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.
