LEARNER Dataset: SLAM and Path Planning simulation environments for robots in challenging conditions This repository contains simulated environments for training and evaluating Deep Learning approaches, mainly targeting SLAM and Path Planning architectures for robots in dynamic and highly varying conditions.The dataset contains two different worlds: Warehouse, produced in Nvidia Omniverse Office, produced in Unreal Engine Both cases were developed with realistic lighting and atmospheric conditions and contain dynamic events, such as: Switching lights off Fire outbursts Heavy smoke Moving objects and humans We offer both the source files for the simulated worlds (USD_Files) and sequences of images recorded under different conditions (Frames) for each world. Acknowledgment This research is implemented in the framework of H.F.R.I call ``Basic research Financing (Horizontal support of all Sciences)'' under the National Recovery and Resilience Plan ``Greece 2.0'' funded by the European Union – NextGenerationEU (H.F.R.I. Project Number: 15339). We encourage the utilization of our dataset under the restriction of following the above acknowledgment.
