The invention discloses an independent drive steering system of a six-wheel rocker arm unmanned lunar rover, which mainly comprises a steering mechanism, a driving mechanism and wheels. A walking system of a middle wheel does not comprise a steering system. The steering mechanism comprises an upper steering motor sleeve, a lower steering motor sleeve, a steering motor, a steering planetary gear accelerator, a bidirectional thrust ball bearing sleeve and a sealing ring. The driving mechanism comprises left and right motor sleeves, a driving motor, a driving planetary gear accelerator, an angular contact ball bearing and a clamping ring. The wheels are matched with the wheel baffle rings. The design process comprises the following steps of 1, designing parameters of a driving system motor and a planetary gear accelerator reducer, 2, designing parameters of a steering system motor and the planetary gear accelerator reducer, 3, determining the size and assembly relationship of the motor sleeve, 4, designing the structure of the wheel, 5, realizing structural design of a steering system, 6, conducting structural design of a driving system and wheels, and 7, conducting system sealing design.
