Coordinated motion control model of a six-wheeled rocker lunar rover
Advances in Mechanical Engineering, 2016 At present, control methods of the six-wheeled rocker lunar rover primarily consist of setting the same driving parameters for each wheel. This type of control method ignores the multiple active driving characteristics of the lunar rover and causes ...
