About Application Layer Protocol Definition

Why do you need an application layer The transport layer provides end-to-end communication services for the application process, but different communication rules are required between different network processes, so the application layer is also required above the transport layer. Application layer protocol definition: Type of packets exchanged by the application process, request or response? Syntax […]

How KUKA Robotic Vision Grasping Works

First, the trajectory of the robot must be established as the basic robot programming trajectory. The visual grasping is mainly realized by changing the TOOL coordinate system or the BASE coordinate system of the robot. The change of the position of the object is mainly the change of the X, Y, Z direction of its […]
