Although adhesion\u2010based wall\u2010climbing robots demonstrate stable climbing on smooth surfaces in outer space, there is scarce research on their stable adhesion on rough surfaces within a microgravity environment. A novel adhesive material is developed inspired by the adhesion mechanism and locomotion of the <jats:italic>Gekko<\/jats:italic> gecko. This material exhibits exceptional adhesion across various materials and surface roughness. A variable\u2010stiffness gecko\u2010inspired paw is engineered, generating substantial adhesion forces while minimizing detachment forces. Impressively, this paw generates up to 180\u2009N of adhesion force on smooth surfaces and achieves detachment without external forces. By integrating such variable\u2010stiffness paws with a wall\u2010climbing robot, a gecko\u2010inspired robot effectively operating in a microgravity environment is created. The robotic satellite surface climbing experiments and robotic satellite capture experiments are conducted using a simulated microgravity environment and a satellite model. The results unequivocally demonstrate the gecko\u2010inspired robot's proficiency in executing various functions, including stable motion and capture on both smooth and rough spacecraft surfaces within a microgravity environment. These experiments underscore the potential of adhesion\u2010based gecko\u2010inspired robots for in\u2010orbit services and spacecraft capture and recovery.<\/jats:p>","DOI":"10.1002\/aisy.202400043","type":"journal-article","created":{"date-parts":[[2024,10,22]],"date-time":"2024-10-22T01:00:29Z","timestamp":1729558829000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Gecko\u2010Inspired Robot Using Novel Variable\u2010Stiffness Adhesive Paw Can Climb on Rough\/Smooth Surfaces in Microgravity"],"prefix":"10.1002","volume":"6","author":[{"given":"Zhiwei","family":"Yu","sequence":"first","affiliation":[{"name":"The College of Mechanic and Electronic Engineering Nanjing University of Aeronautics and Astronautics  Nanjing 210000 P.
