That show looks like a high tech version of Rockem Sockem Robots, it's quite a spectacle but not really the same as completely functional robots.
AI software, voice recognition and object recognition software is already quite advanced so that isn't the real issue.
Power source is the drawback in robot designs, those stage robots are not self contained they are powered and controlled externally. The LS3 Big Dog and the Legged Squad Support System are powered by an internal combustion engine which is a power source that probably wouldn't be practical for a household robot. Barring radical improvements in compact battery capacity, robots would not be operable for times long enough for them to be useful unless a compromise of the machines being tethered to the house by a power cord is considered acceptable. Future home designs might include electromagnetic transduction grids built into floors etc to power these machines, but then comes the health risks of constant exposure to electromagnetic fields to the homes living occupants.
The time for robots to be commonplace isn't too far off, but we aren't there yet and short of the development of a microreactor to power these things we still have a bit of waiting to do.
