I think I'll enter, with the one bot that even possibly immobilized a robot: Minesweeper.

Minesweeper

Shape: Tornado (S6)
Colour: Silver, with MINESWEEPER written on the sides in red.
Dimensions: 90cm x 85cm x 25cm
Drive: 2x 36v LEM-130 motors, powered by 6x NiCad Battlepacks. The motors power the 2 middle wheels.

Speed: 20mph
Ground Clearance: 0mm at front and back due to scoops, and 5mm at sides.
Turning Circle: 0m
Weapon: 2 Hardox snowplow-like scoops that can move slightly vertically, like Behemoth's, so I get good pushing power, but 0mm ground clearance at front and back.
Srimech: Invertible
Strengths: Super-reliable and fast. Now more maneuverable.
Weaknesses: Not too much of an offensive weapon.
