It's still too expensive vs the gained utility. Given a tradeoff of very expensive and finnicky hardware, vs offroad wheels, use animals, or just pay humans, the robot loses. A big part of that cost is the drive train and transmission. You need low speed and tons of torque, so this usually means geardowns. Not that the software NRE costs are trivial, but they can be amortized. But building even a single basic six axis arm with human comparable strength is gonna cost several grand.
