This paper describes a framework for precise self-localization using 2D radar scan matching based on a digitalized map. For this purpose, radars, odometers, a gyroscope and a global digital map are combined. Basically estimated ego-motion using motion sensors is improved using a novel scan matching approach in order to attain globally corrected self-localization results. The matching process is based on map information, iterative optimization using the Gauß-Helmert-Model and two novel weighting methods to register the environment map using radar information. This approach focuses on self-localization in a global frame without using Global Navigation Satellite Systems (GNSS). Beside our main innovation of using native non-discretized map lines for matching we also apply two novel weighting methods to cope with noisy radar scans for matching problem. By applying the Gauß-Helmert-Model we also consider the individual measurement uncertainties to make the approach even more robust against noisy data. Using map lines and data points categorizes our approach in the point-to-feature scan matching family. The performance and usability of the proposed approach is evaluated in real-world experiments and compared qualitatively and quantitatively to the state of the art matching methods. The results illustrate an improvement in precision and computational demand compared to other point cloud based matching methods.

In this study, we developed a four‐wheel‐driven autonomous mobile robot to transport heavy objects on narrow alleys and steep slopes. The robot, which weighs 450 kg, is driven by four 650 W hub motors to climb 20° steep slopes and travel through a narrow alley. Two 2D‐LiDARs attached to the front and rear of the robot body are used for highly accurate driving. A method based on the least squares approach for estimating the position and posture of the robot body is proposed by using the point cloud information of the side wall of the narrow alley. Field experiments on test courses demonstrated that the autonomous robot could transport heavy objects over steep slopes and travel in a narrow alley with high accuracy.
