For your quest on making on the device to support a PSA system and move it, we eighth graders from Team A, have produced and idea. For this idea we are going to obtain a crane machine from one of are groupmates. With this machine we will alter the size of the claw to take hold of the PSA. And move it up and down as well as left and right. We may also be forced to alter the size of the rail the crane runs on, so it will be able to move far enough. In conclusion we feel our machine will succeed in the challenge. A preliminary diagram is attached.

The environment within which we will test our device depends upon whther or not the memory on the PSA is stored magnetically. If not, we are thinking about testing this between two powerful magnets with opposite poles repelling one another in order to suspend the PSA.
