Previous　rolling　soft　robots　have　difficulty　in　balancing　the　locomotion　speed　with　energy　efficiency　and　have　limited　terrain　adaptability.　This　work　proposes　a　rolling　soft　robot　driven　by　local　snap-through　buckling,　which　employs　the　fast　response　and　configuration　maintenance　of　the　bistable　structure　to　enhance　the　locomotion　performance　of　the　soft　robot.　A　theory　based　on　bifurcation　and　the　energy　principle　is　established　to　analyze　the　rolling　mechanism.　The　influences　of　loading　position　and　geometric　parameters　on　the　rolling　performance　are　investigated　and　verified　experimentally.　The　soft　robot　shows　good　locomotion　speed　(0.95　body　length　per　second,　BL/s)　and　small　energy　loss　due　to　the　almost　unchanged　configuration　during　the　rolling　process.　The　soft　robot　adapts　to　complex　terrains,　including　a　step　with　the　height　of　15　mm,　a　slope　with　the　angle　of　18.36　degrees,　and　a　broken　bridge　with　the　gap　length　of　90　mm　(0.443　BL).　The　proposed　rolling　soft　robot　not　only　has　good　application　prospects　in　land　exploration　missions　and　medical　applications　but　also　provides　inspiration　for　the　development　of　rolling　soft　robots.
