Numerical Efficiency of Inverse Simulation Methods Applied to a Wheeled Rover [PDF]

open access: yes, 2016
Extending the navigational capability of planetary rovers is essential for increasing the scientific outputs from such exploratory missions. In this paper a navigation method based on Inverse Simulation is applied to a four wheel rover.

Dynamic Simulation Tool Development for Planetary Rovers

open access: yesInternational Journal of Advanced Robotic Systems, 2008
A dynamic computer simulator was developed to study planetary rover mobility. The simulator was validated for step-obstacle negotiation by comparing simulation results with a quasi-static analysis of a rocker-bogie suspension.

TTA-GEP: Terrain Traversability Analysis with Geometry and Environmental Perception for the Path Planning of Planetary Rovers

open access: yesInternational Journal of Aerospace Engineering, 2023
Terrain traversability analysis (TTA), the key to the navigation of planetary rovers, is significant to the safety of the rover. Therefore, owing to its complexity, the Martian terrain is worth analysing comprehensively based on the terrain variability ...

VISION BASED OBSTACLE DETECTION USING ROVER STEREO IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Vision based obstacle detection using stereo images is an essential way for hazard avoidance and path planning in planetary rover missions. However, due to light condition changes and topographic relief, only partial or sparse three-dimensional points ...

Vision-Based Decision Support for Rover Path Planning in the Chang’e-4 Mission

open access: yesRemote Sensing, 2020
In planetary rover missions, rover path planning is critical to ensure the safety and efficiency of the rover traverse and in situ explorations. In the Chang’e-4 (CE-4) mission, we have proposed and developed vision-based decision support methods ...

Terrain mapping for a walking planetary rover [PDF]

open access: yesIEEE Transactions on Robotics and Automation, 1994
Presents a terrain mapping system for walking robots that constructs quantitative models of surface geometry, The accuracy of the constructed maps enables safe, power-efficient locomotion over the natural, rugged terrain found on planetary surfaces. The mapping system acquires range images with a laser rangefinder, preprocesses and stores the images ...

Dust, Sand, and Winds Within an Active Martian Storm in Jezero Crater

open access: yesGeophysical Research Letters, 2022
Rovers and landers on Mars have experienced local, regional, and planetary‐scale dust storms. However, in situ documentation of active lifting within storms has remained elusive.

Embedding a Scheduler in Execution for a Planetary Rover

open access: yesProceedings of the International Conference on Automated Planning and Scheduling, 2018
Scheduling often takes place in the context of execution. This reality drives several key design decisions: (1) when to invoke (re) scheduling, (2) what to do when the scheduler is running, and (3) how to use the schedule to execute scheduled activities.

Qualitative relational mapping and navigation for planetary rovers [PDF]

open access: yesRobotics and Autonomous Systems, 2016
This paper presents a novel method for qualitative mapping of large scale spaces. The proposed framework makes use of a graphical representation of the world in order to build a map consisting of qualitative constraints on the geometric relationships between landmark triplets.
