— The European Land Robotic Trial (ELROB), which was held for the fifth time in 2010, is designed to compare unmanned ground vehicles in realistic outdoor tasks. It addresses the need to create a benchmark that can reproducibly compare and evaluate different robot systems. While robot trials like the DARPA Grand Challenge or the RoboCup have proven to be(More)
In this paper we discuss the problem of monitoring and searching an indoor environment for an intruder with a group of mobile robots. We present a graph-based algorithm to coordinate a group of robots which takes the limitations and uncertainties of sensors into account and is able to find good coordination plans efficiently even for large environments. We(More)
We present a fast method of detecting loop closure opportunities through the use of similarity measures on histograms extracted from 3-D LIDAR data. We avoid computationally expensive features and compute histograms over simple global statistics of the LIDAR scans. The resulting histograms encode sufficient information to detect spatially close scans with(More)
—This paper presents technical details of the robot framework that is used by the FKIE team for the participation in the three scenarios Mule, Approach, and Camp Security of the ELROB 2011. Our navigation software used for both, the Mule and the Approach scenario, is based on a local navigation using motion patterns. Additionally, we employ a FastSLAM(More)
