This is a fast robot. It moves at twice the speed of the player and the
slow robot. Like the slow robot 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't outrun it so you have to out-maneuver it and get it to collide
with another robot or a scrap heap to destroy it. Antimatter also
destroys a fast robot if it is adjacent to the player.
