Robot introspection through learned hidden Markov models [PDF]

open access: yes, 2006
In this paper we describe a machine learning approach for acquiring a model of a robot behaviour from raw sensor data. We are interested in automating the acquisition of behavioural models to provide a robot with an introspective capability.

Vision-based navigation and guidance for small Mars UAVs

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Mars airplane is one of the candidate payloads of JAXA's next Mars exploration program. Airborne observation of Mars is expected to fill the “gap” between rovers, which provides a detailed observation but a limited area of coverage, and orbiters ...
