And yet, there are no robot soldier there yet as a chance to make Ukraine win. Robotics is still very much in its infancy, meaning a lot of potential, but robots don't have enough situational awareness, are not silent enough, don't have enough battery, rendering legged robots useless. Even drones still need to be connected to a central server. There are no drones doing edge AI, meaning they are very much susceptible to electronic warfare, breaking the link.
Robot soldiers don't look like humans for the same reasons that bulldozers don't look like Shaq holding a shovel.
Robots that would win the Ukraine war would look like a barrage of drones or missiles (either stealthy or in overwhelming numbers) flying into the air defence radars. There are 100m-wide radio dishes in orbit, the exact location and type of every radar on earth is known. Followed by standoff hammering with precision artillery (both the guns and the shells are fundamentally robotic) and lots more drones and missiles.
The this hasn't happened seems more a question of not revealing capabilities the US feels it might one day need as a trump card. Combined with not wishing to aggravate things to much (they say) or, cynically, not wishing to let the war end until the Russians are bled dry. Don't want them to capitulate while still in possession of anything more advanced than a Mosin-Nagant.
