Abstract To ensure the safety and efficiency of Zhurong Mars rover when climbing a slope on Mars, forces under four methods, which are normal climbing, Z‐type diagonal bionic wriggle analyzed. Each method corresponds to different maximum slopes. The experiments carried out with backup dense soft terrains determine range for methods. According slope, peak current, cost transport, state terrain, strategy is given. For terrains, soil cohesive 0.99 1.4 kN/m n +1 friction modules 1528 700 +2 , respectively. Specifically, recommended low‐range slopes, while or suggested medium‐range found be optimal high‐range rover, it fails if critical values exceeded. These results provide valuable insights human operators planning rover's slope‐climbing actions Mars.
