For a functional work-machine, I tend to favor simplicity of design.
This design requires the control of an operator, and for simplicity's sake, I didn't want to have the machine try to balance itself. "Balance" is this situation means not falling over, in the same manner as a fork-lift truck.
Rather than have extra weight for stability, I set it up that all lateral motions would be accomplished by transferring weight from one tripod of legs to another tripod of legs. I call this an insectoidal gait.
It is accomplished by having one tripod of legs follow the motions of the operator's right leg, and the overlapping tripod of legs following the motions of the left leg.
At no point can the device tip over.
For those new to the Undead Thread, not tipping over is a bigger issue that one might imagine at first. Quite a few of us find perpendicularity a challenge!
Now where's that floor come from?
