After the completion of this module the students will be able to:

review Edpy code for various events handling
create code to detect obstacles using Edison robot sensors
extend the code to avoid obstacles

8.4.1 - Obstacle avoidance

Write the following code to Edpy and program edison to avoid obstacles

#-------------Setup----------------

import Ed

Ed.EdisonVersion = Ed.V2

Ed.DistanceUnits = Ed.CM
Ed.Tempo = Ed.TEMPO_MEDIUM

#--------Your code below-----------

#turn on obstacle detection
Ed.ObstacleDetectionBeam(Ed.ON)



Ed.Drive(Ed.FORWARD, Ed.SPEED_5, Ed.DISTANCE_UNLIMITED)
while Ed.ReadObstacleDetection() != Ed.OBSTACLE_AHEAD:
    pass
Ed.Drive(Ed.SPIN_RIGHT,Ed.SPEED_5,180)
Ed.Drive(Ed.FORWARD, Ed.SPEED_5, 10)

You can download the code from here

How could you improve this program?

Can you modify the code so that the robot behaves differently when it detects an obstacle ahead, left or right?
