Now it is time for a test run with the new controller.

The whole thing is nice and sturdy, and the kids understand what it is. 

You can check out the videos.

You'll notice that the kids like to press one button over and over again.   So they end up spinning the spindle to much, so it either flips over and up becomes down - or it gets tangled from being lifted too high.  Also, right now there is one button to open the claw and another to close it, so they tend to open or close it too far and it gets jammed.
 
I think that adding some endstop style switches and mabye some automation to simplify the controls would help.

This shows my 4 your old after she has been practicing.
