Curvature velocity method
WebCurvature in the path corresponds to turning and quite literally the amount by which your friend needs to turn the steering wheel away from the "straight" position: on a straight course, the steering wheel remains at zero-angle position and the curvature is zero, on a circular course the steering wheel is fixed at a constant angle in the left or … Webthe sensitivity of the method to this parameter value. 6 Results The curvature-velocity method (CVM) has been implemented and tested extensively on the Xavier mobile robot …

WebIn performing the transition from straight running to a curved path there must be a period of yaw acceleration in order to acquire the yaw velocity that matches the centripetal acceleration. The yaw acceleration is induced and controlled by yaw moments acting on the vehicle yaw inertia.
