The self driving robots have to have facilities specifically constructed and/or configured with the constraints of the robotic system in mind. No one makes a go anywhere, do anything self navigating robot.

The application of robotics in industry is still very much more akin to industrial automation than it is true autonomy. There's a ton you have to take into account to design a system that works well. In practice, this means that traditional automation is typically still the better solution than full autonomy.
