But *mechanical* complexity would be lower
Ziggo has a frame that includes locomotion, and a spinning turret for a weapon. My design would have basically two moving parts: the drive motors[1].
How fast could it actually move? Let's suppose it spins 600 rpm. If, on each revolution, you could slow one wheel just enough, in a narrowly controlled portion of its rotation, to give a differential of about 1/4-inch in the distance the two wheels travel, that would give you about 1/8-inch worth of lateral motion, or 1 1/4 inches per second. Not fast, but certainly enough to pursue an opponent who didn't want to attack while you are at speed.
I still don't have any idea if there are electric motors that can do this kind of speed, and still have fine enough or fast enough control to do the pulsed braking.
[1] The simplist construction would be to have the wheels attached directly to the shafts, but the potential for un-fixable damage would be unacceptable. So the motor shafts would obviously use gears to drive the axles. A few more moving parts, but then there would be something to fix if an axle gets bent.
