Here is an example of a simple tool for reproducing via cloning. One robot
figures out if it is ready to reproduce (this example uses touching a ball)
and the other robot makes the babies.
The ball tracks the mouse for testing.
The sensors are for the yellow rectangle (the "mother") so you can more easily
test it.
Note that the newly created clone is right on top of its "mother". If you set
the Up Speed then you'll see more clearly what this is doing.
