Problem statement for Exercise 2:

Ex 2A - create a Node that will move the turtle ( in any direction ) | it should displace from its original position
Ex 2B - create a Node that will move the turtle to create a SQUARE , TRIANGLE , 5 POINTER STAR | VIA OPEN LOOP | VIA CLOSED LOOP
Ex 2C - create a small application where User will give inputs to draw a shape | all nodes to be started via launch file

Ex2A: Solution: THis is addressed in the python file turtlesim_move.py

Ex2B: Solution: This is partially achieved in the following python files:
a) Movement along a square (open loop - which means without any feedback loop) - turtlesim_square_move.py
b) Movement along a circle (open loop - which means without any feedback loop) - turtlesim_circle_move.py
c) Movement along a triangle (open loop - which means without any feedback loop) - turtlesim_triangle_move.py
d) Movement along a 5 Pointer Star - not coded
e) Movement along a square (closed loop - which means with feedback using the Pose message) - turtlesim_square_move_closed3.py
f) Movement along a Circle / Triangle (closed loop) - not coded

Ex 2C: Solution: THis is addressed in the python file userinput.py

• this internally instantiates the nodes from a), b), c), e) from Ex2B
  
• currently launch file is not working.
