Multi-Robot Assembly Strategies and Metrics

January 26, 2018
Author(s)
Jeremy A. Marvel, Roger V. Bostelman, Joseph A. Falco
We present a survey of multi-robot assembly applications and methods, and describe trends and general insights into the multi-robot assembly problem for industrial applications. We focus on fixtureless assembly strategies featuring two or more robotic

Strategies for Improving Robot Registration Performance

January 26, 2018
Author(s)
Karl Van Wyk, Jeremy A. Marvel
The ability to calculate rigid-body transformations between arbitrary coordinate systems (i.e., registration) is an invaluable tool in robotics. This effort builds upon previous work by investigating strategies for improving the registration accuracy

Sensors for Safe, Collaborative Robots in Smart Manufacturing

November 30, 2017
Author(s)
Jeremy Marvel
The U.S. National Institute of Standards and Technology (NIST) is developing performance metrics for collaborative robotic systems for smart manufacturing applications. Using a suite of sensor platforms, feedback mechanisms, and novel test artifacts, NIST

Using Sensor Feedback to Accurately Estimate Part Pose in Gripper

September 28, 2017
Author(s)
Nithyananda Bhat Kumbla, Jeremy Marvel, Satyandra K. Gupta
High volume manufacturing use custom made fixtures during assembly operations. Small volume manufacturing cannot use fixtures in order to keep setup time and production cost low. The performance of the task in fixture-less assemblies depends on the

Modeling Performance Measurement of Mobile Manipulators

August 3, 2017
Author(s)
Roger V. Bostelman, Sebti Foufou, Tsai H. Hong
Mobile manipulators are being marketed around the world as single manufacturer systems (i.e., robot arm and vehicle manufactured by the same organization) and as independent robot arms, from a different manufacturer and integrated with automatic guided

Towards a Robot Task Ontology Standard

June 8, 2017
Author(s)
Stephen B. Balakirsky, Craig I. Schlenoff, Sandro R. Fiorini, Signe Redfield, Marcos Barreto, Hirenkumar Nakawala, Joel L. Carbonera, Larisa Soldatova, Julita Bermejo-Alonso, Fatima Maikore, Paulo J. Goncalves, Elena D. Momi, S. Veera Ragavan, Tamas Haidegger
Ontologies serve robotics in many ways, particularly in describing and driving autonomous functions. These functions are built around robot tasks. The goal of a recently established international study group is to develop a knowledge representation that

ACCURACY DEGRADATION ANALYSIS FOR INDUSTRIAL ROBOT SYSTEMS

June 7, 2017
Author(s)
Guixiu Qiao, Brian A. Weiss
As robot systems become increasingly prevalent in manufacturing environments, the need for improved accuracy continues to grow. Recent accuracy improvements have greatly enhanced automotive and aerospace manufacturing capabilities, including high-precision
