Abstract: A multi-machine cooperation method, a scheduling device, and a multi-machine cooperation system are described. The multi-machine cooperation method includes: determining, by a first autonomous robot when detecting an abnormal condition during operation, whether the abnormal condition can be independently processed; and when the abnormal condition cannot be independently processed, sending, by the first autonomous robot, an assistance request to another device in an Internet of Things in which the first autonomous robot is located. In the specification, a multi-machine cooperation operation between autonomous robots or between an autonomous robot and another device can be implemented.

Abstract: A pixel value array is provided, which includes an examined pixel value. Several reference pixel values are each subtracted from the examined pixel value to obtain several differences. The sampling pixels of these reference pixel values are spatially adjacent to the sampling pixel of the examined pixel value. The reference and examined pixel values represent the same color. The differences are compared with a reference value. When the absolute values of the differences are all greater than the reference value, the examined pixel value is determined as being wrong.

Abstract: A method of making golf clubs of thermoplastic composite material is disclosed. The present method is characterized in that the composite material wound around a mandrel is consolidated by using a metal sheet. This method comprises the steps of: (a) providing a tapered mandrel, and wrapping the mandrel with at least a sheet of thermoplastic prepreg to form a laminated outer shell; (b) heating the thermoplastic prepreg to a molten state; (c) enclosing the laminated outer shell with at least a metal sheet, and heating the metal sheet and the laminated outer shell while constricting said metal sheet to thereby consolidate the molten prepreg to form a tubular body; and (d) releasing the metal sheet and withdrawing the mandrel from the tubular body.
