The Daredevil Project
I'm the Principal Investigator for Daredevil, a Phase II SBIR project
funded by the US Army Tank-Automotive Research, Development,
and Engineering Center (TARDEC). The goal of the
project is to use ultra wideband (UWB) radar sensors to allow small UGVs
(like the iRobot PackBot) to navigate through foliage (tall grass,
forests, jungles) and adverse weather (rain, snow, dust) while avoiding
obstacles.
Most autonomous robots
use sensors such as vision or laser rangefinders (LIDAR) to detect
obstacles. While these sensors work well to detect solid obstacles
in open space, they typically are not able to differentiate a solid
object (which the robot needs to steer around) from foliage such as
tall grass (which the robot can push through). One of the primary
goals of this project is to use UWB radars to see through foliage and
to be able to differentiate between solid objects (such as people,
rocks, or vehicles) and vegetation.
Our initial results have been very promising. The first image
below shows a person (Mike) in a field of tall grass, barely visible to
human eyesight. The second image shows the UWB radar data, which
clearly detects Mike through the vegetation.
The Sagittarius Project
I'm also the Prinicpal Investigator for the Sagittarius Project, a
Phase I SBIR funded by the Air
Force Research Laboratory at Wright-Patterson Air Force Base.
The goal of Sagittarius is to develop techniques that will enable
unmanned ground vehicles (UGVs) and unmanned air vehicles (UAVs) to
cooperate for tracking elusive dismounts (people who are trying to hide)
in urban terrain. This is a joint project with Sanjiv Singh and Christopher Geyer at
the Carnegie Mellon Robotics Institute.
The Wayfarer Project
I was the Principal Investigator for the 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.
Wayfarer is funded by the U.S. Army Tank-automotive and Armaments
Command (TACOM) Tank-Automotive
Research, Development, and Engineering Center (TARDEC). We have
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 above left, and a 3D map generated by the Instant Scene
Modeler (iSM) during perimeter reconnaissance is shown above
right. (iSM was developed by Stephen Se at MDA Corporation
and was integrated with Wayfarer at iRobot
Corporation.)

While at the Naval
Research Laboratory, I developed frontier-based
exploration, a technique that allows mobile robots to explore and
map unknown environments.
