Explore the comprehensive theory and applications of wheeled mobile robots through this detailed lecture series from Northwestern University. Dive into the fundamental concepts of wheeled mobile robot systems, starting with basic principles and progressing to advanced topics including omnidirectional wheeled mobile robots with their unique kinematic properties and control mechanisms. Master the mathematical modeling of nonholonomic wheeled mobile robots, understanding the constraints that govern their motion and the implications for robot design and control. Examine the controllability aspects of wheeled mobile robots through extensive analysis covering reachability, controllability matrices, and the fundamental limitations imposed by nonholonomic constraints. Learn motion planning techniques specifically designed for nonholonomic mobile robots, including path planning algorithms that account for kinematic constraints and practical implementation considerations. Study feedback control strategies for nonholonomic mobile robots, covering stabilization techniques, trajectory tracking, and robust control methods that handle uncertainties and disturbances. Understand odometry principles and techniques for estimating robot position and orientation using wheel encoders and other sensors, including error analysis and calibration methods. Conclude with mobile manipulation concepts that integrate mobile platforms with robotic arms, exploring coordination strategies, workspace analysis, and the unique challenges of combining mobility with manipulation capabilities.
