  • Patent number: 6574536
    Abstract: A moving robot first moves straight in a first forward path. When encountering an obstacle such as shelf, the robot makes a U-turn to move straight in a backward path located with a prescribed distance away from the first forward path. When encountering another obstacle, the robot again makes a U-turn to move straight in a second forward path extending in the same direction as that of the first forward path but located with a distance away from the backward path. When the robot exceeding the point of the U-turn in the first forward path is detected during running in the second forward path, presence of a region where the robot has not run yet is recognized, and running in that region is carried out thereafter.

  • Patent number: 5998953
    Abstract: In order to improve the quality of the work of a robot that applies wax, a user enters the ambient environment data (temperature, wax concentration, and the like) of the robot via a controller prior to initiation of the work by the robot. According to the input data, the maximum time (drying time) T before another coat of wax is to be applied without degradation in quality is identified. A travel path is generated according to the time T. The travel is actually carried out according to the calculated path.

  • Patent number: 5717484
    Abstract: A first light receiving portion and a second light receiving portion are provided on the upper surface of a moving body having driving wheels at an interval of a prescribed distance in a plane. The first light receiving portion and the second light receiving portion rotate around the axis in the vertical direction. On the other hand, a first light emitting portion and a second light emitting portion are provided on the side face of a station serving as a reference station at an interval of a prescribed distance in a plane. The first and second light receiving portions carry out sampling while rotating, so that the quantity of light reception is changed according to the directivities of the first and second light receiving portions. When the peaks of the directivities of the first and second light receiving portions match the direction of the first light emitting portion or the second light emitting portion, the quantity of light reception is maximized.

  • Patent number: 5305233
    Abstract: A spectrophotometer utilizes a band-pass filter array for splitting incident light into a plurality of light components of different wavelengths, a plurality of silicon photodiodes for receiving the respective light components, and a memory for storing spectral sensitivity information. The spectral sensitivity information is obtained by integrating the spectral sensitivities of spectrodetectors relative to each sectionalized wavelength regions sectionally generated from a measurement wavelength region. Each of the spectrodetectors include a band-pass filter array and a silicon photodiode in combination. A central processing unit calculates simultaneous equations representing the relation between the output from each of the silicon photodiodes, the spectral sensitivity information stored in memory and the light intensity of the sectionalized wavelength region, to obtain the light intensity.
