Researchers trained three types of sequence models — LSTM, GRU, and Transformers — on time-series proprioceptive sensor data. The best model hit 91.11% accuracy during live testing. The team also found that a sliding window approach to preprocessing outperformed other strategies for this kind of time-series task.\n\nIn shared workspaces where robots and people operate side by side, identifying what a robot arm is actually touching matters for safety. Prior systems could only classify contacts as soft or hard — useful, but not enough when a human hand and a foam block feel similar. A three-class model that specifically flags human contact adds a layer of precision that safety systems need before any of this leaves the lab.\n\nNinety-one percent accuracy is a solid number on a controlled dataset; whether it survives messier real-world conditions — novel objects, varied contact angles, different body parts — is the question papers like this rarely get to answer.","[\"robotics\",\"human-robot-interaction\",\"machine-learning\",\"safety\"]","2026-06-30T04:00:00.000Z","2026-06-30T14:19:54.391Z","2026-06-30T14:19:57.123Z","published",null,[],"ai",[26,27,28,29],"robotics","human-robot-interaction","machine-learning","safety",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2508.02425",0,{"sections":36},[37,41,46,51,56,61,66,71,76,81,86,90,95,100],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":87,"slug":88,"count":84,"latest_published_at":89},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
