I had a variety of inchworms with a couple of other motors.
This motor works with the solar panel. It did not work with the light through the window
but did outside.
Also it could work with one motor used as a generator.

each axle
The pawl and ratchet are to be set so that both the front and the back
wheels roll only forward.
Different battery levels made the speed different.
