Print on Demand. This book delves into the exciting field of mobile robotics and demonstrates a cutting-edge method for obstacle avoidance using real-time image processing and ow-based information. By mounting two cameras on a mobile robot with different elds of view (one narrow, one wide), the system can estimate time-to-contact and divergence of image ow. This information is then used by a behavioral controller to steer the robot down a "virtual corridor" while avoiding obstacles. The authors describe the integration of visual motion processing, retinal 2D representations, and behavior control, and the experiments conducted within o ce environments. The system represents a signi cant contribution to mobile robotics by combining ow-based information, foveal/peripheral processing, and behavior control into a novel system capable of robustly avoiding obstacles while wandering. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

The lure of using motion vision as a fundamental element in the perception of space drives this ejfort to use flow features as the sole cues for robot mobility. Real-time estimates of image flow and flow divergence provide the robot's sense of space. The robot steers down a conceptual corridor; comparing left and right peripheral flows. Large central flow divergence warns the robot of impending col lisions at dead ends. When this occurs, the robot turns around and resumes wandering. Behavior is generated by directly using flow-based information in the 2-d image sequence; no 3-d reconstruction is attempted. Active mechanical gaze stabilization simplifies the visual interpretation problems by reducing camera rota tion. By combining corridor following and dead-end deflection, the robot has wan dered around the lab at 30 cm/s for as long as 20 minutes without collision. The ability to support this behavior in real-time with current equipment promises expanded capabilities as computational power increases in the future.
