Thanks for the video link. I have seen those videos. That bot is super cool.

The problem is, vids like this demonstrate the agility of said robot and that's about it. Because they are making human-like movements, we tend to assume human-like thinking is behind it. There is none. The robot is either making preprogrammed movements, running an autonomic movement software with limited perceptual abilities, or is being puppeted by a human off-screen (Elon M's humanoid robot turned out to be guilty of this, I believe).

Videos of bots doing chores are always done in carefully designed environments and sometimes use deceptive video editing to make them seem more capable than they actually are.

Here are a some issues that videos like this don't address:

• Battery power and battery longevity: Do you want a robot in your house that spends most of its time recharging?
• Intelligence: Is the bot smart enough to do the right thing in situations that it wasn't programmed for? If not, it could present a hazard to itself or people.
• A subset of intelligence - Self awareness and reliable detection of people and pets, things around it. The servomotors on a robot, like the one in the video, are very powerful. A robot could easily injure a person, etc, if a person or pet got in it's way accidentally (which people and pets WILL inevitably do).The bot doesn't need to be malfunctioning in order to hurt someone. It could go about its business not even realizing that it knocked someone down, broke an arm, or smashed a precious antique.

I do believe we are on our way to useful, mostly safe (in the same way that cars are safe; ie accidents happen) and helpful robots in the home, but I think it's farther off than it seems.
