Method and device for generating a robot stacking point location and computer readable memory
Lei Liangwei
- 19 Feb 2019
Abstract: The invention provides a method and device for generating a robot stacking point location and a computer readable memory. The method includes the steps that a stack type generation instruction input by a user is received, the stack type generation instruction is provided with a stack type template and a stack type parameter, and according to the stack type template and the stack type parameter, acorresponding goods placement stack type is generated; a tray basic parameter set by the user is obtained, the tray basic parameter includes the tray size and the size, the number of layers and the gap of goods to be placed on a tray; the relative position relationship between a robot and the tray is obtained, the tray position in a robot visual coordinate system is calibrated, and a virtual traycoordinate system is established; and according to the goods placement stack type, the tray basic parameter and the calibrated tray position, coordinates of goods placement points in the virtual traycoordinate system are calculated. According to the method and device for generating a robot stacking point location and the computer readable memory, complex placement of the goods can be realized.
