Possible robot advancements
>fixing their shitty designs
Why do the quadbots have no ranged weapons? Why do the Naver-types have their most powerful weapon mounted on their head so they need to bend over to actually use it? And why do they use Happy Missiles with the most unaerodynamic shape possible? There's so much improvement they could get out of just not being terrible.
>dedicated aircraft
The robots don't seem to have any proper aircraft and instead rely on their mechs, which will naturally perform worse in the air than a machine designed solely for aerial warfare. If they did things like build actual bombers then hid them above the cloud layer and went to town on natural enemies they would be doing a whole lot better.
>actual artillery
We've never seen them properly use long-ranged artillery (only what looks like short ranged missiles from the turtles) despite being technologically advanced. Even IRL artillery platforms can target enemies hundreds of kilometers away. The robots should be doing even better
>nukes
Nuff said
>nanomachines
Grey goo, disassembler warheads, better manufacturing, artificial plagues, in-combat replication, self-repair, converting destroyed machines into new working ones, etc
>smart matter
Imagine machines that can shapeshift to have more or less melee, better armour, stealth, speed, or whatever depending on the situation
>specialization
We've seen no machines specialized in fighting x or y enemy, only generalists. If i were Mother I'd focus on having some smaller armies dedicated to fighting certain enemies alongside my generalist forces.
