Author(s)
Michael E. Newman, Stephen B. Balakirsky
This article describes the 2011 Robot Challenge that took place at the International Conference on Robotics and Automation in Shanghai, China. The quartet of contests-the Virtual Manufacturing Automation Competition (VMAC), the Mobile Microrobotics

Large-Area Overhead Manipulator for Access of Fields

July 22, 2011
Author(s)
Jeffrey W. White, Roger V. Bostelman
Multi-axis, cable-driven manipulators have evolved over many years providing large area suspended platform access, programmability, relatively rigid and flexibly- positioned platform control and full six degree of freedom (DOF) manipulation of sensors and

Four-color laser white illuminant demonstrating high color-rendering quality

July 4, 2011
Author(s)
Alexander Neumann, Jonathan Wierer , Wendy L. Davis, Yoshi Ohno, Steve Brueck, Jeff Tsao
Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors. Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers

June 30, 2011
Author(s)
Ronald A. Ginley
The millimeter and submillimeter frequency ranges are becoming very important to today’s electronics, security and communication industries. NIST has undertaken a research program to aggressively pursue this area. This paper will cover the millimeter

Advanced Sensing Towards Improved Forklift Safety

February 4, 2011
Author(s)
Roger V. Bostelman, William P. Shackleford
The National Institute of Standards and Technology's Intelligent Systems Division has been researching advanced three-dimensional (3D) imaging sensors and their use in manufacturing towards improving forklift safety. Experiments are presented in this paper

Co-X Panel Discussion

February 4, 2011
Author(s)
Elena R. Messina, Brian A. Weiss, Rajmohan Madhavan
Robots as co-protectors, co-inhabitants, co-workers, co-integrants, or more generically, "Co-X" will improve effectiveness, efficiency, safety, security, and improve quality of life in the coming years. In-keeping with the theme of PerMIS'10, which

Comprehensive Standard Test Suites for the Performance Evaluation of Mobile Robots

January 31, 2011
Author(s)
Adam S. Jacoff, Hui-Min Huang, Elena R. Messina, Ann M. Virts, Anthony J. Downs
Robots must possess certain sets of capabilities to suit critical operations such as emergency responses. In the mobility function, ground robots must be able to handle many types of obstacles and terrain complexities, including traversing and negotiating

Evaluation of Maps using Fixed Shapes: The Fiducial Map Metric

January 31, 2011
Author(s)
Soren Schwertfeger, Adam S. Jacoff, Christopher Scrapper, Johannes Pellenz, Alexander Kleiner
Mapping is an important task for mobile robots. Assessing the quality of those maps is an open topic. A new approach on map evaluation is presented here. It makes use of artificial objects placed in the environment named "Fiducials". Using the known ground

Metrics for Mixed Pallet Stacking

January 31, 2011
Author(s)
Stephen B. Balakirsky, Thomas R. Kramer, Frederick M. Proctor
Stacking boxes of various sizes and contents on pallets (i.e. making mixed pallets) is a primary method of preparing goods for shipment from a warehouse to a store or other distant site. Many billions of dollars are spent each year in preparing, shipping
