Researchers trained six versions on three LIBERO-Spatial manipulation tasks and evaluated them over 540 held-out rollouts across three seeds. Conditioning the model on real object and goal geometry produced 28.9% success, worse than the 36.7% achieved when those same geometric signals were shuffled at random during training, and only slightly better than the 24.4% baseline with no geometry at all. A separate approach using timing signals instead of spatial coordinates scored just 11.1%, with one run failing to converge entirely.\n\nThe result cuts against a common assumption in embodied AI: that giving a model accurate, structured information about its environment should make it more reliable, not less. It also points to a deeper generalization problem: a robustness test in the same paper found a policy using relative coordinates held onto 7 of 10 successes when its reference frame changed, while every vision-based policy tested collapsed to 3 successes or fewer out of 20 after the target object moved just 5 centimeters.\n\nIn an industry racing to bolt language models onto robot arms, a paper showing the 'obvious' engineering choice doesn't even beat noise is a useful reality check.","[\"robotics\",\"embodied-ai\",\"language-models\",\"ai-research\"]","2026-09-11T04:00:00.000Z","2026-09-11T09:44:57.145Z","2026-09-11T09:45:09.098Z","published",null,[],"ai",[26,27,28,29],"robotics","embodied-ai","language-models","ai-research",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.09213",0,{"sections":36},[37,40,44,48,53,58,63,66,71,75,80,85,90,95],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",3543,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",637,{"name":45,"slug":46,"count":47,"latest_published_at":18},"Policy","policy",338,{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",153,"2026-09-09T15:12:32.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":62},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":64,"slug":65,"count":61,"latest_published_at":18},"Science","science",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":18},"Dev Tools","dev-tools",70,{"name":76,"slug":77,"count":78,"latest_published_at":79},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"General","general",41,"2026-09-08T01:57:23.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
