Does it though? I agree with what your saying that it will make the game easier for smaller groups using them, but it would also allow larger orgs to expand more. Secondly the main problem with mining robots is that they would be able to gather huge amounts of resources 24/7, whereas any automated ship will be weaker than player ships ("Weapons, when scripted, will be extremely inefficient or underpowered compared to unscripted weapons used by players (for example by limiting number of actions per second achieved by the script). This is to make the game more balanced" Dual Universe Wiki on LAU scripting). But it would allow smaller organisations who don't have members of larger organisations to defend their territory 24/7 to have some protection from pirate raids. In addition while they would be able to build structures quicker with construction bots, they would still need the resources to do so, hence they would not be able to build the same structures as larger organisations.
In my previous comment I probably should've specified this, as while these wouldn't make smaller organisations equal to larger organisations, they could still compete in the sense of being able to complete projects like building a space station at least near to the speed in which larger organisations can.
Lastly, life of a larger organisation will not be made worse by additions of battlebot, construction bot, etc. Considering the large amount of resources they have to deal with, these would be very useful as battlebot's could be used as fighters like vulture droids, transport bots would help these larger organisations manage and transport their enormous quantities of resources a lot easier, and construction bots would allow them to complete huge projects a lot easier.
In summary I probably shouldn't have said that small organisations will be able to compete with larger organisations, just that it would certainly benefit smaller organisations a lot.
