This is true, but it’s also assuming the robot has to be human shaped. A robot with 4 extendable arms and a gyroscopically balanced cabinet in its chest wouldn’t have too much trouble with that task.
How many other tasks is it not suited for now though? If we wanted a device to automate limited specific tasks then we don't need advanced highly advanced robotics. A human has strength, dexterity, high balance, very sensitive tactile touch, can move both fast and slow, is very compact, etc. A robot has to have serious tradeoffs just to hit two of those things. A robot arm that is capable of threading a needle is likely not suited to chopping some wood or carrying groceries. And if you just add a bunch of different arms for different tasks it becomes way more complex, expensive, heavy, and inefficient.
