  • Patent number: 10241497
    Abstract: Control that is less likely to cause an overshoot is performed when an actual inertia value is yet to be determined. A development support apparatus sets a ratio of a position proportional gain to a velocity proportional gain to a value smaller than a ratio set when a servo driver has determined an actual inertia value of a load machine.

  • Patent number: 9752994
    Abstract: A measurement target is captured using two types of illumination patterns set such that only color features of specular objects change, the two images that are obtained are compared, and objects are identified as being specular objects or diffuse objects depending on whether the color features change markedly. At this time, the emission intensity distribution of each illumination pattern is devised such that specular lobe components that are included in reflected light are canceled out.
