ROS and SONARS for OBSTACLE AVOIDANCE | Tutorial #6 | ROS and Raspberry Pi

Let's write our first OBSTACLE AVOIDANCE algorithm, using ROS Kinetic, a Raspberry Pi and our Donkey Car. Thanks to 3 cheap sonar sensors we define new nodes for creating an obstacle avoidance action, to be fused with the controls coming from our laptop.

*** Propose your own algorithm and be part of my next shout out! **

*** This is a ROS tutorial series for beginners that uses a Raspberry Pi and a cheap RC Car ***
