Robot Foundation Models transfer skills across different machines. Vision-Language Action models handle perception and control in a single system. Large Behavior Models generate human-like movement, Diffusion Policy Models produce smoother multi-step actions, and World Foundation Models simulate physics to generate training data. The authors show these pieces feed each other: World Foundation Models generate the training data that Vision-Language Action and Diffusion Policy models learn from, while Robot Foundation Models let those learned skills move from one robot body to another.\n\nThis matters because robotics has spent years chasing a GPT moment - a single model that generalizes the way large language models did for text. The survey's honest answer is that no such model exists yet; instead the field is stitching together five specialist approaches and hoping they compose well together. That's a more useful map for engineers than another company's demo reel, even if it makes for a less exciting headline.\n\nThe paper covers examples from self-driving cars to hospital robots and industrial and humanoid systems, and it flags data-efficient learning, sim-to-real transfer, edge-compatible hardware, and safety frameworks as unsolved problems - academic-speak for still years away from your local hospital floor.","[\"ai\",\"robotics\",\"foundation-models\",\"research\"]","2026-09-17T04:00:00.000Z","2026-09-18T02:00:28.633Z","2026-09-18T02:00:40.612Z","published",null,[],"ai",[24,26,27,28],"robotics","foundation-models","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.18111",0,{"sections":35},[36,40,44,49,54,58,62,67,72,76,81,86,91,96],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",3852,"2026-09-17T08:27:09.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",648,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",338,"2026-09-11T04:00:00.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":18},"Hardware","hardware",154,{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",114,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":73,"slug":74,"count":75,"latest_published_at":18},"Dev Tools","dev-tools",73,{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",41,"2026-09-08T01:57:23.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
