Abstract: A mobile body includes a body, a front wheel and a rear wheel rotatably coupled to the front side and the rear side of the body respectively, a front wheel driving unit and a rear wheel driving unit coupled to the body and the front wheel and the rear wheel to transmit a driving force to the front wheel and the rear wheel respectively, a body angle acquisition unit to acquire a degree at which the body is tilted, and a processor. When a forward movement signal is input, the processor controls the front wheel driving unit so that when an inclination of the body to the ground is greater than a forward movement inclination threshold, the front wheel rotates at a speed based on a control value corresponding to an angular velocity of the body. As the angular velocity increases, the control value decreases.

Abstract: A machine and process for control of rotation of a vehicle about an axis of the vehicle is shown. A flight control system includes control laws that control the rotation of the vehicle around the axis of the vehicle. An estimate is derived for an inertia about the axis. The estimated inertia is derived from sensed quantities of material in a component of the vehicle. An inertia gain schedule and filter are added to enhance, using the estimated inertia, the accuracy of the control laws that control the rotation of the vehicle around the axis of the vehicle.

Abstract: A heading and attitude correction method and a heading and attitude correction system are provided. The method includes: obtaining attitude data in a period of time; performing a linear regression analysis on the attitude data and time points in the time period to obtain a regression line and a standard deviation; obtaining a deviation value between the attitude data and the regression line at each of the time points; excluding the attitude data for which the deviation value is greater than or equal to at least twice the standard deviation; grouping the attitude data according to a grouping value to form clusters; comparing a total quantity of the attitude data in each of the clusters, and defining one of the clusters with a largest total quantity as an ideal cluster; and calculating an average of the attitude data in the ideal cluster as a reasonable attitude data.

Abstract: A hierarchical modular arbitration architecture for a mobile platform guidance system is disclosed. In embodiments, the architecture comprises a hierarchy of arbitration layers, each arbitration layer narrower in scope than the layer above (e.g., mission objective arbitrators, route arbitrators, path arbitrators). Each arbitration layer includes one or more objective-based arbitrators in communication with one or more applications or modes. Each arbitrator receives control input (e.g., from the pilot, from aircraft sensors) and control signals from the level above, selecting a mode to make active based on decision agents within the arbitrator layer which control mode priorities and sequencing (e.g., some flight objectives may involve multiple arbitrators and their subject applications coordinating in sequence). Each arbitrator passes control signals associated with fulfilling the commands of the active mode to the level below and reports application and error information to the arbitrator level above and/or human/artificial pilot machine interfaces.

Abstract: The present invention discloses an unmanned aerial vehicle and a method for controlling a gimbal thereof. The method for controlling a gimbal includes: generating, by a flight control system, a yaw angular speed instruction of the unmanned aerial vehicle; and controlling, by a gimbal control system, a yaw axis motor of the gimbal according to the yaw angular speed instruction of the unmanned aerial vehicle. In the present invention, the yaw axis motor of the gimbal is jointly controlled by the flight control system and the gimbal control system, so that advantages of high-precision control and quick response of the gimbal control system are maximized. The advantages are used for compensating for deficiencies of the flight control system in yaw control, thereby improving the stability of a yaw channel of the gimbal, and completely resolving frame freezing of an aerial video when the unmanned aerial vehicle yaws at a low speed.
