There's something odd about the way the arms move, like they are two distinct entities cooperating rather than being part of one coordinated mind. Maybe this is an example of the uncanny valley, or maybe it's because they are two physically separate arms, but it seems to me like one arm moves while the other waits for its turn. It's as if engineers programmed them to work sequentially. I wonder if it might be beneficial for engineers to study videos of humans doing these tasks and try to mimic those movements rather than trying to program a sequential procedure.
Now I'm trying to imagine how our limb movements might be perceived by a creature that natively evolved the style of coordination in the video :) it would be "weird" but how might they describe that weirdness and what might underlie it in us..?
If you monitor your own movements you’ll find plenty of sequential procedures. The big difference with how these robot arms move is that they are firmly planted on a large table, whereas your arms attached to this self-balancing, lightweight gyrating torso.
The policy is trained from human demonstrations. When you're teleoperating a robot you tend to "not do anything" with the arm you're not actively focusing on unless you need to do bi-manual operations.
Sometimes I feel this about myself... I don't think much to walk or do something with both hands, they work stuff out on their own. How much do my legs or hands understand about each other?
I feel we tend to coordinate movements to balance ourselves, specially with arms. In this case, the arms are independent from each other and are each firmly fixed to the table.
I’ve been reading Vernor Vinge’s A Fire Upon the Deep where that is a characteristic of one of the species in the novel, and had the exact same thought.
