Algorithmic foundations of robotics X proceedings of the Tenth Workshop on the Algorithmic Foundations of Robotics by Emilio Frazzoli( )

2 editions published in 2013 in English and held by 27 WorldCat member libraries worldwide

Algorithms are a fundamental component of robotic systems. Robot algorithms process inputs from sensors that provide noisy and partial data, build geometric and physical models of the world, plan high-and low-level actions at different time horizons, and execute these actions on actuators with limited precision. The design and analysis of robot algorithms raise a unique combination of questions from many elds, including control theory, computational geometry and topology, geometrical and physical modeling, reasoning under uncertainty, probabilistic algorithms, game theory, and theoretical computer science. The Workshop on Algorithmic Foundations of Robotics (WAFR) is a single-track meeting of leading researchers in the eld of robot algorithms. Since its inception in 1994, WAFR has been held every other year, and has provided one of the premiere venues for the publication of some of the eld's most important and lasting contributions. This books contains the proceedings of the tenth WAFR, held on June 13{15 2012 at the Massachusetts Institute of Technology. The 37 papers included in this book cover a broad range of topics, from fundamental theoretical issues in robot motion planning, control, and perception, to novel applications

The design of a mechanical assembly system by Tomás Lozano-Pérez( Book )

6 editions published between 1976 and 1977 in English and Undetermined and held by 11 WorldCat member libraries worldwide

This thesis describes a mechanical assembly system called LAMA. The goal of the work was to create a mechanical assembly system that transforms a high-level description of an automatic assembly operation into a program for execution by a computer-controlled manipulator. This system allows the initial description of the assembly to be in terms of the desired effects on the parts being assembled. (Author)
On the complexity of partitioning an assembly by R. H Wilson( Book )

2 editions published in 1992 in English and held by 9 WorldCat member libraries worldwide

Abstract: "We consider the following problem that arises in assembly planning: given an assembly, identify a subassembly that can be removed as a rigid object without disturbing the rest of the assembly. This is called the assembly partitioning problem. Polynomial-time solutions have been presented when the motions allowed for the separation are of certain restricted types. We show that for assemblies of polyhedra, the partitioning problem for arbitrary sequences of translations is NP- complete. The reduction is from 3-SAT
Parsing intensity profiles by Tomás Lozano-Pérez( Book )

4 editions published in 1975 in English and Undetermined and held by 8 WorldCat member libraries worldwide

Much low-level vision work in (artificial intelligence) deals with one-dimensional intensity profiles. This paper describes PROPAR, a system that allows a convenient and uniform mechanism for recognizing such profiles. PROPAR is a modified Augmented Transition Networks parser. The grammar used by the parser serves to describe and label the set of acceptable profiles. The input to the parser are descriptions of segments of a piecewise linear approximation to an intensity profile. A sample grammar is presented and the results discussed. (Author)
Robot programming by Tomás Lozano-Pérez( Book )

6 editions published between 1982 and 1983 in English and Undetermined and held by 7 WorldCat member libraries worldwide

The industrial robot's principal advantage over traditional automation is programmability. Robots can perform arbitrary sequences of pre-stored motions or of motions computed as functions of sensory input. This paper reviews requirements for and developments in robot programming systems. The key requirements for robot programming systems examined in the paper are in the areas of sensing, world modeling, motion specification, flow of control, and programming support. Existing and proposed robot programming systems fall into three broad categories: guiding systems in which the user leads a robot through the motions to be performed, robot-level programming systems in which the user writes a computer program specifying motion and sensing, and task-level programming systems in which the user writes a computer program specifying motion and sensing, and task-level programming systems in which the user specifies operations by their desired effect on objects. A representative sample of systems in each of these categories is surveyed in the paper. (Author)

A subdivision algorithm in configuration space for findpath with rotation by Rodney Allen Brooks( Book )

4 editions published in 1982 in English and held by 6 WorldCat member libraries worldwide

In this paper the authors present an algorithm for finding collision-free paths for a rigid polygonal object moving through space that is cluttered with obstacle polygons. The paths can include rotations of the object. The algorithm will find a path from a given initial position and orientation to a goal position and orientation if such a path exists, subject only to a user-specified resolution limit on displacements. The problem addressed here is an instance of the problem known as the findpath or mover's problem in robotics. The problem arises when planning the motion of a robot manipulator or mobile robot in an environment with known obstacles

Automatic planning of manipulator transfer movements by Tomás Lozano-Pérez( Book )

2 editions published in 1980 in English and held by 5 WorldCat member libraries worldwide

This paper deals with the class of problems that involve finding where to place or how to move a solid object in the presence of obstacles. The solution to this class of problems is essential to the automatic planning of manipulator transfer movements, i.e. the motions to grasp a part and place it at some destination. This paper presents algorithms for planning manipulator paths that avoid collisions with objects in the workspace and for choosing safe grasp points on objects. These algorithms allow planning transfer movements for cartesian manipulators. The approach is based on a method of computing an explicit representation of the manipulator configurations that would bring about a collision. (Author)
Recognition and localization of overlapping parts from sparse data by William Eric Leifur Grimson( Book )

1 edition published in 1985 in English and held by 4 WorldCat member libraries worldwide

Abstract: "This paper discusses how sparse local measurements of positions and surface normals may be used to identify and locate overlapping objects. The objects are modeled as polyhedra (or polygons) having up to six degrees of positional freedom relative to the sensors. The approach operates by examining all hypotheses about pairings between sensed data object surfaces and efficiently discarding inconsistent ones by using local constraints on: distances between faces, angles between face normals, and angles (relative to the surface normals) of vectors between sensed points

Philosophy and AI : essays at the interface by Robert Cummins( Book )

1 edition published in 1991 in English and held by 4 WorldCat member libraries worldwide

Philosophers have found that the concepts and technology of artificial intelligence provide useful ways to test theories of knowledge and reason. Conversely, researchers in artificial intelligence, noting that the production of information-processing systems requires a prior theory of rationality, have begun writing philosophy. Philosophy and AI presents invited contributions that focus on the different perspectives and techniques that philosophy and AI bring to the theory of rationality
An approach to automatic robot programming by Tomás Lozano-Pérez( Book )

3 editions published in 1985 in English and Undetermined and held by 4 WorldCat member libraries worldwide

Abstract: "In this paper we propose an architecture for a new task-level system, which we call TWAIN. Task-level programming attempts to simplify the robot programming process by requiring that the user specify only goals for the physical relationships among objects, rather than the motions needed to achieve those goals. A task-level specification is meant to be completely robot independent; no positions or paths that depend on the robot geometry or kinematics are specified by the user. We have two goals for this paper. The first is to present a more unified treatment of some individual pieces of research in task planning, whose relationship has not previously been described

Model-based recognition and localization from sparse range or tactile data by William Eric Leifur Grimson( Book )

3 editions published between 1983 and 1984 in English and held by 3 WorldCat member libraries worldwide

This paper discusses how local measurements of three-dimensional positions and surface normals (recorded by a set of tactile sensors, or by three-dimensional range sensors), may be used to identify and locate objects, from among set of known objects. The objects are modeled as polyhedra having up to six degress of freedom relative to the sensors. We show that inconsistent hypotheses about pairings between sensed points and objects surfaces can be discarded efficiently by using local constraints on: distances between faces, angles between face normals, and angles (relative to the surface normals) of vectors between sensed points. We show by simulation and by mathematical bounds that the number of hypotheses consistent with these constraints is small. We also show how to recover the position and orientation of the object from the sense data. The algorithm's performance on data obtained from a triangulation range sensor is illustrated. (Author)
