    • The present invention relates to a method (300) and a system (100) for guiding a robotic garden tool to a predetermined position. The robotic garden tool includes a control unit (104) and a sensor unit (102) to detect signals. The sensor unit (102) detects a first signal (110) from a first signal source (106) and the robotic garden tool follows the first signal (110) at a varying distance from the first signal source (106) that is less than or equal to a maximum distance to the first signal source, towards the predetermined position. Wherein, the varying distance is a function of the strength of the detected first signal (110). While detecting the first signal (110), the sensor unit may also detect a second signal (112) from a second signal source (108). The robotic garden tool follows the first signal (110) at a varying distance that is less than or equal to the maximum distance to the first signal source, wherein the maximum distance, at least in part, is now set based on the strength of the detected second signal (112), to reach a predetermined position.
    • 本发明涉及一种用于将机器人园艺工具引导到预定位置的方法(300)和系统(100)。 机器人园艺工具包括一个控制单元(104)和一个用于检测信号的传感器单元(102)。 所述传感器单元(102)从第一信号源(106)检测第一信号(110),并且所述机器人花园工具以与所述第一信号源(106)不同的距离与所述第一信号源(106)不同的距离跟随所述第一信号(110) 等于到第一信号源的最大距离朝向预定位置。 其中,变化的距离是检测到的第一信号(110)的强度的函数。 在检测到第一信号(110)的同时,传感器单元还可以从第二信号源(108)检测第二信号(112)。 机器人花园工具以小于或等于与第一信号源的最大距离的变化距离跟随第一信号(110),其中至少部分地基于最大距离来设置最大距离 检测到的第二信号(112)到达预定位置。

    • A projectile navigation system operable within an extremely high G-shock loading environment during the launch phase may include a set of Kalman filters configured to repeatedly calculate a navigational solution by solving a set of non-linear equations of motions of the projectile utilizing a current parameter vector, position, velocity, and attitude of the projectile. The system may include a suite of solid state sensors to calibrate the Kalman filter equations. If desired, the system may also include a satellite based positioning-determining (SBPD) attitude determination system configured to update the state of the host projectile by making real time attitude measurements of the projectile, and a parameter estimator configured to estimate and update a parameter vector of the host projectile. An external guidance and control processor may be used to generate guidance and control signals, enabling real time navigation of the host projectile.
