Low on soldiers is low on funding. It's all relative. Ukraine doesn't have nearly enough funding to make people care enough to fight. It certainly doesn't have enough funding to get people to be bothered building robots for it

But what if the robot dogs are ethnically Ukrainian, and they built themselves? Even if every man woman and child in Ukraine were killed, the ethnically Ukrainian nazi robot dogs could keep on fighting the war with NATO funding and targetting, with homages to Zelenskyy projected against piles of rubble that once were buildings while T2 robots rise from the ashes and join the new generation skynet-connected drone fleets to take out Russia. Russia has no chance against the Terminator! Ukraine wins!
(ok it is late, i'm just typing the next crazy word that pops into my head)
More seriously, as long as Ukraine refuses to talk to Russia, the fact that the war continues instead of settles somehow is now their doing isn't it? And that has been the case for a long time now. This is the main reason I don't see Ukraine as defending itself anymore.
This....this is what would happen.
