The capability of a robot infantry robot cannot be underestimated. It sure can be over-estimated, for its capability is truly infinite
Hundred companies, thousand engineers and inventers have tried advancing high-tech, but all stumble-stopped at a major block: a real capable actual robot that can do things, quickly enough, better than general humanoids.
It will, or may, take a team of brilliant scientist/philosopher/discoverer/inventer, to make this possible, with good-enough funding
A robot military arsenel class's capability in the battlefield truly is dictated (proportional to) by the artificial intelligence, plus the computer-to-hand-eye coordination, so to speaks. Robots should be more agile than the soon-to-be-very-obsolete infantry forces. So that at the lowest satisfactory threshold, so to speaks, its cheaper costs can cover up the lesser 1 to 1 combat capability value ratio
Here are several military robot classes we have planned out:
Light Guard
10kg
-aluminum body, aluminum and plastic in non-heat part
-fairly decent accuracy
-equals to one light-equipped infantry in some areas, for some duties
-limited duty proficiency
-operates like a turret, can set up strict curphews, no-man zones, and restriction areas
-battery lasts up to 6 hours or more (in usage)
-water proof, rain proof
-limited operational distance
-poor sight
Biggie
500kg
-rockets and dual-wield MGs
-Advanced AI 3.0 Pro
-walking legs or wheels
-fixated flamethrower if we may add (for fancy and dominance, appeal)
-alarm sound systems
-slow but strong, may get destroyed easily, but, it can strike from 200meter or more with incredible robot-cop accuracy
-Teamwork AI 2.5
-wireless communication capability
Skyrock
3kg
-gets launched into high air, auto finds target with camera, and heads there (dives down), delivery a grenade
-1 time usage
-gets over covers and trenches
-very cheap to produce
-identifies target (doesn't do it very well, but good enough for its cheap cost makes up for) (and in "good" locations, it's astonding - truly wow'ing )
-can be launched 3000 at a time
