39,021 PointsHi Surya,
You're almost there. What you're doing in each case, though, is creating a new point with specific coordinates. Instead, what you should be doing is changing the x and y coordinates of the robot's location. For example, to move the robot right, you would set:
self.location.x += 1
Does that make sense? I think you can take it from there!
Best,
-Greg
