WebJul 3, 2024 · A nonlinear optimal control method for the ballbot autonomous vehicle Abstract: A nonlinear optimal (H-infinity) control approach is developed for the model of the ballbot. This robotic system consists of a rolling sphere with a rigid body, in the form of an inverted pendulum, mounted on top of the sphere. WebDue to their complicated dynamics and underactuated nature, spherical robots require advanced control methods to reveal all their manoeuvrability features. This paper considers the path tracking control problem of a spherical robot equipped with a 2-DOF pendulum. The pendulum has two input torques that allow it to take angles about the robot’s …
Webwheeled robots but will fail miserably in highly dynamic, balancing mobile robots like the ballbot. Such approaches result in sub-optimal, jerky motions and often drive the system unstable. In order to achieve robust, collision-free graceful motions, the motion planning and control for such systems must be integrated.
