Each BRUTE had two fixed wheels at the rear and two swivelling caster wheels at the front, with polyurethane tyres and taper bearings. [1] Coupling were at front and rear, the front being a pin, the rear a hinged loop on a sprung shaft. A lever on the front operated brakes on the rear wheels and lifted the coupling pin.
At the time, the fifth wheel literally was a wheel that moved with the trailer—unlike today’s technology that secures a kingpin.

Omni wheels or poly wheels, similar to Mecanum wheels, are wheels with small discs (called rollers) around the circumference which are perpendicular to the turning direction. The effect is that the wheel can be driven with full force, but will also slide laterally with great ease. These wheels are often employed in holonomic drive systems.
