Robots Podcast Interview

I was interviewed for the July 2nd, 2010 episode of the Robots Podcast, where I discussed robotics research at iRobot and the future of robotics.  You can listen to this interview on the Robots Podcast website or download the episode via iTunes.


The Dynamo Project

I was the Principal Investigator (PI) for the Dynamo Project, a project funded by the DARPA Defense Sciences Office to develop fast learning techniques for mobile robots driving at high speeds and over rough terrain.  Dynamo is part of the DARPA Maximum Mobility and Manipulation (M3) Program.  For Dynamo, we developed a new algorithm, Dynamic Threshold Learning (DTL), for rapid learning of robot control behaviors.

The Stingray Project

I was the PI for Stingray, a Phase II SBIR project funded by the US Army Tank-Automotive Research, Development, and Engineering Center (TARDEC).  The goal of this research project was to develop techniques for high-speed teleoperation of small unmanned ground vehicles (UGVs).  We worked with Chatten Associates to integrate their Head-Aimed Remote Viewer (HARV) with iRobot unmanned ground vehicle (UGV) platforms.  The HARV combines a head-tracking system with a head-mounted display and a remote gimbaled camera.  The camera tracks every motion of the operator's head, providing the illusion of being in the vehicle, and greatly increasing situational awareness.  We also developed semi-autonomous behaviors to help the operator control these UGVs at high speeds.

This video shows our initial experiments using the HARV to drive the prototype Warrior and a high-speed surrogate UGV (a modified, gas-powered R/C car used for testing) through a slalom course.

 


 

The Daredevil Project

I was the PI for the Daredevil Project, a Phase II SBIR project funded by TARDEC.  For Daredevil, we developed the perception techniques to allow robots to see through adverse weather (fog, rain, snow) and sparse foliage.  Robots often use LIDAR (laser ranging) or vision to detect obstacles, but these sensors have difficulty seeing through adverse weather and can be completely blocked by fog, smoke, or dust.  For Daredevil we used ultra wideband (UWB) radar in combination with LIDAR and vision to allow the Daredevil PackBot to avoid obstacles in all-weather conditions.

These images show how UWB radar can see through dense fog that blinds LIDAR and vision.  On the left, the Daredevil PackBot is in clear air, and both radar (green points) and LIDAR (red points) can see the obstacles in the room.  In these conditions, LIDAR provides more precise range data with better angular resolution.  On the right, the Daredevil PackBot is immersed in dense fog in the same room.  The LIDAR is unable to penetrate the fog beyond a depth of about one meter, but the UWB radar is completely unaffected.  If the robot were only equipped with LIDAR and vision, it would not be able to move safely in a fog-filled environment, but using UWB radar, the Daredevil PackBot is able to successfully avoid obstacles even in dense fog.

The Wayfarer Project

I was also the PI for the TARDEC-funded Wayfarer Project, a two-year, $1.3 million effort to develop autonomous urban navigation capabilities for man-portable mobile robots, such as the iRobot PackBot.  We equipped two Wayfarer PackBot prototypes with stereo vision and LIDAR to perform autonomous reconnaissance missions in urban terrain, including GPS-denied areas.  The new ruggedized Wayfarer navigation payload is shown at left, and a 3D map generated by the Instant Scene Modeler (iSM) during perimeter reconnaissance is shown at right.  (iSM was developed by Stephen Se at MDA Corporation and was integrated with Wayfarer at iRobot Corporation.)
