I used the rubber bands to hold my servo motors, and they were easier to attach to the longer cleats. I may have to move them further apart to increase tension. When I sized the wheels that attached to the servo horns, I assumed I would have to trim off the tips so they wouldn't scrape the user, but they were fine out of the box, which is excellent news since that will be ones less thing for folks to worry about when constructing. The wheels were actually too small. When I took measurements, I based their diameter on the center of the servo motor, but I should have accounted for the rotation, which brings the axel further away from the user.

Once my motors were mounted and I attached the small wheels, I dug out a servo tester that can send timing signals based on a potentiometer or automatically swing left and right. I needed power, but I loaned out my USB to header adapter, so I soldered a couple of test leads to a 9V-style connector and plugged it onto a 4@AA battery holder. The movement showed me what to expect when connecting a microcontroller, but I need larger wheels. I cut the first ones from the platform where the motors and battery rest so there might not be room in the next revision.
