Abstract:Autonomous racing is a research field gaining large popularity, as it pushes autonomous driving algorithms to their limits and serves as a catalyst for general autonomous driving. For scaled autonomous racing platforms, the computational constraint and complexity often limit the use of Model Predictive Control (MPC). As a consequence, geometric controllers are the most frequently deployed controllers. They prove to be performant while yielding implementation and operational simplicity. Yet, they inherently lac… Show more
“…Our study utilizes a 1:10 scaled autonomous racing platform known as F1TENTH [16,17]. This platform facilitates safe, cost-effective, and rapid prototyping and has been instrumental in illustrating the principles and fundamentals of autonomous driving in various robotic tasks such as perception [5,18], planning [19] and control [20,21].…”
Range-measuring sensors play a critical role in autonomous driving systems. While Light Detection and Ranging (LiDAR) technology has been dominant, its vulnerability to adverse weather conditions is well-documented. This paper focuses on secondary adverse conditions -the implications of ill-reflective surfaces on range measurement sensors. We assess the influence of this condition on the three primary ranging modalities used in autonomous mobile robotics: LiDAR, Radio Detection and Ranging (RADAR), and Depth-Camera. Based on accurate experimental evaluation the paper's findings reveal that under ill-reflectivity, LiDAR ranging performance drops significantly to 33% of its nominal operating conditions, whereas RADAR and Depth-Cameras maintain up to 100% of their nominal distance ranging capabilities. Additionally, we demonstrate on a 1:10 scaled autonomous racecar how ill-reflectivity adversely impacts downstream robotics tasks, highlighting the necessity for robust range sensing in autonomous driving.
