Journal of Field Robotics, 2(1), (2022): 1351–1385, https://doi.org/10.55417/fr.2022045.In this report, we present the system design, operational strategy, and results of coordinated multivehicle field demonstrations of autonomous marine robotic technologies in search-for-life missions within the Pacific shelf margin of Costa Rica and the Santorini-Kolumbo caldera complex, which serve as analogs to environments that may exist in oceans beyond Earth. This report focuses on the automation of remotely operated vehicle (ROV) manipulator operations for targeted biological sample-collection-and-return from the seafloor. In the context of future extraterrestrial exploration missions to ocean worlds, an ROV is an analog to a planetary lander, which must be capable of high-level autonomy. Our field trials involve two underwater vehicles, the SuBastian ROV and the Nereid Under Ice (NUI) hybrid ROV for mixed initiative (i.e., teleoperated or autonomous) missions, both equipped seven-degrees-of-freedom hydraulic manipulators. We describe an adaptable, hardware-independent computer vision architecture that enables high-level automated manipulation. The vision system provides a three-dimensional understanding of the workspace to inform manipulator motion planning in complex unstructured environments. We demonstrate the effectiveness of the vision system and control framework through field trials in increasingly challenging environments, including the automated collection and return of biological samples from within the active undersea volcano Kolumbo. Based on our experiences in the field, we discuss the performance of our system and identify promising directions for future research.This work was funded under a NASA PSTAR grant, number NNX16AL08G, and by the National Science Foundation under grants IIS-1830660 and IIS-1830500.

Rover and Telerobotics Technology Program

The Jet Propulsion Laboratory's (JPL's) Rover and Telerobotics Technology Program, sponsored by the National Aeronautics and Space Administration (NASA), responds to opportunities presented by NASA space missions and systems, and seeds commerical applications of the emerging robotics technology. The scope of the JPL Rover and Telerobotics Technology Program comprises three major segments of activity: NASA robotic systems for planetary exploration, robotic technology and terrestrial spin-offs, and technology for non-NASA sponsors. Significant technical achievements have been reached in each of these areas, including complete telerobotic system prototypes that have built and tested in realistic scenarios relevant to prospective users. In addition, the program has conducted complementary basic research and created innovative technology and terrestrial applications, as well as enabled a variety of commercial spin-offs

CIS-lunar space infrastructure lunar technologies: Executive summary

Technologies necessary for the creation of a cis-Lunar infrastructure, namely: (1) automation and robotics; (2) life support systems; (3) fluid management; (4) propulsion; and (5) rotating technologies, are explored. The technological focal point is on the development of automated and robotic systems for the implementation of a Lunar Oasis produced by Automation and Robotics (LOAR). Under direction from the NASA Office of Exploration, automation and robotics were extensively utilized as an initiating stage in the return to the Moon. A pair of autonomous rovers, modular in design and built from interchangeable and specialized components, is proposed. Utilizing a buddy system, these rovers will be able to support each other and to enhance their individual capabilities. One rover primarily explores and maps while the second rover tests the feasibility of various materials-processing techniques. The automated missions emphasize availability and potential uses of Lunar resources, and the deployment and operations of the LOAR program. An experimental bio-volume is put into place as the precursor to a Lunar environmentally controlled life support system. The bio-volume will determine the reproduction, growth and production characteristics of various life forms housed on the Lunar surface. Physicochemical regenerative technologies and stored resources will be used to buffer biological disturbances of the bio-volume environment. The in situ Lunar resources will be both tested and used within this bio-volume. Second phase development on the Lunar surface calls for manned operations. Repairs and re-configuration of the initial framework will ensue. An autonomously-initiated manned Lunar oasis can become an essential component of the United States space program

