Most social navigation research assumes a robot already has a fixed destination and just needs to get there without bumping into people. This system instead starts with a natural-language description, like pointing a robot toward a group having a conversation, and has it identify the right people in a scene, then predict a pose that fits how humans naturally arrange themselves around queues, conversations, or audiences. The method uses recursive spectral partitioning to generate candidate groupings and a language-conditioned image-geometry model to rank them, then applies human-formation priors to map out feasible joining positions. The team tested it on conversations, queues, and audiences of varying sizes and crowd densities, and validated it on a real robot in both static and shifting group settings.\n\nThis matters because the boring part of robotics, standing in the right place, is often harder than the flashy part. A robotic guide dog or autonomous mobility scooter that can plan a route but then hovers awkwardly at the edge of a group is still a failure for the person relying on it. Reading group formation from language is also a step toward robots that take instructions the way a person would give them to another person, not through coordinates or waypoints.\n\nIt is a narrow, unglamorous problem, which is probably why it is worth taking seriously: sub-second inference and real-robot tests suggest this is closer to deployable than performative.","[\"robotics\",\"ai\",\"social-navigation\",\"human-robot-interaction\"]","2026-09-24T04:00:00.000Z","2026-09-24T07:36:24.416Z","2026-09-24T07:36:34.801Z","published",null,[],"ai",[26,24,27,28],"robotics","social-navigation","human-robot-interaction",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.28467",0,{"sections":35},[36,39,43,48,53,58,63,68,73,78,83,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":18},"AI",4424,{"name":40,"slug":41,"count":42,"latest_published_at":18},"Security","security",724,{"name":44,"slug":45,"count":46,"latest_published_at":47},"Policy","policy",380,"2026-09-23T22:53:43.000Z",{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",227,"2026-09-24T11:08:33.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",174,"2026-09-24T10:10:29.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":62},"Science","science",136,"2026-09-24T09:00:00.000Z",{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",116,"2026-09-24T00:51:49.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Software","software",85,"2026-09-23T20:00:00.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Dev Tools","dev-tools",79,"2026-09-22T22:21:13.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Startups","startups",66,"2026-09-23T17:28:38.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Gaming","gaming",45,"2026-09-22T15:35:06.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",43,"2026-09-21T23:48:56.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",27,"2026-09-22T13:00:00.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
