Now storage chests are overpowered considering how early they appear. It would be better to clone them into new entities and then reduce capacity by 75% and logistic slots to say 2. Players will benefit from having an early logistics system, but at the same time it's not so good that it puts off players from researching better robots.
Also early roboports service the same area as vanilla ones. It would be better to make them support a much smaller area. Also charging efficiency should be lower than vanilla ones, meaning upgrading will reduce power usage. This too would mean early access, but still strongly encourage researching better logistic techs.
I'm not sure how easy/hard the game engine makes this, but it would be nice to right click on the robots in roboports to force it to only accept one type. Having just one slot for robots is problematic when construction robots decides it's ok to put 2 in each roboport while the logistic robots end up with nowhere to go.
