$[$For this question submit the following: a $.$slx $($Simulink$)$ file called q$4.$slx$,$ further$].$ Let the initial co$-$ordinates of your robot be $(x,y)=(5,-1),$ and the initial orientation $=$ radians. The robot is to navigate to point $(-1,7).$ Use two PID controllers as discussed in class to first correct the angle, and then engage distance based speed control. If the error in the heading angle exceeds $0\mathrm{.}01$ then you must reengage heading$-$angle control, then upon correcting the heading $-$ disengage heading control and re$-$engage distance based speed control. The simulation must continue until the distance between the robot's current position and goal position drops below $0\mathrm{.}1$ units. Use the SimulinkRobotmodel.slx file, and the BasicPID.slx file to get started with PID controllers, and the robot model in Simulink. You must generate plots within Simulink that show the robot position converging to the goal, and also provide appropriate scopes for viewing the heading angle convergence. $(10$ points$)[$Completely successful completion of this question provides $1$ bonus point towards your final exam$]$
