The first platform design has a slider that allows the user to easily place their testing object and secure it for testing. This feature on the platform will allow for more room and space for testing. Since the placement of the object is important for testing, this platform feature will allow for more accurate testing. This feature also limits how much the operator has to adjust before testing.

This platform design has a differing slider. The design of the slider allowed for the testing object to be encased in the platform. The functionality of this platform encases the object within the inner edge of the platform and the slider edge as the slider moves into the platform. It restricts movement of the testing object. 

The motor casing will prevent any items from falling into the motors that move the platform up and down for testing. In this design, the casing is attached by hinges and allows the user to open and close the casing easily if there were a need for any adjustments or modifications needed to be made.
