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. In addition, a localization method using the map is also provided.
Abstract:
An omni-directional robot cleaner, composed of a platform and a plurality of driving units for driving and controlling the movement of the platform, in which the platform further comprises: a sensing unit, for obstacle detection; a cleaning unit, for collecting and removing dust and dirt; a processing unit, capable of receiving signals transmitted from the sensing unit while planning and mapping a travel path accordingly; and a power unit, for providing power to the omni-directional robot cleaner while managing the same. Moreover, each driving unit of the plural driving units is comprised of an omni-directional wheel and an actuator for driving the corresponding omni-directional wheel to rotate omni-directionally, by which the platform is enabled to move continuously while changing its moving direction simultaneously so as to free the robotic cleaner from the shortcomings of those conventional autonomous cleaner, such as poor maneuverability, poor mobility and insufficient degree-of-freedom regarding to the driving of the cleaner. Therefore, not only the operation mobility of the robotic cleaner is enhanced, but also the moving agility of the same is greatly improved.
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.
Abstract:
The present invention relates to a demolding method and device, being used for detaching a mold and a substrate after completing an imprinting process, in which the mold is forced to detach from the substrate partially and form a gap therebetween by inserting at least a blade module between the two, and thus, as air is sucked into the gap and the adhesion force of vacuum effect exerting between the mold and the substrate is eliminated, the blade module is further applied to detach the mold from the substrate completely.
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 (¼λ) 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. Optical systems using the present invention are simplified and capable of being portable. Thus a high sensitivity detection technique is achieved.
