You can control the number of items delivered to the network at the point of entry and keep them in storage chests. Use belts or trains to bridge separate networks together for those items you need near your defenses (walls, turrets, repair packs, etc.). This has several advantages, especially that any construction robots will always stay close to the things they need to repair (instead of being used to construct stuff in your factory). This works a bit better with just Vanilla bots, since roboports don't have output signals specific to the different types of Angel's bots, but it still works with Bob's or Angel's bots.You can design your factory and defenses such that you use a separate logistics network to cover your defenses. if the number of available logistic robots drops below 10, add more.Ĭombine this with inserter arm hand-overs between adjacent logistic networks in a some type of chain linking back to where you make your bots and now you've got a self balancing system for supplying your entire base and automatically scaling up your robot supply as your base grows (scaling down is harder, but why would you ever do that?). I also set requester chests and inserter arms feeding in for each type of robot that I want to maintain on the network, with similar logic conditions on the inserter arm like enable if X < 10, i.e. available_logistic_bots > some minimum threshold you'd like to maintain for the network. Set filter inserters for each type of robot you want to catch, and if you wire it to the roboport, you can set conditions like 'only pull a logistic robot off the roboport if Y > 100, i.e.

There's still no magic trick I know of to summon all your robots with the exception of some meticulous deconstruction regimen, but this method tends to be pretty effective at catching robots over time. It doesn't matter that much where you put it, but placing it around a high-traffic path is best, since you'll tend to get more robots landing there.

I copy 1-2 instances of this in each independent logistic network I build. My preferred method is to have a blueprint for a 'robocatcher and load balancer.' Something like what's shown below. Your construction robots will do this job, and then park themselves in the nearest roboports. Order deconstruction of those requester chests.Your logistic robots will do this job, and then park themselves in the nearest roboports. stone or coal you mined before building on top of the deposit). In the unused area, make many requester chests with large requests of something you have stockpiled (e.g.Set up inserters to extract robots from the area(s) where you keep your storage chests, and an unused area nearby.You can encourage robots to stop in particular roboports by creating a very large jobs which will be finished in the vicinity. This can be used to collect the stragglers automatically in the long run, but requires you to make a change at every roboport whenever you get a new upgrade. (As Vyndicu's answer already mentioned, but for completeness:) For any given roboport, you can use filter inserters to extract specific types of robots. The laborious but complete option would be to do a rolling shutdown of your logistics network: starting from one edge, remove roboports, and then put them back but making sure the old network and the new network never touch, and the new network contains no old robots. I'm not familiar with what might be available with Angel's and Bob's, but this is what comes to mind from vanilla.
