The use of mobile robots in applications is steadily increasing, both in the industrial and the service domains. Most mobile robots achieve locomotion using wheels. As a consequence, they are subject to differential constraints that are nonholonomic, i.e., non-integrable. This article reviews the kinematic models of wheeled robots arising from these constraints and discusses their fundamental properties and limitations from a control viewpoint. An overview of the main approaches for trajectory planning and feedback motion control is provided.
