Mobile Robot Self-Localization in Large-Scale Environments
نویسندگان
چکیده
This paper presents a new approach for the absolute self-localization of a mobile robot in structured large-scale environments. The requirements with regard to both, the necessary a-priori knowledge as well as the sensor equipment, are low. The algorithm scales up very well, due to a hybrid representation of the environment that augments a topological map with metric information. As a consequence, the method is especially suited for usage in large-scale service robotics applications. As an example for a future application, the so-called Navigation Assistant of the Bremen Autonomous Wheelchair “Rolland” is discussed. The self-localization results presented below stem from experiments with the wheelchair on a 2,176m long indoor and outdoor parcours on the campus of the Universität Bremen. Keywords— Navigation, Localization, Mobile Robots, Service Robots, Nonholonomic Robots

Map-merging in Multi-robot Simultaneous Localization and Mapping Process Using Two Heterogeneous Ground Robots
In this article, a fast and reliable map-merging algorithm is proposed to produce a global two dimensional map of an indoor environment in a multi-robot simultaneous localization and mapping (SLAM) process. In SLAM process, to find its way in this environment, a robot should be able to determine its position relative to a map formed from its observations. To solve this complex problem, simultan...
متن کاملNew Adaptive UKF Algorithm to Improve the Accuracy of SLAM
SLAM (Simultaneous Localization and Mapping) is a fundamental problem when an autonomous mobile robot explores an unknown environment by constructing/updating the environment map and localizing itself in this built map. The all-important problem of SLAM is revisited in this paper and a solution based on Adaptive Unscented Kalman Filter (AUKF) is presented. We will explain the detailed algorithm...
متن کاملA New Approach to Self-Localization for Mobile Robots Using Sensor Data Fusion
This paper proposes a new approach for calibration of dead reckoning process. Using the well-known UMBmark (University of Michigan Benchmark) is not sufficient for a desirable calibration of dead reckoning. Besides, existing calibration methods usually require explicit measurement of actual motion of the robot. Some recent methods use the smart encoder trailer or long range finder sensors such ...
متن کاملSelf-localization in Large-Scale Environments for the Bremen Autonomous Wheelchair
This paper presents RouteLoc, a new approach for the absolute self-localization of mobile robots in structured large-scale environments. As experimental platform, the Bremen Autonmous Wheelchair “Rolland” is used on a 2,176m long journey across the campus of the Universität Bremen. RouteLoc poses only very low requirements with regard to sensor input, resources (memory, computing time), and a-p...
متن کاملLarge-Scale Concurrent Mapping and Localization
The goal of concurrent mapping and localization (CML) is to enable a mobile robot to build a map of an unknown environment, while simultaneously using this map to navigate. This paper discusses some of the challenges that are encountered in the development of practical real-time implementations of CML for one or more autonomous mobile robots operating in large-scale environments.
