Vision-Based Mobile Robot Navigation
Department of Mathematics and Computer Science
Getting a robot to make its way around in an unknown environment is a
hard problem. Computer vision -- interpretating images taken with a
camera -- is an even harder problem. We've been working with several
students at Middlebury on both of these fronts to help our mobile
robots navigate with the aid of simple visual landmarks.
In this joint talk, we will describe the visual landmark patterns we
designed for instant detection with the robot's camera, and how the
robot uses this information to find its way among the tables and
chairs in our lab. The talk will include a short video, as well as an
actual demonstration of some of the robot's tricks.
Amy Briggs received her PhD in Computer Science from Cornell
University in 1995. Since then she has been an Assistant Professor of
Mathematics and Computer Science at Middlebury College. Her research
interests are in algorithms for robot navigation and sensor planning,
and computational geometry.
Daniel Scharstein studied Computer Science at the Universitaet
Karlsruhe, Germany, and received his PhD from Cornell University in
1997. He is now an Assistant Professor of Mathematics and Computer
Science at Middlebury College. His research interests include computer
vision, in particular stereo vision and image-based rendering, as well
