TASK$-2$: Resetting the robot positions

Create a Python node that calls the $/$reset$\_$positions service of ROS Stage in order to return the robots back

to their initial positions when step A is accomplished for both robots, run this node in the terminal to

demonstrate the result.

C$.$ TASK$-3$: Creating service and message files

Recall that we created a ROS Python node $$movetogoal$2.$py$$ in the lecture as an exercise.

Create a service $($in Python$)$ that does the task of the $$steering$\_$angle$$ function in this code. The service

requires $4$ float parameters representing the coordinates of two points and returns the steering$\_$angle $($a float

value$).$ In the $$steering$\_$angle$$ function, instead of calling the function $$atan$2($goal$\_$pose.y$-$

$2$self.pose.y$,$goal$\_$pose.x$-$self.pose.x$),$ call your service to calculate the steering$\_$angle. The $$steering$\_$angle$$

function should return the result that the service provides.

$$

Submit your modified $$movetogoal$2.$py$$ code, srv file, msg file, and service node in Python.
