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.

- lachlan_gray 3y agoSometimes 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?
- rotexo 3y agoI’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.
- QuercusMax 3y agoThe Tines are such a fascinating concept of how a pack intelligence could work. That whole universe has so many interesting ideas.
- CooCooCaCha 3y agoThat's because the robot has gone ultra instinct.
- williamcotton 3y agoIf 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.
- voxelizer 3y agoI 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.
- wantsanagent 3y agoThe 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.
- yosito 3y agoThis would make sense. If I'm tele-operating a robot, I'm going to be much less coordinated than if I just use my own two hands to hang a tshirt.
