Moreland, Scott J, 2022, "Diagonal grousers improve turning performance in skid-steer rovers", https://doi.org/10.48577/jpl.SURPXS, International Society for Terrain-Vehicle Systems, JPL Open Repository
Skid steering is a popular choice for planetary rover missions due to its simplicity, low cost, and low mass compared to explicit steering systems. Skid steer rovers’ wheels do not turn explicitly; vehicle turning is achieved by driving the left and right wheels at different velo... |
