•

4.4 Obstacle Avoidance
In this project, PiSloth will use an ultrasonic module to detect obstacles in front. When PiSloth detects an obstacle, it
will send a signal and look for another direction to move forward.
Run the Code
cd

home
/
pi
/
pisloth
/
examples
sudo python3 avoid
.
py
After the code runs, PiSloth will walk forward. If it detects that the distance of the obstacle ahead is less than 10cm, it
will stop and sound a warning, then turn left and stop. If there is no obstacle in the direction after turning left or the
obstacle distance is greater than 10, it will continue to move forward.
Code
Note:
You can
Modify/Reset/Copy/Run/Stop
the code below. But before that, you need to go to source code path
like
