A systematic approach to reliably characterize soils based on Bevameter testing [PDF]
, 2010 Although there exists a lot of information about soil parameter identification in literature, currently there is no algorithm both making use of state of the art identification methodologies and incorporating statistical analysis.

Embedding a Scheduler in Execution for a Planetary Rover
Proceedings 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]
Robotics 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.

Decision-Theoretic Control of Planetary Rovers [PDF]
, 2002 Planetary rovers are small unmanned vehicles equipped with cameras and a variety of sensors used for scientific experiments. They must operate under tight constraints over such resources as operation time, power, storage capacity, and communication bandwidth.

Advanced Robotics Research, EarlyView.A sea turtle‐inspired amphibious robot uses simulation‐guided optimization to adapt its flipper coordination to different environments. Sensitivity analysis and multiobjective Bayesian optimization identify terrain‐dependent controllers that are validated on hardware.

Experimental research of planetary rover entrapment on sandy terrain
Results in EngineeringTrafficability of wheeled rovers on loose and rough terrain is essential for planetary exploration missions. Existing studies mainly focused on wheel–soil interaction modeling, terramechanics simulation and motion control, yet full-vehicle experimental ...

Robotics in Ionizing Radiation Environments: Vulnerabilities, Hardening, and Future Directions
Advanced Robotics Research, EarlyView.Radiation exposure causes cumulative degradation in robotic sensors, actuators, and electronic logic, often leading to undetected failures. This study maps component vulnerabilities, evaluates hardening and shielding strategies, and identifies testing gaps that must be addressed to enable next‐generation radiation‐tolerant robotic systems.
