TL;DR: In this article, the authors describe a vision system for a mobile robot which includes at least one radiation projector (14, 16) projecting a structured beam of radiation into the robot's environment.

TL;DR: In this article, a log polar mapper was used to match the image display to human perceptual resolution to achieve a 25:1 compression ratio with no loss of perceived cues, and then the perceptual channels were separated into low resolution, high discrimination level color and high resolution, low discrimination level contrast edges.

TL;DR: In this paper, an approach for the determination of a vehicle's orientation and position in an environment, such as a hallway, from an image of a retroreflective ceiling feature is presented.

TL;DR: In this paper, an approach for the determination of a vehicle's orientation and position in an environment, such as a hallway, from an image of ceiling lights is presented. But this approach requires a mobile robot that is pitched up obliquely at an intermediate angle between a horizon and a zenith.

TL;DR: In this paper, a mobile robotic materials transport system that performs fetch and carry tasks at Danbury Hospital is described, which can autonomously navigate along the main arteries of the hospital crossing between buildings via interconnecting hallways and uses radio to communicate with the elevator.
