[bug] A* pathfinding will sometimes show up inside wall

[clay-arras]

description: the pathfinding will sometimes show up inside the wall. Figure out why and fix it.

notes:

• The robot's state is tracked by self.robot.hull.position in robot_obstacles.py and by the self.maze object in the same file.
• When the robot moves, it maps the self.maze to the rendering screen, and finds the closest tile on self.maze
• self.maze is a 2D array, in which 3 represents a wall, 0 represents floor, and 1 and 2 represent the target and the robot.

ideas: it probably has something to do with the way that the state is stored
