This paper presents basic characteristics of the problem of positioning errors propagation in collaborative multi robot environments. We propose two localization methods to achieve a cooperative positioning system using a collaborative autonomous robotic team for indoor surveillance applications. Based on case study simulation results, we were able to evaluate the error propagation process and to...
Localization systems for mobile robots are a trade-off between accuracy, robustness and costs. Current solutions for landmark based indoor localization are either expensive or inaccurate and unreliable. Accurate solutions for instance require costly infrastructure and/or high computational power. Additionally, self-balancing robots have particular challenges due to the unstable nature of the system...
Door detection is becoming an increasingly important subject in relation to autonomous mobile robot navigation in indoor environments. This paper presents an original approach that recognizes open and closed doors in 3D laser scanned data. The proposed technique uses both the geometric (i.e. XYZ coordinates) and colour (i.e. RGB/HSV) information provided by a calibrated set of 3D laser scanner and...
