The　good　jumping　stability　of　a　robot　prevents　the　robot　from　turning　over　in　the　jumping　process　and　is　the　basis　for　achieving　good　jumping　performance.　This　study　investigates　stability　assurance　for　a　locust-inspired　jumping　robot　from　the　perspective　of　mechanism　design.　A　mechanism　design　method　for　a　locust-inspired　robot　with　one-degree-of-freedom　jumping　leg　is　proposed　based　on　the　jumping　stability　mechanism　of　locusts.　Jumping　stability　includes　kinematic　and　dynamic　stability.　Kinematic　stability　focuses　on　the　attitude　change　of　a　robot　in　the　take-off　process　and　determines　the　dimension　of　each　link.　The　smaller　the　changes　in　attitude　are,　the　better　the　kinematic　stability　is.　Dynamic　stability　focuses　on　the　relationship　between　the　center　of　mass　position　and　the　total　inertia　moment.　The　smaller　the　changes　in　the　total　inertia　moment　are,　the　better　the　dynamic　stability　is;　that　is,　the　robot　has　a　low　tendency　to　turn　over　in　the　flight　phase.　Simulation　results　show　that　the　examined　robot　demonstrates　good　jumping　stability　when　the　developed　mechanism　design　method　is　used.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
