Automatic map acquisition for navigation in domestic environment

چکیده
|An autonomous robot navigating in its environment needs a map representing the large-scale structure of the setting. There are a variety of di erent types of maps used in mobile robotics: for example, grid maps, maps containing geometrical beacons, or topological maps. Each of those poses its own constraints on the problem of acquiring the map, where its complexity is a major issue. We present a system that is able to build a topological map of large-scale indoor environments in a semi-autonomous way. This means that a person shows the robot around, interacts with it via a basic interface, the platform is following autonomously, and simultaneously creating the map. The acquisition mechanisms are rather simple and computationally inexpensive, due to the low complexity of the topological map. However, experiments show that this map is sufcient to navigate between arbitrary positions in the

An Approach for Automatic Matching of Descriptive Addresses
Address matching (also called geocoding) is an applied spatial analysis which is frequently used in everyday life. Almost all desktop and web-based GIS environments are equipped with a module to match the addresses expressed in pre-defined standard formats on the map. It is an essential prerequisite for many of the functionalities provided by location-based services (e.g. car navigation). Sever...

متن کاملPerson following through appearance models and stereo vision using a mobile robot
Following a person is an important task for mobile service and domestic robots in applications in which human-robot interaction is a primary requirement. In this paper we present an approach that integrates appearance models and stereo vision for efficient people tracking in domestic environments. Stereo vision helps in obtaining a very good segmentation of the scene to detect a person during t...
متن کاملNavigation of a Mobile Robot Using Virtual Potential Field and Artificial Neural Network
Mobile robot navigation is one of the basic problems in robotics. In this paper, a new approach is proposed for autonomous mobile robot navigation in an unknown environment. The proposed approach is based on learning virtual parallel paths that propel the mobile robot toward the track using a multi-layer, feed-forward neural network. For training, a human operator navigates the mobile robot in ...
متن کاملBuilding a Curious Robot for Mapping
Curiosity towards exploring new objects in one’s environment is a key driver of intelligent agents. We explore the problem of mapping in environments which are non-stationary, and where areas may exhibit different change patterns. This is an important challenge for potential “domestic” robots, which would have to perform tasks in houses. We propose a computational approach to building a curious...
