We describe a framework for detecting and tracking continuous ldquotrailsrdquo in images and image sequences for autonomous robot navigation. Continuous trails are extended regions along the ground such as roads, hiking paths, rivers, and pipelines which can be navigationally useful for ground-based or aerial robots. Our approach to single-image trail segmentation incorporates both bottom-up and top-down...
This paper discusses a sketch interface that can be used to guide a mobile robot along a specified path in its unfamiliar place. With the sketch interface, the user draws a rough map to give navigation tasks to robots. Because sketched maps often suffer from various inaccuracies and large errors in landmarks, we discuss what kinds of uncertainties in the rough maps would mainly have effects on navigating...
This paper reports an autonomous cooperative navigation system for robot formations in realistic scenarios. The formation movement control is based on a virtual structure composed by spring-dampers elements, which allows the formation to comply with the environment shape. A different navigation strategy is applied to the leader of the formation and to the rest of robots of the team. The leader plans...
In this research, the mapping and navigation system in a wide space in a building for mobile robots which have laser range finders and stereo cameras was achieved. The map was described as a combination of topological corridor maps and metric room maps. The topological corridor maps have nodes which represent entrances of each room, and the grid-based room maps have accurate information about positions...
This paper examines the roots of purposive behavior in an agent surrounded by a stationary unknown environment. The investigation focuses on deriving a structure for a behavior generation mechanism (BGM) that would semantically embed an agent in the context of its environment. The BGM is made to adhere to the situated, embodied, intelligent, and emergent requirements that were suggested by Brooks...
