  • Design Principles for Robust Grasping in Unstructured Environments
    Design Principles for Robust Grasping in Unstructured Environments A thesis presented by Aaron Michael Dollar to The Division of Engineering and Applied Sciences in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the subject of Engineering Sciences Harvard University Cambridge, Massachusetts October 25, 2006 © 2006 Aaron Michael Dollar All rights reserved. Robert D. Howe Aaron Michael Dollar Thesis Advisor Author Design Principles for Robust Grasping in Unstructured Environments Abstract Grasping in unstructured environments is one of the most challenging issues currently facing robotics. The inherent uncertainty about the properties of the target object and its surroundings makes the use of traditional robot hands, which typically involve complex mechanisms, sensing suites, and control, difficult and impractical. In this dissertation I investigate how the challenges associated with grasping under uncertainty can be addressed by careful mechanical design of robot hands. In particular, I examine the role of three characteristics of hand design as they affect performance: passive mechanical compliance, adaptability (or underactuation), and durability. I present design optimization studies in which the kinematic structure, compliance configuration, and joint coupling are varied in order to determine the effect on the allowable error in positioning that results in a successful grasp, while keeping contact forces low. I then describe the manufacture of a prototype hand created using a particularly durable process called polymer-based Shape Deposition Manufacturing (SDM). This process allows fragile sensing and actuation components to be embedded in tough polymers, as well as the creation of heterogeneous parts, eliminating the need for fasteners and seams that are iii often the cause of failure.

  • Radial Variation of the Interplanetary Magnetic Field Between 0.3 AU and 1.0 AU
    |00000575|| J. Geophys. 42, 591 - 598, 1977 Journal of Geophysics Radial Variation of the Interplanetary Magnetic Field between 0.3 AU and 1.0 AU Observations by the Helios-I Spacecraft G. Musmann, F.M. Neubauer and E. Lammers Institut for Geophysik and Meteorologie, Technische Universitiit Braunschweig, Mendelssohnstr. lA, D-3300 Braunschweig, Federal Republic of Germany Abstract. We have investigated the radial dependence of the radial and azimuthal components and the magnitude of the interplanetary magnetic field obtained by the Technical University of Braunschweig magnetometer experiment on-board of Helios-1 from December 10, 1974 to first perihelion on March 15, 1975. Absolute values of daily averages of each quantity have been employed. The regression analysis based on power laws leads to 2.55 y x r- 2 · 0 , 2.26 y x r- i.o and F = 5.53 y x r- i. 6 with standard deviations of 2.5 y, 2.0 y and 3.2 y for the radial and azimuthal components and magnitude, respectively. Here r is the radial distance from the sun in astronomical units. The results are compared with results obtained for Mariners 4, 5 and 10 and Pioneers 6 and 10. The differences are probably due to different epochs in the solar cycle and the different statistical techniques used. Key words: Interplanetary magnetic field - Helios-1 results. Introduction The study of the vanat10n of the components and magnitude of the in­ terplanetary magnetic field with heliocentric distance is very intersting at the present time. The mission of Mariner 10 to the inner solar system to a heliocentric distance of 0.46 AU and the missions of Pioneer 10 and Pioneer 11 to the outer solar system to heliocentric distances beyond 5 AU have provided new data over a wide range of heliocentric distance.

