Beta Robots: Robot Ethics (Part 2)

This episode closes a two-part special looking at ethical issues in robotics. Given the broad and controversial nature of this topic, we speak with two world-renowned experts in ethics with often-opposing views. Our first guest featured on our last episode, Noel Sharkey, is Professor of Public Engagement, Artificial Intelligence and Robotics at the University of Sheffield in the UK. In today's episode we interview Ronald Arkin, the director of the Mobile Robot Lab and Associate Dean of Research at Georgia Tech in the US. Both researchers discuss issues such as military robots, robots in the society, medical robots and legal responsibilities. Their opinions on these subjects have been widely covered by the media, international organizations and academia. The interviews were recorded individually and both researchers were asked the same questions.



Ronald Arkin




Ronald Arkin is Regents' Professor and Director of the Mobile Robot Laboratory at the Georgia Institute of Technology where he also serves as the Associate Dean for Research in the College of Computing.



By looking at a wide variety of autonomous mobile robots in his lab, either aerial, ground-based or swarming, he's become a world renowned expert in robotics and control, authoring corner-stone textbooks such as Behavior-Based Robotics (MIT Press 1998).



In the past years, Arkin has become one of the pioneers in robot ethics, tuning in at the start of discussions on Roboethics in 2004. Since then he's written several publications on the ethics of military robots, arguing that robots in the future could be more ethical than humans on the battlefield. Embedded with a sense of ethics, or even guilt, such robots could perhaps be able to make decisions in life-death situations. His views are presented in his new book to appear in spring 2009 entitled Governing Lethal Behavior in Autonomous Robots.



Other than military robots, Arkin discusses issues such as the attachment of people to robots, and more generally, the role of robots as care-givers or workers in the society. He also touches on the subject of medical robots, or prosthetic, capable of enhancing the human being.



Finally, with so many questions raised on the ethics of robotics, we look into the entities which will be setting limits on the use of tomorrows robots as well as defining who takes the responsibly of their actions. Could the robots themselves be held responsible in the end?

The 2007 Darpa Urban Challenge


Our inaugural episode centers on the 2007 DARPA Urban Challenge, featuring interviews with professor Daniel Huttenlocher from Team Cornell and Rick Yoder from Velodyne, a producer of LIDAR sensors used by several teams in the challenge.



Dan Huttenlocher



Robots: Episode1
Dan Huttenlocher is professor of Computing, Information Science and Business at Cornell University in Ithaca New York. As the co-leader of Cornell’s racing team for the 2007 DARPA Urban Challenge, he spent countless hours testing the autonomous car which finally finished among the six final automobiles capable of following California's road code over 56 miles of a mock urban environment. With design in mind, his team of 13 students managed to discretely embed a slick black 2007 Chevy Tahoe with a Velodyne LIDAR, three IBEO 1.5D LIDARs, five 1D SICK LIDARs, five millimeter-wave radars, and four cameras. Of course, millions of data points per second don't come for free and Cornell's trunk is the home of 17 dual core processors.




Since a pile of impressive hardware and CPU is not enough, Team Cornell developed the software needed to allow their robot to locally represent its location on the road and further figure out, on a more global scale, where it really was in the world. However, knowing where you are isn't nearly enough, you also need to be able to figure our where other objects are and ideally track them and reason about their next moves. So, what went wrong in this little fender bender with MIT's car (see video below)? I guess the professional human drivers during the challenge weren't wrong, when they said that Cornell's car drove like a human.











Velodyne LIDAR



Robots: Episode1
Rick Yoder is an employee at Velodyne, a new-comer in the field of LIDAR (Light Detection and Ranging) sensors. The HDL-64E LIDAR uses an impressive 64 stationary lasers on a base rotating at 900rpm. This sensor was specifically designed for the 2007 DARPA Urban Challenge, and was used by around a third of the participating teams, although some other teams may have been turned away by the hefty $75,000USD price tag! Though not yet destined for the consumer market, Rick hints at a new series of sensors that may soon find their way into your car.
