legal... and we still have to make his blade silver.
