The device uses two coiled elastic rods that store energy when twisted and release it in a sudden snap to drive each jump. Researchers say the snapping mechanism could inspire compact, fast-moving robots for navigating rough terrain.","why":"A newly published demonstration of a simple elastic snap mechanism enabling fast, frog-like hopping has caught attention among robotics and physics enthusiasts.","tone":"neutral","entities":["University of Michigan","UCLA"],"summarized_at":"2026-10-08T16:23:17.146804Z","meta":{"tag":"physics","via":"scan","kind":"status","lang":"en","instance":"mastodon.social","tag_uses":59},"nw":null,"promo":null,"kind":null,"importance":null,"hidden":false,"hide_reason":null,"judged_at":null,"title_en":"Twisting elastic rods power a leaping frog robot","section_name":"Technology","category_name":"Technology","timeline":[{"captured_at":"2026-10-08T10:05:14.856351Z","rank":2,"volume":5},{"captured_at":"2026-10-08T10:12:15.737852Z","rank":1,"volume":5},{"captured_at":"2026-10-08T10:12:15.737852Z","rank":8,"volume":5},{"captured_at":"2026-10-08T10:14:13.325781Z","rank":1,"volume":5},{"captured_at":"2026-10-08T10:16:13.747125Z","rank":6,"volume":5},{"captured_at":"2026-10-08T10:21:14.432477Z","rank":2,"volume":5},{"captured_at":"2026-10-08T11:34:14.757737Z","rank":1,"volume":6},{"captured_at":"2026-10-08T11:34:14.757737Z","rank":7,"volume":6},{"captured_at":"2026-10-08T11:38:14.573383Z","rank":5,"volume":6},{"captured_at":"2026-10-08T11:43:16.152505Z","rank":2,"volume":6},{"captured_at":"2026-10-08T12:57:02.884938Z","rank":7,"volume":6},{"captured_at":"2026-10-08T12:57:02.884938Z","rank":1,"volume":6},{"captured_at":"2026-10-08T13:01:00.587477Z","rank":5,"volume":6},{"captured_at":"2026-10-08T13:06:25.010710Z","rank":2,"volume":6},{"captured_at":"2026-10-08T14:19:25.056655Z","rank":7,"volume":6},{"captured_at":"2026-10-08T14:19:25.056655Z","rank":1,"volume":6},{"captured_at":"2026-10-08T14:23:24.197641Z","rank":4,"volume":6},{"captured_at":"2026-10-08T15:41:26.220890Z","rank":7,"volume":6},{"captured_at":"2026-10-08T15:41:26.220890Z","rank":1,"volume":6},{"captured_at":"2026-10-08T15:45:24.360441Z","rank":4,"volume":6}],"posts":[{"platform":"mastodon","url":"https://fediscience.org/@tksst/117404585233244712","author":"tksst@fediscience.org","title":null,"snippet":"🐸 NEW: Engineers at the University of # Michigan and # UCLA found that twisting a coiled elastic rod stores # energy that releases in a sudden snap.
