The advance of sensing system is bringing significant revolution to the field of robotics. The course will try to give the students an up-to-date overview of the mobile robots and the related sensory systems, their respective working principles, and higher-level applications. This class will expose the students to the cutting-edge development of today's autonomous mobile robots, such as autonomous driving. We will cover state sensors such as GPS, IMU and GNSS, vision sensors such as optical principles in cameras, RGB cameras and different types of advanced cameras, and advanced sensors such as LiDARs, millimeter-waves radars, advanced ultrasonic sensors. We will also cover mathematical models and algorithms such as probabilistic approach of sensor signal, Kalman filter and other robotic algorithms, computer vision and deep learning, and localization, mapping and SLAM (Simultaneous Localization And Mapping).
