4. A Sensor Arm For Robotic Antarctic Meteorite Search - Chris Urmson; Ben Shamah; James P. Teza; Michael D. Wagner; Dimitrios Apostolopoulos; William Red Whittaker; William “red Whittaker
: In January 2000 the Nomad robot searched an area of blue ice in Antarctica and autonomously classified 5 in-situ meteorites. The robotic capabilities of search and target identification, coupled with the scientific capabilities of analysis and classification of rocks in an extreme environment were made possible by the integration of many different technologies for both hardware and software. This paper focuses on the development and integration of the sensor arm used to deploy a spectrometer from a multi-meter scale robot to centimeter scale rocks. The sensor arm combines off the shelf hardware for motion control, actuation, and sensing. Available...

15. The geophysical signatures and exploration potential of Australia's meteorite impact structures - Hawke, Philip James
[Truncated abstract. Please see the pdf version of the abstract for the complete text.] Thirty impact structures of confirmed or possible status are currently identified in Australia. Twenty-two of these structures are confirmed by the presence of meteorite fragments or shock metamorphic features that are diagnostic of meteorite impact. The remainder have an impact origin supported by strong secondary evidence. New impact structures are being discovered in Australia at a rate of about one every year, with geophysics a key tool in the identification of candidate structures for further investigation. It is estimated that between two and five times the...

16. The Gold Basin Meteorite Strewn Field - James Richardson
eless, evidence still remained of the initial ablation created fusion crust on portions of the stones. The next question to be answered was: where there more? Figure 2: Photograph of the Gold Basin area, west of Meadview, Arizona. The landscape is dominated by Joshua trees and Yucca plants, nestled amid the (usually) dry desert washes leading north to the Colorado River / Lake Mead. [courtesy http://www.ctaz.com/~rvpark/Meteorites.htm] Kriegh and Kring immediately set about organizing further expeditions to the Gold Basin region, with a team primarily composed of Jim Kriegh, John Blennert, and Ingrid Monrad. Over the course of the next few years, this team recovered more than 3000 meteorites from the...

18. Autonomous Robotic Meteorite Identification in Antarctica - William "red Whittaker,Liam Pedersen,Michael Wagner,Dimitrios Apostolopoulos
This paper describes the development and implementation of a Bayes network based system for distinguishing terrestrial rocks from meteorites from onboard the mobile robotic rover Nomad. Equipped with a color camera and spectrometer, Nomad autonomously made the first robotic identification of a meteorite, in January 2000 at the Elephant Moraine, Antarctica. This paper discusses rock classification from a robotic platform and the challenges of autonomously obtaining good sensor data in the field, while focusing on Nomad implementation.

19. Experimenter's Notebook: Robotic Search for Antarctic Meteorites 2000 Expedition - Michael D. Wagner
This document serves as an archive of expedition notes taken by Michael Wagner in January 2000 during the Robotic Search for Antarctic Meteorites expedition to Elephant Moraine, Antarctica. The culmination of a three year effort developing Nomad as a robotic explorer occurred when Nomad made the first meteorite discoveries by a robot. Through the use of autonomous science target recognition, Bayesian classification techniques and mission planning, Nomad classified meteorites while performing patterned searches. Three meteorites were autonomously found and classified and, in total, five meteorites were classified correctly throughout the expedition. A total of 42 samples were analyzed after 2500 m

20. Robotic Antarctic Meteorite Search: Outcomes - Dimitrios S. Apostolopoulos,Liam Pedersen,Benjamin N. Shamah,Kimberly Shillcutt,Michael D. Wagner,William L. Whittaker
: Automation of the search for and classification of Antarctic meteorites offers a unique case for early demonstration of robotics in a scenario analogous to geological exploratory missions to other planets and to the Earth's extremes. Moreover, the discovery of new meteorite samples is of great value because meteorites are the only significant source of extraterrestrial material available to scientists. In this paper we focus on the primary outcomes and technical lessons learned from the first field demonstration of autonomous search and in situ classification of Antarctic meteorites by a robot. Using a novel autonomous control architecture, specialized science sensing, combined manipulation and visual servoing, and Bayesian classification, the Nomad robot classified five...
