Abstract: The disclosure provides a displaying substrate, a manufacturing method thereof, and a display panel, and relates to the technical field of display. The displaying substrate comprises a first supporting base (1), plurality of vibrating element modules (2), and a display module (3). The display module (3) comprises display units (31), connecting units (32) and hollowed-out units (33). Each connecting unit (32) is located between two adjacent display units (31). Each hollowed-out unit (33) is located between two adjacent display units (31) except an area where the corresponding connecting unit (32) is located. The hollowed-out units (33) are provided with cavities (40) corresponding to the vibrating element modules (2). Orthographic projections of the hollowed-out units (33) on a reference plane cover orthographic projections of the vibrating element modules (2) on the reference plane. The vibrating element modules (2) and the cavities (40) form a transducer.

Abstract: Embodiments of the present application relate to the field of virtual simulation technologies, and provide a robot offset simulation method and apparatus, a robot, an electronic device, and a storage medium. The robot offset simulation method includes: establishing a reference path for a virtual robot in simulation software, where the reference path is a path along which the virtual robot moves to transfer a reference object from a preset starting point to a destination location and then returns to the preset starting point; receiving location information of a target object that is sent by a PLC; determining an offset of the virtual robot based on the location information, where the offset is a location offset of the target object relative to the reference object; and controlling, based on the reference path and the offset, the virtual robot to move to transfer the target object.

Abstract: A programmable logic controller (PLC) testing system includes a virtual device simulating a field real device, a testing tool configured to start a preset test case to inject a fault into the virtual device, and a PLC device configured to execute a preset fault processing logic in response to receiving a fault signal produced by the virtual device simulating a field fault according to the injected fault. The preset fault processing logic includes sending alarm information to the virtual device. The testing tool is further configured to detect whether the alarm information forwarded by the virtual device meets expectation of injecting the fault by the preset test case to test whether the fault processing logic of the PLC device is normal.
