SPHERES Interact - Human-Machine Interaction Aboard the International Space Station
SPHERES Interact - Human-Machine Interaction aboard the International Space Station Enrico Stoll Steffen Jaekel Jacob Katz Alvar Saenz-Otero Space Systems Laboratory Massachusetts Institute of Technology 77 Massachusetts Avenue, Cambridge Massachusetts, 02139-4307, USA [email protected] [email protected] [email protected] [email protected] Renuganth Varatharajoo Department of Aerospace Engineering University Putra Malaysia 43400 Selangor, Malaysia [email protected] Abstract The deployment of space robots for servicing and maintenance operations, which are tele- operated from ground, is a valuable addition to existing autonomous systems since it will provide flexibility and robustness in mission operations. In this connection, not only robotic manipulators are of great use but also free-flying inspector satellites supporting the oper- ations through additional feedback to the ground operator. The manual control of such an inspector satellite at a remote location is challenging since the navigation in three- dimensional space is unfamiliar and large time delays can occur in the communication chan- nel. This paper shows a series of robotic experiments, in which satellites are controlled by astronauts aboard the International Space Station (ISS). The Synchronized Position Hold Engage Reorient Experimental Satellites (SPHERES) were utilized to study several aspects of a remotely controlled inspector satellite. The focus in this case study is to investigate different approaches to human-spacecraft interaction with varying levels of autonomy under zero-gravity conditions. 1 Introduction Human-machine interaction is a wide spread research topic on Earth since there are many terrestrial applica- tions, such as industrial assembly or rescue robots. Analogously, there are a number of possible applications in space such as maintenance, inspection and assembly amongst others. -

EVALUATION OF FLIGHT CONTROL TECHNIQUES USING VIRTUAL REALITY IN AN ARTIFICIAL GRAVITY ROTATING ENVIRONMENT A Thesis by ROBERT DALLAS HOGAN Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Gregory Chamitoff Committee Members, Nancy Currie-Gregg Kristi Shryock Head of Department, Rodney Bowersox August 2019 Major Subject: Aerospace Engineering Copyright 2019 Robert Dallas Hogan ABSTRACT The purpose of this thesis is to develop a collaborative virtual reality (VR) engineering platform for space system and mission design and to demonstrate its utility in the context of evaluating human interfaces for future control systems. Much of the work for this project was the development of the platform itself (called SpaceCRAFT). Additionally, a user study was done with 33 subjects to examine the potential advantages of designing and testing systems in virtual environments that otherwise may be difficult to replicate on Earth. The task evaluated was flying a drone in a rotating artificial gravity environment, which involves numerous unfamiliar forces. Different control strategies were tested using VR in comparison to flat screen interfaces. This particular challenge was chosen to emphasize the difference between immersive and non-immersive environments, and the results demonstrate that VR is a promising tool for human-interface system design and evaluation. The 50-meter radius space station simulated an open-air, long-term habitable environment and was designed with considerations of human factors for rotating reference frames. A quadrotor control model was developed and simulated a variety of stabilization and sensitivity modes. -
Critical Systems
Critical Systems ©Ian Sommerville 2004 Software Engineering, 7th edition. Chapter 3 Slide 1 Objectives ● To explain what is meant by a critical system where system failure can have severe human or economic consequence. ● To explain four dimensions of dependability - availability, reliability, safety and security. ● To explain that, to achieve dependability, you need to avoid mistakes, detect and remove errors and limit damage caused by failure. ©Ian Sommerville 2004 Software Engineering, 7th edition. Chapter 3 Slide 2 Topics covered ● A simple safety-critical system ● System dependability ● Availability and reliability ● Safety ● Security ©Ian Sommerville 2004 Software Engineering, 7th edition. Chapter 3 Slide 3 Critical Systems ● Safety-critical systems • Failure results in loss of life, injury or damage to the environment; • Chemical plant protection system; ● Mission-critical systems • Failure results in failure of some goal-directed activity; • Spacecraft navigation system; ● Business-critical systems • Failure results in high economic losses; • Customer accounting system in a bank; ©Ian Sommerville 2004 Software Engineering, 7th edition. Chapter 3 Slide 4 System dependability ● For critical systems, it is usually the case that the most important system property is the dependability of the system. ● The dependability of a system reflects the user’s degree of trust in that system. It reflects the extent of the user’s confidence that it will operate as users expect and that it will not ‘fail’ in normal use. ● Usefulness and trustworthiness are not the same thing. A system does not have to be trusted to be useful. ©Ian Sommerville 2004 Software Engineering, 7th edition. Chapter 3 Slide 5 Importance of dependability ● Systems that are not dependable and are unreliable, unsafe or insecure may be rejected by their users. -

Interim Report Design, Cost, and Performance Analyses Executive Summary This report, jointly sponsored by the Defense Advanced Research Projects Agency (DARPA) and the National Aeronautics and Space Administration (NASA), is the result of a comprehensive study to explore the trade space of horizontal launch system concepts and identify potential near- and mid-term launch system concepts that are capable of delivering approximately 15,000 lbs to low Earth orbit. The Horizontal Launch Study (HLS) has produced a set of launch system concepts that meet this criterion and has identified potential subsonic flight test demonstrators. Based on the results of this study, DARPA has initiated a new program to explore horizontal launch concepts in more depth and to develop, build, and fly a flight test demonstrator that is on the path to reduce development risks for an operational horizontal take-off space launch system. The intent of this interim report is to extract salient results from the in-process HLS final report that will aid the potential proposers of the DARPA Airborne Launch Assist Space Access (ALASA) program. Near-term results are presented for a range of subsonic system concepts selected for their availability and relatively low development costs. This interim report provides an overview of the study background and assumptions, idealized concepts, point design concepts, and flight test demonstrator concepts. The final report, to be published later this year, will address more details of the study processes, a broader trade space matrix including concepts at higher speed regimes, operational analyses, benefits of targeted technology investments, expanded information on models, and detailed appendices and references. -

Computational methods such as resampling and bootstrapping are also used when data are insufficient for direct statistical methods. There is little point in making highly precise computer calculations on numbers that cannot be estimated accurately Group Interaction in High Risk Environments 1st edition. Categories : Underwater diving safety. Thus, the surface-supplied diver is much less likely to have an "out-of-air" emergency than a scuba diver as there are normally two alternative air sources available. Methods for dealing with Group Interaction in High Risk Environments 1st edition risks include Provision for adequate contingencies safety factors for budget and schedule contingencies are discussed in Chapter 6. This genetic substudy included Two Sister Study participants and their parents, and some Sister Study participants who developed incident breast cancer invasive or DCIS before age 50 during the follow-up period. In terms of generalizability, our sample is predominantly non-Hispanic white women, and the results may not apply to other racial or ethnic groups. This third parameter may give some management support by establishing early warning indicators for specific serious risks, which might not otherwise have been established. ROVs may be used together with divers, or without a diver in the water, in which case the risk to the diver associated with the dive is eliminated altogether. Suitable equipment can be selected, personnel can be trained in its use and support provided to manage the foreseeable contingencies. However, taken together, there is the possibility that many of the estimates of these factors would prove to be too optimistic, leading.
