I saw this shortly after it came out. At the time I wondered if they were using hydraulics on Atlas. At one point you can see what looks suspiciously like some liquid was spilled on the floor. Looks like one of the robots sprung a leak during testing.

Incredible motion control. They've come a long way since Big Dog.

This is the best demo of  28-axis machine programming I'm ever seen. (yes,
28)  "Atlas has one large battery-powered motor and 28 hydraulic motors
with encoders.     The movement is controlled by a kind of g-code giving
the target locations then Atlas does his best to get there.

This is I think to date the best display of machine motion programming ever
