The Katwijk beach planetary rover dataset [PDF]

open access: yesThe International Journal of Robotics Research, 2017
This paper describes a dataset collected along a 1 km section of beach near Katwijk, The Netherlands, which was populated with a collection of artificial rocks of varying sizes to emulate known rock size densities at current and potential Mars landing sites.

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.

Path-Following Control of Wheeled Planetary Exploration Robots Moving on Deformable Rough Terrain

open access: yesThe Scientific World Journal, 2014
The control of planetary rovers, which are high performance mobile robots that move on deformable rough terrain, is a challenging problem. Taking lateral skid into account, this paper presents a rough terrain model and nonholonomic kinematics model for ...

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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 ...

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.

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.
