     Any other important information: My second robot had to 
be bigger. I needed larger pieces and the little windup artist 
could only paint for a few inches until it needed to be wound up 
again. That is when I adapted a remote controlled car into 
another type of windup painter. This one used the drive motor 
to power the windup motor's  gearbox. The gear box gave me 
four rotating shafts that operated the four little feet. 
But adjusting the length of the feet and the crank diameter 
The gearbox caused the robot to have a struggled walk.  The 
new motorized version was quite a bit heavier and used a 
automatic loading brush. The process yielded a good 
operating machine along the lines of the previous windup artist.
