    • An omni-directional vehicle (ODV) with a circular frame revolvably coupled to an appendage ring using a full circumferential coupling assembly. The appendage ring serves as a point of attachment for a push bar, trailer, tool, vehicle chassis, or other device. Two independent drive wheels located on an axis through the center of the frame are mounted at the same distance from a central vertical axis through the frame. Each wheel is powered independently and can rotate at variable speeds in either direction. The ODV is capable of movement in any direction by rotating the axis of the drive wheels to a position which is perpendicular to the desired direction of travel. The ODV can spin about its vertical axis such that the axis of the drive wheels can be oriented at any direction without changing the original footprint of the space that the frame occupies over the ground.
    • 具有圆形框架的全方位车辆(ODV),其可旋转地联接到使用全圆周联接组件的附肢环。 附肢环用作推杆,拖车,工具,车辆底盘或其他装置的附件点。 位于通过框架中心的轴上的两个独立的驱动轮以与中心垂直轴线相同的距离安装在框架上。 每个车轮独立供电,可以以任意方向以可变速度旋转。 通过将驱动轮的轴线旋转到垂直于所需行进方向的位置,ODV能够在任何方向上移动。 ODV可围绕其垂直轴旋转,使得驱动轮的轴线可以在任何方向上定向,而不改变框架占据地面的空间的原始占地面积。

    • A system and method of controlling a multi-wheel drive vehicle is provided. The invention is preferably applicable to the steering of such a vehicle and determines the individual velocities for each wheel drive. In this regard, the invention includes two general steps. The first step includes determining the distance of each wheel drive and a vehicle velocity reference point from a turning reference point. The second step includes ratioing each wheel drive's distance from the turning reference point with the vehicle velocity reference point's distance from the turning reference point. The ratios are then applied to a vehicle velocity associated with the vehicle velocity reference point to determine the velocity of each respective wheel drive. Once determined, the velocities are output to each wheel drive.
    • 提供了一种控制多轮驱动车辆的系统和方法。 本发明优选地适用于这种车辆的转向并确定每个车轮驱动的单独速度。 在这方面,本发明包括两个一般步骤。 第一步包括确定每个车轮驱动器的距离和车辆速度参考点与转动参考点的距离。 第二步包括将每个车轮驱动器与转向参考点的距离与车速参考点距离转弯参考点的距离进行比较。 然后将这些比率应用于与车辆速度参考点相关联的车辆速度,以确定每个相应车轮驱动器的速度。 一旦确定,速度被输出到每个车轮驱动。
