Well, you can build enormous and very strong structures out of Lego -
there are people who've built life-sized dinosaurs and such. With
enough Lego and careful construction, I have no doubt you could build
something that would carry 50 or 60 pounds.
Actually driving it along at any significant speed might need more than
2 motors, but that too is do-able if you have enough parts.
I don't think you'd have much difficulty moving 6 pounds over smooth,
level flooring with even the simplest construction.
