A robot B wants to cross a road, while another robot A is moving from left to right. (Fig 1.2) Assuming that each robot can determine the (x, y) coordinates of both the robots, outline the program for each robot, so that they do not collide with each other. You can assume that (i) the clocks are synchronized, and (ii) the robots advance in discrete steps --- with each tick of the clock, they move one foot at a time
