The purpose of the moving platform is to hold the instruments below the load while performing the user-programmed motions that simulate friction. The design consists of 2 primary layers, each corresponding to motion in one direction, and the pegboard component for instrument attachments.

Both stepper motors are controlled using one Arduino. Serial commands are available for simple motions, and complex paths have individual,  dedicated scripts. Here are some sample motion paths for the platform system, varying in levels of complexity.

The setup may also be integrated into other tests, including the speed test. This test should be run without the device attached to the E3000 test frame. A camera should be positioned and stabilized directly above the platform. 4 locations can be marked with colored stickers. These markers should serve as the known positions. The platform should also be marked with stickers at four corners. Take photos of the initial setup before motion. Motion according to a programmed path for a simple square (or alternative shape) should be recorded. The video can be analyzed to determine if the platform was at the specified locations. This test should be done at multiple speeds and loads if possible.
