For a bit of context there are some classically very hard things going on in this video, so if you're not impressed, be glad you didn't have to try to build this 10 years ago.
- Coordinating two hands
- Mobile body
- Deformable objects
- Thin affordances (bag zip in particular)
- Multi-object single grasp
Really a host of things that had individually been tackled as either perception or manipulation problems and probably led to more than one person's PhD here on HN.
