Localization for Mobile Robot Teams: A Distributed MLE Approach
نویسندگان
چکیده
This paper describes a method for localizing the members of a mobile robot team, using only the robots themselves as landmarks. We assume that robots are equipped with sensors that allow them to measure the relative pose and identity of nearby robots, as well as sensors that allow them to measure changes in their own pose. Using a combination of maximum likelihood estimation and distributed numerical optimization, we can, for each robot, estimate the relative range, bearing, and orientation of every other robot in the team. This paper describes the basic formalism, its distributed implementation, and presents experimental results obtained using a team of four mobile robots.

A 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 ...

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...
