4) A robot is equipped with a GPS, which indicates the x coordinate and the y coordinate of the
robot position and a compass, which indicates the robot heading angle (the adjusted
quantities are as defined in lecture).
The robot starts out an initial position given by coordinates xi = 34 meters and yi = 51 meters
and an initial heading angle of 36 degrees. The robot should move to a final (goal) position given by
the coordinates xf = 73 meters and yr = 168 meters. Find the following:
a) Ax = change in x, Ay = change in y
b) required Goal robot heading angle OG
c) angle 40 through which the robot should spin (rotate on the spot) at the start of motion
d) d=straight line distance between the robot initial position and final (goal) location
