It's complicated, and a lot of work to put a list like that together, which is why I haven't yet. but basically, every aspect of a robot is upgraded in some small way, speed, health, carry capacity... And a Robochest has a single charging point, no expansion to the grid, but lots of space for robot...

I can't seem to find a description of the items and what they do.
Like for instance, what benefit do i get with Robots MK2,3
What is the point of the Robo Chests vs normal Robo ports. etc....
