It captures human hand motion, tactile-glove data, and object motion during manipulation, then trains object-specific reinforcement-learning policies that reproduce the demonstrated motion using contacts the target robot hand can actually make. A real-time retargeter converts the human's live movements into a simulated robot-hand pose, synced with the tracked object, so the demonstrator sees where the robot would touch and can adjust their grip accordingly. Across four real-world tasks, this feedback loop raised real-robot replay success from 37.9% to 72.1%, and cut the time needed to collect each usable demonstration from 58.6 seconds to 18.2 seconds.\n\nRobot-hand data collection has long forced a choice between cheap human demonstrations that do not transfer well to hardware, and expensive robot-only demonstrations that transfer but do not scale. Showing the human a live preview of the robot's simulated contacts closes that gap without new hardware costs, and downstream policies trained on this data improved 29.1 percentage points over a visual-only baseline.\n\nThe simulated contacts matched real robot tactile readings only 44.2% of the time, a reminder that a preview is still a preview, not the real thing.","[\"robotics\",\"ai\",\"dexterous-manipulation\",\"teleoperation\"]","2026-09-23T04:00:00.000Z","2026-09-23T10:16:46.282Z","2026-09-23T10:16:51.377Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"The headline (and to a lesser extent the framing) inverts the actual mechanism — it's human demonstrators who watch a real-time overlay of the robot's simulated grip while they move their own hand, not robots watching or learning from their own hands autonomously; rewrite the headline\u002Fdek to make clear a human is doing the demonstrating and observing the robot's simulated contact feedback.","resolved","ai",[32,30,33,34],"robotics","dexterous-manipulation","teleoperation",[36],{"name":37,"url":38},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.24660",0,{"sections":41},[42,45,49,53,58,62,67,72,77,82,87,92,97,102],{"name":43,"slug":30,"count":44,"latest_published_at":18},"AI",4344,{"name":46,"slug":47,"count":48,"latest_published_at":18},"Security","security",713,{"name":50,"slug":51,"count":52,"latest_published_at":18},"Policy","policy",370,{"name":54,"slug":55,"count":56,"latest_published_at":57},"Deals","deals",206,"2026-09-23T09:43:46.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":18},"Hardware","hardware",169,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Science","science",134,"2026-09-23T09:00:00.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Consumer Tech","consumer-tech",110,"2026-09-22T20:00:00.000Z",{"name":73,"slug":74,"count":75,"latest_published_at":76},"Software","software",81,"2026-09-23T09:56:13.000Z",{"name":78,"slug":79,"count":80,"latest_published_at":81},"Dev Tools","dev-tools",79,"2026-09-22T22:21:13.000Z",{"name":83,"slug":84,"count":85,"latest_published_at":86},"Startups","startups",65,"2026-09-22T22:06:48.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"Gaming","gaming",45,"2026-09-22T15:35:06.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"General","general",43,"2026-09-21T23:48:56.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"Reviews","reviews",27,"2026-09-22T13:00:00.000Z",{"name":103,"slug":104,"count":105,"latest_published_at":106},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
