Most text-to-3D policies compress an instruction and its demonstration into one global embedding, which blurs instructions that are similar but behaviorally distinct. T3DP instead keeps the token-level structure of both the language and the robot's movements, linking specific words to specific segments of behavior. That representation then conditions a point-cloud-based 3D diffusion policy without changing its underlying architecture.\n\nAcross the Meta-World, ManiSkill, and RoboTwin simulation benchmarks, T3DP beat global alignment by 11.0 to 14.2 points on held-out instructions across all 15 task families, and on real robots it raised average success from 47.5% to 65.0%. That's a meaningful gap: most instruction-following policies grasp the gist of a command but not its fine print, which works for picking up a cup but breaks down when the exact distance moved is what matters.\n\nIt's still a benchmark result, not a warehouse robot, but it points at a real gap between language fluency and physical precision that bigger models alone haven't closed.","[\"robotics\",\"language-grounding\",\"manipulation\",\"ai-research\"]","2026-10-01T04:00:00.000Z","2026-10-01T23:04:20.101Z","2026-10-01T23:04:24.172Z","published",null,[],"ai",[26,27,28,29],"robotics","language-grounding","manipulation","ai-research",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.39599",0,{"sections":36},[37,40,44,48,53,58,62,67,72,76,81,86,91,96],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",5572,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",815,{"name":45,"slug":46,"count":47,"latest_published_at":18},"Policy","policy",430,{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",298,"2026-09-30T21:00:26.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",196,"2026-09-30T13:00:00.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",163,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",149,"2026-09-30T22:57:11.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Dev Tools","dev-tools",93,"2026-10-01T02:30:48.000Z",{"name":73,"slug":74,"count":70,"latest_published_at":75},"Software","software","2026-09-30T21:41:11.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",84,"2026-09-30T20:39:09.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",51,"2026-09-30T16:24:30.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