Coring Planetary Ices; Their Thermomechanical Behaviour

Spacecraft missions are underway that will mechanically probe the material found at the surface of cometary nuclei. Little is known about the physical properties of these bodies and how their surface material will respond to a probe's sampling mechanisms. Tools such as rotating drills or hammering bits can cause the otherwise pristine material to be damaged and heated. This work addresses the phenomenon of tool-induced heating and examines the properties of ices in three planetary environments in which such coring processes may occur. A unique drilling system has been built to provide data on the thermal response of ices under space-like conditions. Cold (-150 K) samples of water ice and carbon dioxide ice have been formed from the vapour phase and cored with an instrumented cutting head under low pressures. The effort used to core these ices has been measured as a function of temperature, coring speed, and depth rate. Three broad conclusions can be drawn from these experiments. 1) Carbon dioxide ice grown from its vapour at 150 K requires approximately one third of the mechanical effort needed to core or drill the same volume of water ice at a given rate at the same temperature. 2) The power needed to drive a coring tool through water ice at a fixed rotation speed and a given vertical rate trebles as the ice's temperature falls from 240 to 140 K. Specific cutting energies greater than 55 J m-3 have been recorded for ice at 140 K, and dense carbon dioxide at the same temperature has been shown to have one half of that strength displayed by water ice. 3) Mechanical effort is mostly converted into heat in a coring process. Temperature rises of at least 10 K have been measured in dense samples of cryogenic (-140 K) carbon dioxide ice around a coring tool that operated with power levels of no more than 2 W. For the same applied power, water ices are expected to display one third of this temperature rise seen when coring void-free carbon dioxide ice at the same temperature. The magnitude of this heating effect is assessed for a comet sampling tool on the Rosetta comet lander. It is expected that temperature rises of a few degrees will occur in water-ice rich material retrieved by the tool if the comet, at depths of several tens of centimetres, shows little porosity. It is also suggested that higher temperatures will be developed by extracting material from greater depths, where carbon dioxide may be present as a void-free ice

Workshop on Advanced Technologies for Planetary Instruments, part 1

This meeting was conceived in response to new challenges facing NASA's robotic solar system exploration program. This volume contains papers presented at the Workshop on Advanced Technologies for Planetary Instruments on 28-30 Apr. 1993. This meeting was conceived in response to new challenges facing NASA's robotic solar system exploration program. Over the past several years, SDIO has sponsored a significant technology development program aimed, in part, at the production of instruments with these characteristics. This workshop provided an opportunity for specialists from the planetary science and DoD communities to establish contacts, to explore common technical ground in an open forum, and more specifically, to discuss the applicability of SDIO's technology base to planetary science instruments

The <i>Castalia</i> mission to Main Belt Comet 133P/Elst-Pizarro

We describe Castalia, a proposed mission to rendezvous with a Main Belt Comet (MBC), 133P/Elst-Pizarro. MBCs are a recently discovered population of apparently icy bodies within the main asteroid belt between Mars and Jupiter, which may represent the remnants of the population which supplied the early Earth with water. Castalia will perform the first exploration of this population by characterising 133P in detail, solving the puzzle of the MBC’s activity, and making the first in situ measurements of water in the asteroid belt. In many ways a successor to ESA’s highly successful Rosetta mission, Castalia will allow direct comparison between very different classes of comet, including measuring critical isotope ratios, plasma and dust properties. It will also feature the first radar system to visit a minor body, mapping the ice in the interior. Castalia was proposed, in slightly different versions, to the ESA M4 and M5 calls within the Cosmic Vision programme. We describe the science motivation for the mission, the measurements required to achieve the scientific goals, and the proposed instrument payload and spacecraft to achieve these

Development and Evaluation of a Tool for EVA or Robotic Planetary Sampling

NASA's current plans call for humans to return to the Moon by 2020 and eventually travel to Mars. The primary rational for this undertaking is scientific exploration and discovery, especially in the area of geology. These missions will include both human and robotic explorers. In order to be successful, these human/robot teams will need specialized tools for geologic sampling and analysis. This thesis discusses a proposed multi-purpose tool for planetary sampling useful for researching surface exploration strategies for humans and human-robot teams. Previous planetary science missions were analyzed to define set of requirements for a sampling tool. From this, a concept was conceived and a prototype constructed. Various soil and rock samples were taken to verify the concept and requirements. The tool performance was tested against known soil models. The end result is a set of sampling requirements, a proven concept for a tool, and proposed future development and research
