It has lidar to sense obstacles and MEMS sensors to sense its orientation, but I('m not sure hoiw extensive its obstacle avoidance algorithms go. It has "reflex" algorithms in firmware for quick reactions that keep it upright and stable, but I believe it needs extensive specialized programming to properly operate in specific environments performing specific task. And you can tell its reflexes to not keep it from harming humans like a co-robot by the wyt that the guy with the hockey stick makes sure he is no where near Atlas when it is operating.

Thanks for the explanation,

Agreed, the movement and stability is a great achievement in itself.

I also noticed that there were giant barcodes on the boxes and on the wall next to the door, as well as on the door.

That is another interesting point in terms of the control of the movement. Partially visual, distance control, on the other hand, plotted path through the forest. Can it recognize a tree, or another obstacle? So, of you put an obstacle suddenly in the way, does it move around it?

Is the control unit for that logic in the robot, or remote?

Yes, they have to specifically program tasks, but at a high level. For instance, his jaunt through the woods was plotted by a human, but the slipping and sliding to stary upright is part of his firmware. He can also pick up boxes--and chase them around for retrieval autonously from his firmware, but you have to program him to stack them on shelves and such--but at a high level (he performs the grasping and lifting and positioning from algorithms in his firmware. They intensionally made his actions appear all autonomous, like opening the door to take a walk in the fresh air--which a robot woulod never do on its own--in order to make his appear more human-like than he is. The important part of the video is his ability to stay upright and pick himsef up from fallling, which he previous generation could not do, but the rest depended on specific programming or path-plotting by a human. Still its a giant step forward from the old bigger clunkiret Atlas that was not that goog at unlevel ground and getting up after a fall.

So, how does it know:

- where the box is, and that it should pick it up?

- where it is supposed to go (though that door)?

- follow the human 

- walk where to in the forest (goal)?

Are these programmed actions, or part of a bigger "plan"?

How do you tell the robot, what its tasks are, and what does it do, for how long?

When a human gets up in the morning, there is a number of habits and a larger plan to follow (you would certainly hope for, with most people) which is gradually changing and evolving over time, so how do you define the tasks for the robot, and within which larger context and logical plan to follow?
