  • Patent number: 7835823
    Abstract: A medical robotic system comprises a number of components that may be monitored to determine their preventive maintenance needs by recording usage-related information for the monitored components into associated non-volatile memories. When usage of the component exceeds a specified usage threshold, the system displays a warning message on its display screen to have preventive maintenance performed for the component. If the usage continues without such maintenance and exceeds a higher usage threshold, the system displays an error message on its display screen and the system transitions into an error state during which medical procedures are not allowed to be performed. The usage-related information may also be communicated to a remote computer which gathers and processes usage-related information from a number of medical robotic systems to estimate resource requirements for timely performing preventive maintenance on the medical robotic systems, and anticipated service revenues from such maintenance.

  • Patent number: 7813837
    Abstract: A robot control system for controlling a position and an attitude of a robot head is provided with an operating head held by an operator and a sensor for detecting a position and an attitude of the operating head. An attitude recognition portion of the control means recognizes an initial attitude of the operating head when a control switch provided at the operating head is turned on, and acquires a displacement vector from the initial attitude by a change in the attitude of the operating head. An attitude conversion portion converts the displacement vector from the initial attitude to a displacement vector from the reference attitude corresponding to a predetermined reference attitude, and the control means makes the attitude of the robot head follow the displacement vector from the reference attitude. In whatever attitude the operator holds the operating head, the position and the attitude of the robot head can follow the change in the position and the attitude of the operating head.

  • Patent number: 7424341
    Abstract: A robot system efficiently performing an operation of moving a robot to close to and/or separate from a target point, such as teaching operation. A camera of a visual sensor is mounted to the robot such that a distal end of an end effector is seen within the field of view of the camera, and the end effector's distal end and a target position on an object are specified on a monitor screen. When an approach key is depressed, a target position is detected on an image, and a difference from a position of the end effector's distal end is calculated. Whether the difference is within an allowable range is checked. Depending on the result, an amount of robot motion is calculated, and the robot is operated. The processing is repeated until the depressed approach key is released. When a retreat key is depressed, the robot moves away from the object. The robot may be caused to stop using a distance sensor.

  • Patent number: 7409265
    Abstract: It is arranged such that displacement sensors (70) are installed at a position in or vicinity of elastic members (382), to generate outputs indicating a displacement of the floor contact end of a foot (22) relative to a second joint (18, 20), and a floor reaction force acting on the foot is calculated based on the outputs of the displacement sensors by using a model describing a relationship between the displacement and stress generated in the elastic members in response to the displacement, thereby enabling to achieve accurate calculation of the floor reaction force and more stable walking of a legged mobile robot (1). Further, a dual sensory system is constituted by combining different types of detectors, thereby enabling to enhance the detection accuracy. Furthermore, since it self-diagnoses whether abnormality or degradation occurs in the displacement sensors etc. and performs temperature compensation without using a temperature sensor, the detection accuracy can be further enhanced.

  • Patent number: 7403836
    Abstract: The automatic work apparatus extracts the target image of which photos are taken by the left and right CCD cameras, specifies the spatial position of the target and executes an operation to the target by the arm. Two regions, the central region and the peripheral ones, allocated to the image taken by the CCD camera so that if the target image stays in the peripheral region of the image then the cameras are rotated to take the target image in the central portion and the position determining module determines the spatial position of the target and then tasks are done for the targets. The relative distance from the target is adjusted by transfer equipment. This invention is applicable to an automatic work apparatus that can operate a predetermined operation for moving target and an automatic operation control program to carry out such operation.
