The Dynamic Structure of Everyday Life
(1988-10-01)
Computational theories of action have generally understood the organized nature of human activity through the construction and execution of plans. By consigning the phenomena of contingency and improvisation to ...
Real-Time Part Position Sensing
(1988-05-01)
A light stripe vision system is used to measure the location of polyhedral features of parts from a single frame of video camera output. Issues such as accuracy in locating the line segments of intersection in the image ...
Symbolic Construction of a 2D Scale-Space Image
(1988-04-01)
The shapes of naturally occurring objects characteristically involve spatial events occurring at many scales. This paper offers a symbolic approach to constructing a primitive shape description across scales for 2D ...
Preshaping Command Inputs to Reduce System Vibration
(1988-01-01)
A method is presented for generating shaped command inputs which significantly reduce or eliminate endpoint vibration. Desired system inputs are altered so that the system completes the requested move without residual ...
The Computational Study of Vision
(1988-04-01)
The computational approach to the study of vision inquires directly into the sort of information processing needed to extract important information from the changing visual image---information such as the three-dimensional ...
Dynamical Systems and Motion Vision
(1988-04-01)
In this paper we show how the theory of dynamical systems can be employed to solve problems in motion vision. In particular we develop algorithms for the recovery of dense depth maps and motion parameters using state ...
A Behavior-Based Arm Controller
(1988-06-01)
In this paper we describe a working, implemented controller for a real, physical mobile robot arm. The controller is composed of a collection of 15 independent behaviors which run, in real time, on a set of 8 loosely coupled ...
A Dexterity Measure for the Kinematic Control of Robot Manipulator with Redundany
(1988-02-01)
We have derived a new performance measure, product of minors of the Jacobian matrix, that tells how far kinematically redundant manipulators are from singularity. It was demonstrated that previously used performance ...
Scheme86: A System for Interpreting Scheme
(1988-04-01)
Scheme86 is a computer system designed to interpret programs written in the Scheme dialect of Lisp. A specialized architecture, coupled with new techniques for optimizing register management in the interpreter, allows ...
Model-Based Robot Learning
(1988-04-01)
Models play an important role in learning from practice. Models of a controlled system can be used as learning operators to refine commands on the basis of performance errors. The examples used to demonstrate this ...
