> If there is a factory that allows a worker to step in front of a robot and depends on a wireless communication mechanism for safety, something is very very wrong.

All of those robots leave enough threshold to avoid collisions with other robots should they need to stop suddenly. The robots do on device calculations and report back their status to the central server to help other robots route around "damage" (stopped robots, for example). Instead, they give the robots general path instructions with enough buffer area to allow the robots to not trigger their own on device collision sensing. In the links that you gave, it's very clear that the robots do not depend on communicating with a central server if a worker steps in front of a robot.

By the way, in warehouses without such advanced protection, humans are _absolutely_ banned from the floor and it's treated like any other large industrial scale operation, including fail safes on gates (if gate is open, do not allow restart and human presence sensing (often through a badge of some sort).

Failure of this sort would lead to massive liabilities to the warehouse and robot owners. They are heavily incentivized to do things the right way. I'm not saying it's perfect, but it's actually quite advanced and safe.

And it has been that way for years.
