Leandro Buss Becker, Anthony Downs, Craig I. Schlenoff, Justin Albrecht, Zeid Kootbally, Angelo Ferrando, Rafael Cordoso, Michael Fisher
The "Agile Robotics for Industrial Automation Competition" (ARIAC) is an international robotic competition carried out in a simulated ROS2/Gazebo factory floor. Competitors control a robot, overcoming a range of agility challenges in this simulated

Laser Power Accuracy of Additive Manufacturing Systems - A Round Robin Study

September 11, 2023
Author(s)
Brian Simonds, Kyle Rogers, Paul A. Williams
High power lasers are at the core of metal additive manufacturing (AM) systems and the accurate delivery of laser energy is critical to part performance. We have performed a round robin style survey of U.S. AM equipment across industry, academia, and
