Survival of Bacillus subtilis endospores on ultraviolet-irradiated rover wheels and Mars regolith under simulated Martian conditions.

Endospores of Bacillus subtilis HA101 were applied to a simulated Mars Exploration Rover (MER) wheel and exposed to Mars-normal UV irradiation for 1, 3, or 6 h. The experiment was designed to simulate a contaminated rover wheel sitting on its landing platform before rolling off onto the martian terrain, as was encountered during the Spirit and Opportunity missions. When exposed to 1 h of Mars U...

Study on grouser mechanism to directly detect sinkage of wheel during traversing loose soil for lunar exploration rovers

The rovers, which some researchers and agencies are developing, have many functions to sense a lot of information from peculiar environments like the lunar surface for localization, path planning and so on. On rough terrain, without artificial ground maintenance, like the lunar surface, the rovers avoid obstacles by using sensors, which they have. However, if the rovers traverse loose soil, lik...

Terramechanics-based Analysis and Control for Lunar/Planetary Exploration Robots

Surface mobility using wheeled mobile robots (Rovers) is one of the important technologies for lunar/planetary exploration missions. The rover in these missions significantly expands the exploration area and thus increases the scientific or programmatic return from the mission. These planetary exploration rovers are expected to travel long distances and perform complex tasks in order to fulfill...

Terramechanics-based model for steering maneuver of planetary exploration rovers on loose soil

This paper presents analytical models to investigate the steering maneuvers of planetary exploration rovers on loose soil. The models are based on wheel-soil interaction mechanics, or terramechanics, with which the traction and disturbance forces of a wheel are evaluated for various slip conditions. These traction forces are decomposed into the longitudinal and lateral directions of the wheel. ...

Simulating Mars Science Laboratory Curiosity Rover Traverses Using Artemis

Introduction: Curiosity has been traversing across the northern plains of Gale Crater since August 2012 and on 1/6/17 (Sol 1571) has traveled over ~15 km (based on wheel odometry). The rover is approaching a prominent hematite-bearing ridge, which it will ascend to make measurements, thereafter continuing south up the slopes of Mount Sharp. Curiosity has already encountered multiple mobility is...
