Industrial Wireless Systems Workshop Proceedings

May 11, 2017
Author(s)
Richard Candell
Background: Wireless technology has great appeals to many manufacturers, in this case industrial automation systems, which include process control, discrete manufacturing, safety systems, and building automation. Applying wireless sensing and control

Dynamic Metrology and ASTM E57.02 Dynamic Measurement Standard

May 2, 2017
Author(s)
Roger V. Bostelman, Tsai H. Hong, Steven A. Legowik, Mili Shah
Optical tracking systems are used in a wide range of fields. The market for optical tracking systems has dramatically increased over the past several years to $1.2B revenue in 2014. This paper describes the new ASTM E3064 Standard test method procedures

Mobile Manipulator Stability Measurements

April 18, 2017
Author(s)
Roger V. Bostelman, Tsai H. Hong
Mobile manipulators are being marketed for material handling and other tasks. Manufacturers suggest the stability of the vehicle best when the onboard loading tapers the centroid to the center of the wheelbase as the payload height increases. Experiments

A Suite of Ontologies for Robotics and Automation

March 24, 2017
Author(s)
Sandro R. Fiorini, Julita Bermejo-Alonso, Paulo Goncalves, Edison Pignaton de Freitas, Alberto Olivares Alarcos, Joanna Isabelle Olszewska, Edson Prestes, Craig I. Schlenoff, Veera S. Ragavan, Signe Redfield, Bruce Spencer, Howard Li
One of the basic requirements for any type of robot communication (whether with other robots or humans) is the need for a common vocabulary along with clear and concise definitions. With the growing complexity of tasks that robots are expected to perform

What More Agile Robots Could Mean for Consumers

March 24, 2017
Author(s)
Craig I. Schlenoff
The ways that developers of robots have talked about their craft have been highly specialized to a given domain-and sometimes have varied even within the domain. This has made it difficult to share advances across the landscape of robot R&D and, in turn

Precision vs Accuracy Dilemma in Point-Based Rigid-Body Registration

March 23, 2017
Author(s)
Marek Franaszek, Geraldine S. Cheok
The purpose of a registration is to find the transformation between two coordinate frames: working frame (from which 3D data are transformed) and destination frame (to which the data are transformed). In point-based, rigid-body registration, the

Guideline for Automatic Guided Vehicle Calibration

March 2, 2017
Author(s)
Steven Legowik, Roger V. Bostelman, Tsai H. Hong, Elena R. Messina
This report documents the steps followed to calibrate an all-wheel steer Automatic Guided Vehicle (AGV) for optimal performance. Proper calibration of the steering and drive parameters of an AGV are critical for accurate dead-reckoning navigation, and

NIST HB 105-4, Specifications and Tolerances for Reference Standards and Field Standard Weights and Measures 4. Specifications and Tolerances for Liquefied Petroleum Gas and Anhydrous Ammonia Liquid Volumetric Provers (2016 Ed)

December 14, 2016
Author(s)
Georgia L. Harris, Val R. Miller
These specifications and tolerances are recommended as minimum requirements for standards used by state and local weights and measures officials and others in the regulatory verification of meters used in quantity determination of pressurized liquid

Lets Talk, Robots

November 21, 2016
Author(s)
Craig I. Schlenoff
This is a short article for Scientific Computing Magazine, at the request of the editor, that describes the IEEE 1872 IEEE Standard Ontologies for Robotics and Automation standard.

Sensor Calibration and Registration for Mobile Manipulators

November 16, 2016
Author(s)
Steven Legowik, Roger V. Bostelman, Tsai H. Hong
This paper describes the methods used to register a mobile manipulator to a workstation to perform assembly tasks. The nonlinear, least square model of the system is formulated and Ceres Solver[1] is used to compute the position of the robot arm relative
