Boston Dynamics' Atlas Strikes Again

05/11/2018 9:27 AM

Yesterday, Boston Dynamics posted a video of their Atlas robot running outdoors:

My only gripe is that they didn't include bloopers like last year's video:

Interesting that Atlas swings its arms just like a human. I thought that the strength of arm motion helped propel the body along. Couldn't/wouldn't a robot have legs that were strong enough without the arm motion?

It's just too spooky to watch.

Purely speculation

Makes sense. The arm movement is remarkably fluid and human-like.

It's conservation of angular momentum. Running without swinging the arms would twist the torso. Swinging the arms in the opposite direction creates an equal and opposite torque. It's the most efficient way to run for a robot as well as a human.

I agree with you, these things are spooky. I think it's because they don't have heads.

Better noisy than having one sneak up on you.
