Inspired by the agility of cats, we investigate the role of forelimbs in the landing process. By identifying the kinematic chain of the cat skeleton and tracking it using animal posture estimation, we derive the cushioning strategy that cats use to handle landing impacts. The results indicate that the strategy effectively transforms high-intensity impacts into prolonged low-intensity impacts, thereby safeguarding the brain and internal organs. We adapt this cushioning strategy for robotic platforms through reasonable assumptions and simplifications. Simulations are conducted in both gravitational and zero gravity environments, demonstrating that the optimized strategy not only reduces ground impact and prolongs the cushioning duration but also effectively suppresses the robot\u2019s rebound. In zero gravity, the strategy enhances stable attachment to target surfaces. This research introduces a novel biomimetic control strategy for landing control in the on-orbit operations of space robots.<\/jats:p>","DOI":"10.3390\/biomimetics9110691","type":"journal-article","created":{"date-parts":[[2024,11,13]],"date-time":"2024-11-13T06:23:16Z","timestamp":1731478996000},"page":"691","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Analysis of Cushioned Landing Strategies of Cats Based on Posture Estimation"],"prefix":"10.3390","volume":"9","author":[{"given":"Li","family":"Zhang","sequence":"first","affiliation":[{"name":"Research Center of Aerospace Mechanism and Control, School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150080, China"},{"name":"Space Structure Mechanism Technology Laboratory, China Aerospace Science and Technology Group Co., Ltd., Shanghai 201109, China"},{"name":"Zhengzhou Research Institute, Harbin Institute of Technology, Zhengzhou 450000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangliang","family":"Han","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering and Automation, Beihang University, Beijing 100083, China"},{"name":"Aerospace System Engineering Shanghai, Shanghai 201109, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haohang","family":"Liu","sequence":"additional","affiliation":[{"name":"Research Center of Aerospace Mechanism and Control, School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Shi","sequence":"additional","affiliation":[{"name":"Research Center of Aerospace Mechanism and Control, School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meiyang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Research Center of Aerospace Mechanism and Control, School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-4626-735X","authenticated-orcid":false,"given":"Weijun","family":"Wang","sequence":"additional","affiliation":[{"name":"Shanghai Institute of Aerospace System Engineering, Shanghai 201109, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6798-6113","authenticated-orcid":false,"given":"Xuyan","family":"Hou","sequence":"additional","affiliation":[{"name":"Research Center of Aerospace Mechanism and Control, School of Mechatronics Engineering, Harbin Institute of Technology, Harbin 150080, China"},{"name":"Space Structure Mechanism Technology Laboratory, China Aerospace Science and Technology Group Co., Ltd., Shanghai 201109, China"},{"name":"Zhengzhou Research Institute, Harbin Institute of Technology, Zhengzhou 450000, China"},{"name":"Songjiang Laboratory, Harbin Institute of Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1109\/MAES.2021.3114057","article-title":"Microgravity performance evaluation for zero gravity robot in China\u2019s space station","volume":"37","author":"Liu","year":"2022","journal-title":"IEEE Aerosp.
