The Canonical Robot Command Language (CRCL)

August 1, 2016
Author(s)
Frederick M. Proctor, Stephen B. Balakirsky, Zeid Kootbally, Thomas R. Kramer, Craig I. Schlenoff, William P. Shackleford
Industrial robots can perform motion with sub-millimeter repeatability when programmed using the teach-and-playback method. While effective, this method requires significant up-front time, tying up the robot and a person during the teaching phase. Off-line

Performance Evaluation of Human Detection Systems for Robot Safety

January 22, 2016
Author(s)
William P. Shackleford, Geraldine Cheok, Tsai H. Hong, Kamel Saidi, Michael O. Shneier
Detecting and tracking people is becoming more important in robotic applications because of the increasing demand for collaborative work in which people interact closely with and in the same workspace as robots. New safety standards allow people to work

Obstacle Detection and Avoidance from an Automated Guided Vehicle

September 18, 2014
Author(s)
Roger V. Bostelman, William P. Shackleford, Geraldine S. Cheok
Current automated guided vehicle (AGV) technology typically provides material handling flow along single or dual opposing-flow lanes in manufacturing and distribution facilities. An AGV stops for most any obstacle that may be in its path which then stops

New AGV Capabilities are Safety Driven
