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)
BACKGROUND AND PURPOSE Moderate exercise training (60%-80% of maximal oxygen uptake) enhances the secondary antibody response. The mechanism underlying this enhancement, however, has not been determined. In moderate doses, endogenous opioids such as enkephalins enhance antibody response. Furthermore, serum concentrations of endogenous opioids increase in(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 mapper(More)
We present a navigation system which is able to steer an electronically controlled ground vehicle to given destinations considering all obstacles in its vicinity. The approach is designed for vehicles without a velocity controlled drive-train, making it especially useful for typical remote-controlled vehicles. The vehicle is controlled by sets of commands,(More)
