  • Patent number: 10739781
    Abstract: The present disclosure provides a method, apparatus, and terminal device for cliff detection. The method includes: obtaining a detection distance matrix of distances between a camera of a target robot and a ground within a preset detection angle range collected by the camera; obtaining a difference matrix obtained by subtracting a theoretical distance matrix from the detection distance matrix; counting an amount of elements in the difference matrix being greater than a preset first threshold; and determining a cliff is detected if the counted amount of the elements is greater than a preset second threshold. Through the overall consideration of the distance matrix of the distances within the detection angle range, even if a certain part of the ground changes its external conditions such as the color depth and the lightness, the influences on the overall detection result is extremely limited, which makes the detection result more accurate and reliable.

  • Publication number: 20190324470
    Abstract: The present disclosure relates to robot technology, and particularly to a method, a device, and a robot for identifying charging station. The method includes: first, obtaining scanning data produced by a radar of the robot; then, determining whether an arc-shaped object exists in a scanning range of the radar of the robot based on the scanning data; finally, in response to determining that the arc-shaped object exists in the scanning range of the robot, determining that the arc-shaped object is a charging station. Compared with the prior art, the present disclosure substitutes the arc identification for the conventional concave-convex structure identification. Since the surface of the arc is relatively smooth, the data jumps at the intersection of the cross-section will not occur, hence the accuracy of charging station identification can be greatly improved.

  • Publication number: 20190291095
    Abstract: An amphoteric dissociation ion exchange separation medium, the surface of which is an amphoteric dissociation covalently-modified layer. When an environmental pH value is lower than the isoelectric point, pIm, of the covalently-modified layer, the type of net charges on the surface of the covalently-modified layer is positive and the separation medium has the properties of an anion exchanger; when the environmental pH value is higher than the pIm, the type of net charges on the covalently-modified layer surface is negative and the separation medium has the properties of a cation exchanger. The separation medium has the properties of an anion exchanger and a cation exchanger at both sides of the pIm, respectively. The pH of an eluent can be adjusted to allow the separation medium surface and the target substance to have the same type of net charges, so that the target substance can be released by electrostatic repulsion.
