A Review of Test Artifacts for Additive Manufacturing

May 24, 2012
Author(s)
Shawn P. Moylan, April L. Cooke, Kevin K. Jurrens, John A. Slotwinski, M A. Donmez
A standardized test part can be used to quantitatively evaluate the performance of a machine or process. This document reviews existing test artifacts used to characterize additive processes that are reported in the literature. Several aspects of the test

Using Competitions to Advance the Development of Standard Test Methods for Response Robots

May 17, 2012
Author(s)
Adam S. Jacoff, Raymond Sheh, Ann Virts, Tetsuya Kimura, Johannes Pellenz, Soren Schwertfeger, Jackrit Suthakorn
Competitions are an effective aid to the development and dissemination of standard test methods, especially in rapidly developing, highly varied fields such as Urban Search and Rescue robotics. By exposing the development process to highly developmental

Ground Truth for Evaluating 6 Degrees of Freedom Pose Estimation Systems

March 28, 2012
Author(s)
Jeremy Marvel, Joseph Falco, Tsai H. Hong
Systems developed to estimate poses of objects in 6 degrees of freedom (6DOF) Cartesian space (X, Y, and Z coordinates plus roll, pitch, and yaw) are reliant on the vendors' own processes to determine performance and measurement accuracy. These practices

2011 Solutions in Perception Challenge Performance Metrics and Results

March 22, 2012
Author(s)
Jeremy Marvel, Tsai H. Hong, Elena R. Messina
The 2011 Solutions in Perception Challenge (SPC) presented an international collection of teams with the opportunity to develop algorithms that could positively identify and accurately locate in space an arbitrary collection of artifacts. Researchers at

Emergency Response Robot Evaluation Exercise

March 22, 2012
Author(s)
Adam S. Jacoff, Hui-Min Huang, Ann Virts, Anthony Downs, Raymond Sheh
More than 60 robot test methods are being developed by a team lead by the National Institute of Standards and Technology (NIST) with the sponsorship of U.S. Department of Homeland Security (DHS). These test methods are being specified and standardized

Functional Requirements of a Model for Kitting Plans

March 22, 2012
Author(s)
Stephen B. Balakirsky, Zeid Kootbally, Thomas R. Kramer, Rajmohan Madhavan, Craig I. Schlenoff, Michael O. Shneier
Industrial assembly of manufactured products is often performed by first bringing parts together in a kit and then moving the kit to the assembly area where the parts are used to assemble products. Kitting, the process of building kits, has not yet been

Performance Evaluation of Robotic Knowledge Representation (PERK)

March 22, 2012
Author(s)
Craig I. Schlenoff, Sebti Foufou, Stephen B. Balakirsky
In this paper, we explore some ways in which symbolic knowledge representations have been evaluated in the past and provide some thoughts on what should be considered when applying and evaluating these types of knowledge representations for real-time

Evaluation of Proposed Test Artifacts for Five-Axis Machine Tools

November 18, 2011
Author(s)
Shawn P. Moylan, David Blumenfeld, Michael L. McGlauflin, Ronnie R. Fesperman Jr., M A. Donmez
Machining of a test artifact is an attractive method of evaluating the performance of a machine tool because the tests are often quick and do not require special instrumentation. An appropriate artifact should be complex enough to assess a machine's
