The Pickit processor is the computer on which the Pickit software is installed. It is responsible for doing all calculations to detect your objects in a 3D point cloud and send the coordinates to the robot for picking. The current Pickit processor is actually the third hardware generation. The following articles give a description of these three versions:
Pickit processor 3.0 that applies to users who directly acquired a Pickit 3.0 system or later.
Pickit processor 2.0 that applies to users with an existing Pickit 2.0 system upgraded to the Pickit 3.X software.
Read this article to learn how to set up the processor in your picking application.
