Objects are carried by UGVs, they can carry 200-300 kilograms while being pretty small, small UGVs can carry up to 100 kilos with size of ~1m in every dimension. Unless you can explain to a very expensive and smart robot what you need to rotate and where and how to operate tools given, you'll need a very competent pilot for these robots which with high probability would still be worse than dumbest of humans because they lack agility and require a lot of supportive infra to operate. Rich nations probably would try to make humanoid robots (like they did with robodogs) with questionable success.
