Example 8 using abs

Simulation

Real Life

What does the code do?

In this code the robot moves forward until abs < distance, then drives back to original position.

Functions Used

cmpc( clear_motor_position_counter)

abs( absolute )

gmpc( get_motor_position_counter)

mav( motor port, velocity)

msleep( distance in ms)

Function Implementation

#!/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 main():
       drive(1000, 500)
       drive(1000, -300)

if __name__ == "__main__":
   main()

Rookie Tips

You can make multiple define(func) in a code inorder to make your code more organised!
