Planetary Rover Mobility
Research Guide
What is Planetary Rover Mobility?
Planetary Rover Mobility studies wheel-soil interactions, suspension systems, and control algorithms for rovers traversing regolith on Mars and the Moon.
Research covers rocker-bogie suspensions, wheel designs with grousers, and terramechanics modeling for low-gravity environments (Asnani et al., 2009; 116 citations). Key works analyze traction control (Yoshida et al., 2006; 40 citations) and path-following on deformable terrain (Ding et al., 2014; 18 citations). Over 10 listed papers span 2005-2023, focusing on simulant testing and slip estimation.
Why It Matters
Optimizations in wheel design from Asnani et al. (2009) enable Lunar Roving Vehicle traversal of loose regolith, directly informing Mars rover missions like Zhurong (Zhang et al., 2022; 22 citations). Traction control models by Yoshida et al. (2006) improve autonomy on rough terrain, reducing mission risks in polar cold traps as in Bartlett et al. (2008; 35 citations). Path-following algorithms by Ding et al. (2014) enhance exploration efficiency, supporting sample collection for exobiology (Anttila, 2005; 48 citations).
Key Research Challenges
Wheel Slip in Loose Regolith
Rovers experience high slip on fine-grained, low-cohesion soils like lunar regolith, complicating odometry and path planning. Zhang et al. (2022) developed data-driven slip estimation for Zhurong rover, achieving accurate models from wheel-terrain data. Yoshida et al. (2006) proposed terramechanics-based traction control to mitigate slip in planetary rovers.
Low-Gravity Terramechanics Modeling
Standard Bekker-Wong models fail in lunar 1/6g conditions, requiring microgravity validation. Ozaki et al. (2023) conducted granular flow experiments on ISS using artificial gravity generators. Suzuki et al. (2019) compared RFT with DEM for grousered wheel analysis on regolith simulants.
Path Control on Deformable Terrain
Lateral skid and nonholonomic constraints challenge precise navigation on uneven regolith. Ding et al. (2014) integrated rough terrain models with kinematics for path-following control. Guo et al. (2023) advanced hexapod gait planning to address lunar soil adhesion and corrosiveness.
