Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for detecting a mobile unit allowing to detect a mobile unit stably, even under the condition where the environment in the monitoring area fluctuates and the condition where the reference plane for detecting the mobile unit cannot be set to be a plane.
SOLUTION: A background distance generation section 21, on the basis of measurement results of a laser radar 10, generates a background distance map, indicating the distance information from the laser radar 10 in a detection area to an object in the background. A mobile unit detecting section 23 detects a mobile unit in the detection area from the difference between the distance information of the background distance map stored in a background distance map memory 22, in advance, and the measurement results of the laser radar 10.

Abstract: PURPOSE:To allow a moving robot containing a welding bead sensor to run actually along a welding line by taking into consideration the quantity of the displacement of a bogie coordi nate system as the robot travels. CONSTITUTION:For every one sampling interval from the state of the scanning of a bead sensor 15 to the end of the sampling of bead position data, the distances 11 and 12 between two points on a welding line, which are obtained from the bead sensor, and the center line of a bogie, which has been already known, the travel DELTAVL, of the robot, which is obtained from a planimeter, and the attitude angle Va of the robot, which is obtained from a vertical sensor 56, are input together as a set, and the sampled distance data 11 and 12 are transformed into the values at the very time when the sampling has been completed, and accordingly a linear equation for the welding line: ax+b is obtained by a least square method together with the data already obtained in the previous sessions. In the travel during the next one sampling interval, the equation obtained in the last session is coordinate-transformed by the travel DELTAV1 of the robot so as to use as the estimate of the welding line equation, so that the robot is controlled by controlling the attitude angle Va to follow the welding line in such a way that the distance between the welding line and the center of the bogie becomes zero based on the obtained relationship between the robot and the welding line.

CONSTITUTION:The distances L1 and L2 to the fillet weld line 12 are calculated by the supersonic sensors 7 and 8 on right and left provided to the carriage 1 supported by wheels driven back and forth and right and left by independent driving motors 6 and the distance L3 and the inclination in the direction of a central flaw detection probe 11 are calculated by an arithmetic unit. As a result, the carriage 1 is induced to the prescribed distance A is the orthogonal direction to the weld line 12 by the automatic control. The flaw detection prove 11 is allowed to approach the weld line 12 with the high accuracy and the flaw detection is rationalized and its efficiency is increased automatically.

Abstract: PROBLEM TO BE SOLVED: To provide unloader equipment capable of being handled easily in an operation assistance. SOLUTION: This unloader equipment is formed so that, when a scraping and transport device is moved to the outside of a specified hatch coaming, a shape data on the specified hatch coaming is held as a shape signal 29s in a data storage device 30, and an instruction signal 32s to interrupt the calculation of the relative position of the hatch coaming to the scraping and transport device is output from a position judging device 32 to a relative position calculator 31. When the shape data of the other hatch coaming is given to the data storage device 30 when the scraping and transport device is moved into the other hatch coaming, an instruction signal 32s to re-start the calculation of the relative position of the hatch coaming to the scraping and transport device is output from a position judgment device 32 to the relative position calculator 31, and the hatch coaming which receives the shape data automatically performs an operating assistance for an incidental hold.

Abstract: PURPOSE:To obtain a weld bead position sensor capable of detecting a weld bead position necessary for the running of an ultrasonic flaw detection device along a weld bead by electrical scanning. CONSTITUTION:A large number of coils 22 are densely arranged zigzag or linearly on a plane in the direction crossing a weld line direction and three coils are successively selected as a unit for exciting coils and detection coils L01-L03 while the coils 22 are shifted one at a time from one end thereof by a changeover switch and the region corresponding to the coil group 23 is scanned to subject a weld bead position to eddy current flaw detection. From one scanning detection waveform or the waveform showing a weld bead shape obtained by further integrating said waveform, the weld bead position is detected.
