This is a slow robot. It moves at the same rate as the player. It is a
single minded creature which always tries to take the shortest path to
the player. It does this by moving at an angle until it is in the same
row or column as the player on the playing field and then it moves in a
straight line toward the player in that row or column.
You can destroy it by maneuvering so that it collides with another robot
or with a scrap heap. Antimatter also destroys a slow robot if it is
adjacent to the player.
