The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

A Comparison of Inverse Simulation-Based Fault Detection in a Simple Robotic Rover with a Traditional Model-Based Method [PDF]

open access: yes, 2017
Robotic rovers which are designed to work in extra-terrestrial environments present a unique challenge in terms of the reliability and availability of systems throughout the mission. Should some fault occur, with the nearest human potentially millions of

Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

Ultrasonically Assisted Hammer-Action Penetrators in Planetary Regolith [PDF]

open access: yes, 2018
This paper describes the effects of combining ultrasonic vibration with hammer-action style penetrators, such as the HP3 probe on the InSight mission. By synchronizing short pulses of vibration with the impact of the hammer, the number of hammer strikes ...

Aspirations and Apprehensions: Reconciling Youths' Desires and Concerns for a Sustainable Future

open access: yesSustainable Development, EarlyView.
ABSTRACT Although youth are widely acknowledged as change agents, their full participation is often limited by immediate concerns. This study examines how young people's aspirations shape their engagement with sustainability amid economic, environmental, and social uncertainties. Drawing on a large‐scale international survey (n: 15,076) and multinomial

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

open access: yesSmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

The History and Ideas of George Herbert Mead's Pragmatism and Its Relevance for Operational Research and Systems Thinkers

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without
