Professor Sergey Bereg gave Mindy many ideas on how we can have different
templates so we can compare them. Mindy is working on different
configuration of robots.
Does push strategy always work? Of course not, so Mindy is trying to
show some examples when push strategy does not work.
For example, what if there is a not moving robot at the bottom of
another robot that needs to be pushed down to move forward?
Mindy will show the template soon.