  • Space and Astrophysical Plasmas: Pervasive Problems
    PRAMANA ­c Indian Academy of Sciences Vol. 55, Nos 5 & 6 — journal of Nov. & Dec. 2000 physics pp. 645–654 Space and astrophysical plasmas: Pervasive problems CHANCHAL UBEROI Department of Mathematics, Indian Institute of Science, Bangalore 560 012, India Abstract. The observations and measurements given by Earth orbiting satellites, deep space probes, sub-orbital systems and orbiting astronomical observatories point out that there are impor- tant physical processes which are responsible for a wide variety of phenomena in solar-terrestrial, solar-system and astrophysical plasmas. In this review these topics are exemplified both from an observational and a theoretical point of view. Keywords. Heliosphere; solar corona; Alfven resonances; magnetic reconnection. PACS Nos 95.30 Q; 96.50 R 1. Introduction Space science is generally defined as investigations that are conducted by scientists using earth orbiting satellites, deep space probes like Pioneer series and sub-orbital systems. Space plasma sciences are now a very highly developed multidisciplinary area of research and can be divided into three areas: solar-terrestrial or Sun–Earth relations, solar-systems exploration and astrophysics. Though space science grew out of the rocket research which followed the end of World War II, the early investigations which began in 1946 concentrated on studies of the Earth’s atmosphere, solar radiation and cosmic rays from space. It was in 1958 that launch of Ex- plorer I and subsequent discovery of Van Allen belts which brought the scientific research in space sciences on to the list of other branches of physical and astrophysical sciences. These earlier flights of Pioneer I and subsequent series which laid the foundation of area of space plasma physics which as we now know has become a highly developed multidis- ciplinary area of research to understand the Sun–Earth or solar-terrestrial relations.

  • Apollo Over the Moon: a View from Orbit (Nasa Sp-362)
    chl APOLLO OVER THE MOON: A VIEW FROM ORBIT (NASA SP-362) Chapter 1 - Introduction Harold Masursky, Farouk El-Baz, Frederick J. Doyle, and Leon J. Kosofsky [For a high resolution picture- click here] Objectives [1] Photography of the lunar surface was considered an important goal of the Apollo program by the National Aeronautics and Space Administration. The important objectives of Apollo photography were (1) to gather data pertaining to the topography and specific landmarks along the approach paths to the early Apollo landing sites; (2) to obtain high-resolution photographs of the landing sites and surrounding areas to plan lunar surface exploration, and to provide a basis for extrapolating the concentrated observations at the landing sites to nearby areas; and (3) to obtain photographs suitable for regional studies of the lunar geologic environment and the processes that act upon it. Through study of the photographs and all other arrays of information gathered by the Apollo and earlier lunar programs, we may develop an understanding of the evolution of the lunar crust. In this introductory chapter we describe how the Apollo photographic systems were selected and used; how the photographic mission plans were formulated and conducted; how part of the great mass of data is being analyzed and published; and, finally, we describe some of the scientific results. Historically most lunar atlases have used photointerpretive techniques to discuss the possible origins of the Moon's crust and its surface features. The ideas presented in this volume also rely on photointerpretation. However, many ideas are substantiated or expanded by information obtained from the huge arrays of supporting data gathered by Earth-based and orbital sensors, from experiments deployed on the lunar surface, and from studies made of the returned samples.

    Geological Survey Research 1961 Synopsis of Geologic and Hydrologic Results GEOLOGICAL SURVEY PROFESSIONAL PAPER 424-A Geological Survey Research 1961 THOMAS B. NOLAN, Director GEOLOGICAL SURVEY PROFESSIONAL PAPER 424 A synopsis ofgeologic and hydrologic results, accompanied by short papers in the geologic and hydrologic sciences. Published separately as chapters A, B, C, and D UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON : 1961 FOEEWOED The Geological Survey is engaged in many different kinds of investigations in the fields of geology and hydrology. These investigations may be grouped into several broad, inter­ related categories as follows: (a) Economic geology, including engineering geology (b) Eegional geologic mapping, including detailed mapping and stratigraphic studies (c) Eesource and topical studies (d) Ground-water studies (e) Surface-water studies (f) Quality-of-water studies (g) Field and laboratory research on geologic and hydrologic processes and principles. The Geological Survey also carries on investigations in its fields of competence for other Fed­ eral agencies that do not have the required specialized staffs or scientific facilities. Nearly all the Geological Survey's activities yield new data and principles of value in the development or application of the geologic and hydrologic sciences. The purpose of this report, which consists of 4 chapters, is to present as promptly as possible findings that have come to the fore during the fiscal year 1961 the 12 months ending June 30, 1961. The present volume, chapter A, is a synopsis of the highlights of recent findings of scientific and economic interest. Some of these findings have been published or placed on open file during the year; some are presented in chapters B, C, and D ; still others have not been pub­ lished previously.
