ABSTRACT

In the past few years, robotic limbs have been attached to rotorcraft drones to perform aerial manipulation.  Unlike simple object pick-and-place, such mobile-manipulating drones are dexterous to perform tasks like valve-turning, hatch-opening, and tool-handling.  This is a paradigm shift where such drones actively interact with their environment rather than just passively surveil.  Aerial manipulation is challenging because such interaction yields reaction forces and torques that destabilize the drone.  This talk will provide an overview of aerial manipulation and showcase examples that could serve in infrastructure inspection, maintenance, and repair.

SPEAKER

Dr. Paul Oh is the Lincy Professor of Unmanned Aerial Systems in the Mechanical Engineering Department for the Howard R. Hughes College of Engineering.  He is establishing an unmanned autonomous systems laboratory at UNLV, complete with a fleet of drones and several humanoid robots. 

From 2000 to 2014, he served as a Mechanical Engineering Professor at Drexel University in Philadelphia and founded and directed the Drones and Autonomous Systems Laboratory (DASL). 

Oh is the former program director for robotics at the National Science Foundation where he managed a portfolio that suppored almost all academic non-military robotics research in American universities.  He has been a fellow of Boeing, and worked with the Office of Naval Research and NASA Caltech/Jet Propulsion Lab.

NON-CONTACT AIR-COUPLED SENSING FOR RAPID EVALUATION OF BRIDGE DECKS

Speaker: Dr. Jinying Zhu, University of Nebraska-Lincoln

ABSTRACT

Elastic wave-based non-destructive testing (NDT) methods are commonly used for evaluation of civil engineering infrastructure, including bridges, dams and buildings. However, most of these methods require coupling (direct contact) between sensors and the test surface, which significantly restricts the testing speed and consistency, especially for large scale concrete structures in civil engineering. The air-coupled sensing technology was developed by Dr. Jinying Zhu as a solution for rapid scanning of concrete infrastructure. In this webinar, Dr. Zhu will review the development of air-coupled sensing technique for civil engineering applications, including fundamental theory and field application of air-coupled sensing on concrete structures. She will also present a recently developed automated acoustic scanning system for quick bridge deck evaluation and imaging.
