In a shocking turn of events, I've learned to hold the cameraphone sideways to capture more material with a better perspective. Control of 4 motors like this should give us 3 axes of movement. All that needs to be done is to assign the motors to an input, and possible solve the issue of snapback. Since this is being controlled in pulse-width modulation, there doesn't seem to be an evident way to move the arm without having it return to its primary position.
