POMDPs for Autonomous Science Exploration
Daniel Guirguis, Nathan Wallace, Hanna Kurniawati +1
Autonomous exploration missions require decision-making under sensor uncertainty and computational constraints, yet integrating scientific representations into POMDP planning has r…
Learning Safety-Guaranteed, Non-Greedy Control Barrier Functions Using Reinforcement Learning
Minduli Wijayatunga, Nathan Wallace, Salah Sukkarieh +1
Spacecraft rendezvous and proximity operations (RPO) pose safety risks to high-value assets, so formal safety guarantees are critical. Yet conservative safety controllers can reduc…
Automated Testing of Spatially-Dependent Environmental Hypotheses through Active Transfer Learning
Nicholas Harrison, Nathan Wallace, Salah Sukkarieh
The efficient collection of samples is an important factor in outdoor information gathering applications on account of high sampling costs such as time, energy, and potential destr…
Experimental Evaluation of a Hierarchical Operating Framework for Ground Robots in Agriculture
Stuart Eiffert, Nathan D. Wallace, He Kong +2
For mobile robots to be effectively applied to real world unstructured environments -- such as large scale farming -- they require the ability to generate adaptive plans that accou…
Resource and Response Aware Path Planning for Long-term Autonomy of Ground Robots in Agriculture
Stuart Eiffert, Nathan D. Wallace, He Kong +2
Achieving long-term autonomy for mobile robots operating in real-world unstructured environments such as farms remains a significant challenge. This is made increasingly complex in…
A Hierarchical Framework for Long-term and Robust Deployment of Field Ground Robots in Large-Scale Farming
Stuart Eiffert, Nathan D. Wallace, He Kong +2
Achieving long term autonomy of robots operating in dynamic environments such as farms remains a significant challenge. Arguably, the most demanding factors to achieve this are the…
Receding horizon estimation and control with structured noise blocking for mobile robot slip compensation
Nathan Wallace, He Kong, Andrew Hill +1
The control of field robots in varying and uncertain terrain conditions presents a challenge for autonomous navigation. Online estimation of the wheel-terrain slip characteristics…
