    摘要: The characteristics of actuators themselves and the characteristics of controllers for the actuators are dynamically or statically controlled to achieve stable and highly efficient movements. In a stage in which a leg in the flight state is uplifted such that the reactive force from the floor received by the foot sole of the leg is zero, the characteristics of the respective actuators for the knee joint pitch axis and the ankle pitch and roll axes of the leg in the flight state are set for decreasing the low range gain, increasing the quantity of phase lead and for decreasing the viscous resistance of the actuators, in order to impart mechanical passiveness and fast response characteristics. The followup control for the high frequency range may be achieved as the force of impact at the instant of touchdown is buffered.

    摘要: To appropriately detect overload which may break a motor or deform a body and reduce the overload in the motor. The DC component of a load torque is derived from the sum of absolute values of a torque applied to a link connected to the output shaft of a motor and the generated torque of the motor, and it is determined that overload has been applied when the DC component exceeds a first threshold value for a prescribed period of time or longer. In addition, considering such a characteristic that the variation of energy applied to the output shaft of a motor is in proportion to a product of the torque and the angular velocity of the motor, the AC component of the load torque is detected based on the variation of energy, and it is predicted that overload will be applied when the AC component exceeds a second threshold value.

    摘要: A disk-type recording medium is carried by a disk carrying section and accommodated into one of layered accommodation shelves of a disk accommodation section. A memory stores position information of the disk carrying section with respect to the accommodation shelves. A controller controls the disk carrying section in accordance with the stored position information to move to a position corresponding to each accommodation shelf. A stopping state detection section includes a light emitting element and a light receiving element provided on the disk carrying section adjacent the disk accommodation section and detects a stopping state of the disk carrying section with respect to each accommodation shelf based on a received light amount of the light receiving element depending upon a state of a light intercepting disk which is transferred between the disk carrying section and the accommodation shelf. An updating section determines an optimum stop position of the disk carrying section with respect to each accommodation shelf in response to the detected stopping state and updates the position information stored in the memory with the position information corresponding to the optimum stop position.

    摘要: In a mobile robot, the actuator characteristics are dynamically or statically controlled, during motions of an entire robot body in the course of falldown or descent, to realize stable highly efficient motions. In each stage of the falldown motions, the characteristics of each joint site taking part in controlling the stable area are set so that the low range gain is low, the quantity of phase lead is large and the viscous resistance of the motor is large, in such a manner that these joint sites may be positioned to high accuracy in a controller manner to increase orientation stability. This assures the positioning accuracy of the joints as main component for controlling the quantity ΔS/Δt as a reference in controlling the falldown motions of the robot body to increase the motion stability.
