Abstract: A method for calculating a starting point includes the following. A first coordinate system and a second coordinate system are established. The first coordinate system includes a CX-axis and is a coordinate system for a picture of a part to be processed. The picture of the part to be processed is captured. A first coordinate of a light spot on the CX-axis is obtained based on the picture. The light spot is formed by irradiating on the part to be processed by light. The second coordinate of the light spot in the second coordinate system is calculated based on the first coordinate as the starting point for processing. The method further relates to a device for laser processing and a non-transitory computer-readable storage medium.

Abstract: A multi-rotor aircraft (100) is provided, comprising: a main aircraft assembly (10) comprising a first magnetic medium (13), a main housing (11), and a control motherboard accommodated in the main housing (11), wherein the first magnetic medium (13) is provided on the main housing (11), a slot (1120) is further provided on the main housing (11), and a connection point of the control motherboard is provided in the slot (1120); and a plurality of rotor systems (20), wherein each of the plurality of rotor systems comprises a second magnetic medium (23), a rotor mechanism (21), and a rotor protection cover (22) that is of a hollow annular structure and is fixed outside the rotor mechanism (21), wherein the second magnetic medium (23) is fixed to the rotor protection cover (22) and attracting the first magnetic medium (13), and a pin (2200) matching the slot (1120) is further provided on the rotor protection cover (22).

Abstract: The present invention provides a method and apparatus for converting building block programming into a program code. The method comprises: setting up building blocks including input parameters, wherein the building blocks mean statement units in the building block programming; setting up a configuration file for converting the building blocks into program codes, wherein the configuration file comprises a plurality of code regions and subprogram codes respectively set up in the plurality of code regions; and converting the building blocks into corresponding program codes according to the subprogram codes and the input parameters respectively set up in the plurality of code regions. The problem in the prior art that the building block programming cannot be applied to different electronic modules is solved.
