The easiest would be to make a skid steer type 4WD wheeled platform.

It would drive on the concrete floor, maybe over extension cords and
such.

Any suggestions for something that would be a quality product and
capable of lasting up to 1,000 hours of use?


Ig, I built one once for doing robotics lectures that had a similar
quality of construction as you wish. I used wheels/tires designed for
hand-pulled golf bag carts. They're small enough to be managable in that
sort of platform, yet large enough in diameter to easily handle small
obstacles (up to about an inch high).

I don't know of any commercial ones, because I'm not in that aspect of my
electronics hobby now for over 18 years.
