Conveyor belt and related peripheral devices to a virtual sensor. , To produce, in one example a conveyor belt, after the work on the conveyor belt when being conveyed away need for a new robot for handling a workpiece. When the workpiece reaches a certain point on the robot system to give the workpiece run a sensor signal, so that the robot according to the process required to provide for the pixel element Porter workpiece handling robot system is placed indicated in the position. a robotic handling device in RobotStudio dynamic effects simulation creating plays an extremely important role [15]. Intelligent components in their software can achieve animation effects. added, in one example belt assembly intelligent first assembly, such as the body subassembly, the assembly operation of the motion attribute set conveyor belt limit sensor; Resetting connection attribute of each sub-assembly, then creating Smart conveyor assembly the necessary I / O signals, for signal interaction with the smart sub-assembly, and finally the correlation between the signal and the Smart robot assembly signal.
