Robotics & Informatics for Geotechnical Systems

Brief Description

Recent advances in robotics and informatics pave new directions for our society and are destined to impact the entire breadth of geotechnical engineering practice and research, including the way we characterize, design, monitor and perceive risk of geotechnical systems. Robotic platforms provide an opportunity for spatially-distributed, mobile, data-driven sensing that allow for optimized monitoring on locations that are most critical to focus on and with the appropriate types of measurements. Land-based, floating, underwater, or aerial robotic platforms have not only unprecedented sensing capabilities, but also outstanding, untapped, computational capabilities that can promote data fusion and lead to better characterization of the interaction of geosystems with the environment. Robotic platforms are bringing quickly big data to geotechnical engineering. My research work has been focusing on the use of these unprecedented capabilities to promote resiliency and sustainability of geotechnical infrastructure systems.

Use of Drones to Map Landslides following the Gorkha 2015 earthquake in Nepal

More than 20,000 landslides took place in Nepal during the Mw 7.8 Gorkha earthquake on April 25th 2015 . This video describes the landslide mapping efforts of researchers from the University of Michigan (Dr. Marin Clark, and Dr. Dimitrios Zekkos), University of Southern California (Dr. Josh West) in the US and Tribhuhan University (Dr. Deepak Chamlagain) in Nepal. The research team used drones and photogrammetry principles to view map and create 3D models of large rock slides, debris flows and even rockfalls. The drone was particularly needed in this case, because of the steep topography and the large size and runout length of some of the landslides, that made it nearly impossible to map otherwise. Video prepared by Geoengineer.org staff.

Unprocessed Drone-based Video Footage Following the 2015 Lefkada Earthquake

Raw Data video of reconnaissance following the Mw 6.4 earthquake that occurred near Lefkada island in Greece, on November 17th 2015. Our team deployed within less than 48 hrs following the earthquake and collected drone-based video footage of affected areas. The UAAV successfully by-passed roads that were closed by landslides and other damaged infrastructure that impacted accessibility. Footage was released immediately following UAAV deployment to make available data and footage that may prove valuable to first responders, engineers, rescue operators and damage assessors.
