Automated Vehicles and the Road Ahead Chris Mentzer, Assistant Director – R&D, Southwest Research Institute
The subject of automated driving has received international attention over the past several years as a new paradigm in transportation that may change how we live our lives. Companies ranging from existing automotive anufacturers to major technology companies to a variety of startups are all investing heavily into making automated vehicles a reality. Chris Mentzer will review a brief history of automated vehicle development and some of the terminology used in this space. He will also discuss the hardware and techniques currently involved in automated vehicle operation Ultimately the talk will focus on current challenges in this domain and hurdles the industry has yet to overcome for future adoption.
Chris Mentzer was extensively involved in SwRI’s Mobile Autonomous Robotics Technology Initiative (MARTI) program. This program created an autonomous vehicle out of a 2006 Ford Explorer with which SwRI was able to demonstrate key technologies improving upon the state-of-the-art in-ground vehicle autonomy. This system has been demonstrated alongside other industry leaders in the field at the Intelligent Transportation Systems (ITS) World Congress in 2008 and the Army’s Robotics Rodeo in 2009, 2010, and 2012. Chris performed system integration for the Small Unit Mobility Enhancement Technologies (SUMET) program for ONR and is currently the project manager for the Dismounted Soldier Autonomy Tools (DSAT), and follow-on Robotic Technology Kernel (RTK) programs for the US Army TARDEC. Chris is currently responsible for overseeing the unmanned ground vehicle programs at SwRI, including work in the commercial on-road, off-road and agricultural domains.
