I recently began work at the CMU Robotics Institute and the nearby Intel Research Pittsburgh Lablet on extending the capabilities of sensor networks through the use of autonomous robotics. At CMU I work closely with Illah Nourbakhsh, among others. At Intel I work closely with Rahul Sukthankar, among others. My research interests include autonomous robotics, distributed systems, sensor networks, and visual navigation.

Recent Work
Basic Navigation via Optical Flow (November 2003)

As a warm-up exercise in advance of more substantial research, and as a demo for the Intel Lablet's November 2003 open house, Rahul Sukthankar, Illah Nourbakhsh, and I implemented visual odometry and obstacle avoidance capabilities on a camera-equipped Palm Pilot Robot Kit. We demonstrated: All of these were implemented via optical flow information derived from a single robot-mounted webcam. No encoders were available on the robot, and no other sensors were used. A poster and two videos demonstrating precipice detection and distance measurement are available.


Automatic Stitching of Multiple, Oblique Camera Views (November 2003)

Also as a demo for the Intel Lablet's November 2003 open house, Yan Ke, Rahul Sukthankar, and I implemented a demo of new keypoint-matching improvements developed by Yan and Rahul. In this demo we show four uncalibrated cameras viewing a common scene. Common keypoints are extracted from any camera overlap and used to define corresponding intercamera homographies, and then those homographies are used to stitch together a single mosaic containing all the camera views. The demo runs is near real-time, with an update latency of approximately 10-15 seconds.

The poster and photos of the demo will be available shortly.
