What does this code do?
-----------------------
In this code the robot moves forward until abs < distance, then rotates right by 180 degrees and finally rotates
left by 360 degrees.

Functions Used
--------------
cmpc( clear_motor_postition_counter )

abs(absolute)

gmpc(get_motor_position_counter)

mav(motor port, velocity)

msleep( distance in ms)

Function Implementation
***********************

.. code-block:: python
   :linenos:

   #!/usr/bin/python3
   import os, sys
   sys.path.append("/usr/lib")
   from kipr import*

   def drive(distance, speed):
       cmpc(0)
       while abs(gmpc(0)) < distance:
           mav(0, speed)
           mav(3, speed)
       mav(0, 0)
       mav(3, 0)
       msleep(20)

   def turn_right(distance, speed):
       cmpc(3)
       while gmpc(3) < distance:
           mav(0, -speed)
           mav(0, speed)
       mav(0, 0)
       mav(0, 0)
       msleep(20)

   def turn_left(distance, speed):
       cmpc(0)
       while gmpc(0) < distance:
           mav(0, -speed)
           mav(0, speed)
       mav(0, 0)
       mav(0, 0)
       msleep(20)
