摘要： PURPOSE: To detect the positron of an excavator body accurately in real time by a constitution wherein a tracking/measuring unit tracks a tracking target on an excavator automatically and continuously and determines the position thereof. CONSTITUTION: A laser director 5 projecting a laser beam 6 is disposed at an appropriate position in a tunnel. A light wave range finder in a tracking/ measuring unit 7 measures the distance between the director 5 and the unit 7 for determining the positional coordinates of the unit 7. An excavator body 1 is provided with a gyro compass/biaxial clinometer 16, and a tracking target 4 having a tracking lamp and a reflective sheet. The unit 7 tracks the target 4 constantly and automatically and measures the vertical angle, horizontal angle and distance of the target 4 with respect to the unit 7 thus operating the positional coordinates of the target 4. The central coordinates of a truck turning body are then determined based on the attitude measurement data from the clinometer 16 and the tip position of a cutter drum is operated by numeric control thus managing the cutting position accurately.

摘要： PURPOSE: To provide a stereoscopic camera universal head for construction robot and an automatic tracking device with which the visual information of a remote construction robot can easily be provided to an operator. CONSTITUTION: When the operator vertically moves the head, a six-spindle magnetic sensor outputs a tilt signal and when the operator moves the head to swing it to right and left, a pan signal is outputted. While receiving that output signal, a controller 23 rotates a horizontal driving part 16 to perform the tilt move of left and right eye cameras 20 and 21 and rotates a vertical driving part 15 to perform the pan move of the left and right eye cameras 20 and 21. Besides, the stroke of the hydraulic actuator of a working machine is detected by a detecting means and while receiving a detecting signal detecting the position of the working machine, the controller 23 rotates the horizontal driving part 16 to perform the tilt move of the left and right eye cameras 20 and 21 and rotates the vertical driving part 15 to perform the pan move of the left and right eye cameras 20 and 21.
