    摘要: A robot system includes camera, a distance direction sensor and a controller. The controller is configured to store a plurality of instruction images obtained as a target of the real-time image at each of a plurality of discrete instruction points provided on a predetermined running path. The controller is configured to switch, on the basis of predetermined switching conditions, between an image guidance mode in which the controller controls a running subsystem on the basis of a comparison result between the real-time image and the instruction image, and a measurement distance guidance mode in which the controller controls the running subsystem on the basis of a detection result of the distance direction sensor.

    摘要: An industrial robot is used to assemble a part to a predetermined location on a randomly moving workpiece. The workpiece may be an automobile on an assembly line and the part may be a wheel (a tire mounted on a rim) to be assembled on one of the wheel hubs of the automobile. The robot has mounted on it a camera, a force sensor and a gripper to grip the part. After the robot grips the part, signals from both the force sensor and vision are used by a computing device to move the robot to a position where the robot can assemble the part to the predetermined location on the workpiece. The computing device can be the robot controller or a separate device such as a PC that is connected to the controller.

The method comprises the steps of: (a) Evaluating pre-action output information of said sensor means in order to detect the position of a pattern in the input space of the sensor means; (b) Deciding on a targeted post-action position of said pattern in the input space of said sensor means; (c) Defining a command for the actuator means by mapping any deviation of the pre-action position and the targeted post-action position in the input space coordinates of the sensor-means to actuator control coordinates using a predefined mapping function; (d) Orienting/Positioning the sensor means by the actuator means according to the defined command in order to carry out an orienting/positioning action; (e) Detecting the real post-action position of the patterns in the input space of said sensor means; (f) Detecting external motion of the pattern; and (g) Adapting the mapping function used in step (c), wherein steps (a) to (g) are repeated using the respectively adapted mapping function.

The robot manipulator comprises a movable robotic arm having an effector for handling an object, a drive system for moving the arm in response to arm input signals, sensors for sensing the position of the arm and for generating arm output signals which characterize the dynamic motion behavior of the arm, and a vid=eo camera carried by the arm. The camera responds to motion of the moving object within the field of view of the camera. The video monitor receives an input video signal from the video camera, for displaying an image of the object to a human operator. The image processor is responsive to the output signal of the camera, and is capable of acquiring and pre-processing an image of the object on a frame by frame basis. The hand control is capable of generating a hand control output signal in response to input from a human operator. The computer generates arm input signals and is disposed between the hand control means, the robot manipulator, and image processor. The computer receives (i) output signals from the image processor and (ii) the arm output signals and (iii) the hand control output signal and generates arm input signals in response to the received signals whereby the arm tracks the motion of the object.
