    • A mobile robot navigating method for navigating an autonomous mobile robot utilizes a path planning unit, a posture control unit, a command signal converting unit, a current posture computing unit and a running mechanism, such as an autonomous carrier vehicle, capable of quickly and accurately controlling the mobile robot for steady running to a desired posture along a specified path. The mobile robot is controlled for running by a speed command including a desired speed for feed-forward control a speed correction for feed back control, and an angular velocity command including a desired angular velocity for feed-forward control and an angular velocity correction for feedback control. The mobile robot is controlled in a feed back and feed-forward control mode using the speed command and the angular velocity command so as to run steadily along an optimum path to a desired posture without meandering.

    • The novelty of this invention is that the vehicle's two degrees of freedom in motion is controlled by a single action of a driver. With this method, a driver can control a vehicle easily and intuitively. This invention might make it possible for impaired people to drive vehicles at their will for the first time. First, a sensor unit of a vehicle detects the Cartesian coordinates (x, y) that are specified by the driver. Second, a computing unit of the vehicle converts the coordinates (x, y) into a desired translation speed and a desired rotation speed, or into a desired translation speed and a desired curvature. Third, the motion control unit of the vehicle controls its motion using the desired translation speed and rotation speed, or the translation speed and curvature.
    • 本发明的新颖之处在于车辆的两个运动自由度由驾驶员的单一动作控制。 通过该方法,驾驶员可以容易且直观地控制车辆。 本发明可能使受损的人第一次以自己的意愿驾驶车辆成为可能。 首先,车辆的传感器单元检测由驾驶员指定的笛卡尔坐标(x,y)。 第二,车辆的计算单元将坐标(x,y)转换成期望的平移速度和期望的转速,或将其转换成期望的转换速度和期望的曲率。 第三,车辆的运动控制单元使用期望的平移速度和转速或平移速度和曲率来控制其运动。

    • A method of planning paths for autonomous carrier vehicles, such as a mobile robots, capable of planning curved paths consisting of cubic spirals smoother than those planned by conventional path planning methods. The path planned by the method of the invention is defined by one or two of cubic spirals with curvature expressed by a quadratic function of distance measured along the cubic spiral with zero curvatures at its opposite ends. The path is designed so that curvatures at the junctions are zero and the integral of the square of the derivative of curvature function between the opposite ends of the path is minimized. The mobile robot is able to travel very smoothly across the junctions when the integral of the square of the derivative of curvature is minimized.
    • 规划诸如移动机器人的自主运营商车辆的路径的方法,其能够规划由通过常规路径规划方法计划的平滑线的立方螺旋组成的弯道。 通过本发明的方法规划的路径由一个或两个具有曲率的立方体螺旋线定义,其曲率由在相对端处具有零曲率的三次曲线测量的距离的二次函数表示。 该路径被设计成使得接合处的曲率为零,并且在路径的相对端之间的曲率导数的平方的积分最小化。 当曲率导数的平方的积分最小化时,移动机器人能够非常顺利地穿过交叉点行进。
