Abstract
Mobile robots, in modern technology, demand a more robust localization in a complex environment. Currently, the most commonly used 2D LiDAR localization system for mobile robots requires maps that are constructed by 2D SLAM. Such systems do not cope well with dynamic environments and also have high deployment costs when moving robots to a new environment setting as they require the reconstruction of a map for each new place. In modern days, a floor plan is indispensable for an indoor environment. It typically represents essential structures such as walls, corners, pillars, etc. for humans to navigate in the environment. This information turns out to be crucial for robot localization. In this paper, we propose an approach for 2D LiDAR localization in an architectural floor plan. We use partial simultaneous localization and mapping (PSLAM) algorithm to generate a map while we concurrently aligned it to the floor plan using Monte Carlo Localization (MCL) method. Real-world experiments have been conducted with our proposed method which results in robust robot localization, the algorithm is even evaluated on a large discrepancies floor plan (discrepancies between the floor plan and real-world). Our algorithm demonstrates that its capabilities of localizing in real-time applications.
