1. Produce a motion platform capable of linear, X-Y motion to simulate friction.

2. Platform must withstand loads applied during a wear test.

3. The system should integrate with NuVasive’s existing testing equipment.

4. Accommodate various instrument types, shapes, and sizes.

A few of the constraints to our design are listed below:

• Our system needed to fit within the existing test frame, so a maximum size of 420 x 420 mm.

• The motor torque needed to be high enough to produce speeds of roughly 10 cm/s while enduring a load of approximately 5N.

• Convenient for a user to set up.

• Accommodating the three provided instrument types, so the fixtures could be expanded to multiple instruments.

The following figure shows our Gantt chart with assigned team roles and responsibilities to complete this project.
