For most things they don't need to be "human equivalent." I'd be willing to be the current crop of robots we're seeing could do most tasks like vacuuming, cooking, picking up clutter, folding laundry and putting it aways, making beds, touch up painting, gardening etc. It seems to be getting better very fast. And if mechanical tendons break, you replace them. Big deal. You don't even need a person to do the repair.
