A New Paradigm for Planetary Exploration – the Mars Tumbleweed Rover
Introduction: The NASA Langley Research Center (LaRC) Mars Tumbleweed rover is a concept for a lightweight, spherical, deployable structure, with a configuration that maximizes drag to capture the Martian wind for mobility and extended mission duration. The wind-blown mobility of a Tumbleweed rover makes it an ideal platform for conducting distributed geophysical and meteorological surveys of b...
متن کاملAutonomous Rover Technology for Mars Sample Return
Planetary rovers enable good sample selection and retrieval for Mars sample return missions. After landing, the rovers search for the best possible scientific samples in the region around a lander, and they return these selected samples to an ascent vehicle that launches the samples into Mars orbit. To streamline the search for, the acquisition, and the retrieval of samples, rover autonomy is a...
متن کاملVisual wheel sinkage measurement for planetary rover mobility characterization
Wheel sinkage is an important indicator of mobile robot mobility in natural outdoor terrains. This paper presents a vision-based method to measure the sinkage of a rigid robot wheel in rigid or deformable terrain. The method is based on detecting the difference in intensity between the wheel rim and the terrain. The method uses a single grayscale camera and is computationally efficient, making ...
متن کاملPlanetary Rover Developments Supporting Mars Exploration, Sample Return and Future Human-Robotic Colonization
We overview our recent research on planetary mobility. Products of this effort include the Field Integrated Design & Operations rover (FIDO), Sample Return Rover (SRR), reconfigurable rover units that function as an All Terrain Explorer (ATE), and a multi-Robot Work Crew of closely cooperating rovers (RWC). FIDO rover is an advanced technology prototype; its design and field testing support NAS...
متن کاملParameter Identification of a Planetary Rover Wheel-Soil Contact Model via a Bayesian Approach
Soft soil contact models developed for planetary exploration rovers play an important role in the study of rover mobility. Nowadays, most of the existing contact models are based on Bekker theory which requires the evaluation of several soil parameters usually measured via bevameter tests. However, substantial differences existing between the plate-soil contact scenario and the wheel-soil conta...
