  • Patent number: 8588471
    Abstract: A mapping method is provided. The environment is scanned to obtain depth information of environmental obstacles. The image of the environment is captured to generate an image plane. The depth information of environmental obstacles is projected onto the image plane, so as to obtain projection positions. At least one feature vector is calculated from a predetermined range around each projection position. The environmental obstacle depth information and the environmental feature vector are merged to generate a sub-map at a certain time point. Sub-maps at all time points are combined to generate a map.

  • Patent number: 8160746
    Abstract: System and method for graphically allocating robot's working space are provided. The system includes an image extractor, a task-allocating server and a robot. A graphic user interface (GUI) of the task-allocating server includes a robot's working scene area, a space attribute allocating area and a robot's task area. Thus, a user assigns one certain space area in the robot's working scene area with a “wall” attribute, or another space area with a “charging station” attribute. Meanwhile, by using the GUI, the user directly assigns the robot to execute a specific task at a certain area. Hence, the user or remote controller facilitates the robot to provide safer and more effective service through his/her environment recognition.

  • Patent number: 7636502
    Abstract: An optical waveguide bio-sensing device, comprising: a monochromatic light source, a beam splitter, a grating chip with a sub-wavelength grating structure and a sensor. Moreover, in order to enhance the sensitivity of the system using the optical waveguide bio-sensing device, a light concentrating element or a quarter waveplate (¼?) is arranged in the optical path during detection. When the grating chip is not coated with a layer of biochemical substance corresponding to a monochrome light emitted from the monochromatic light source, a reflected light of a specific narrow wavelength is reflected by a specific angle as a surface plasmon resonant effect caused by waveguide coupling is excited by the incidence of the monochrome light to the grating chip through the beam splitter; otherwise, there will be little or no reflection. Accordingly, the optical waveguide bio-sensing device can detect bio-molecular interactions, reaction rate and/or molecular dynamics without any labeling in real time.
