Reproduction via cloning
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.
