Hi there, I cannot make my turtlebot3 move.

I followed the Turtlebot3 emanual ( http://emanual.robotis.com/docs/en/pl... ), using Linux based on Raspbian for my turtlebot and the Matlab tutorial 'Getting started with a real turtlebot' ( https://de.mathworks.com/help/robotic... ).

I'm using ROS 1.12.12 on my Turtlebot3 Waffle Pi with OpenCR v1.1.2 and am communicating throught Matlab R2018a (with ROSTtoolbox) on a lenovo thinkpad x121e with win 7 ultimate x64 system. Using ethernet cable, all firewalls deactivated.

Turtlebot3 ip is, Matlab laptop uses, they ping each other.

I already checked https://answers.ros.org/question/2727... but this didn't solve my problem.

I am able to recieve compressed images from the pi camera.

What I do:

Starting terminal on Turtlebot3

pi@lane_assist:~ $ sudo nano ~/.bashrc

The last 3 lines of this file are

export TURTLEBOT3_MODEL=waffle_pi

Then I'm launching ROS on Turtlebot3

pi@lane_assist:~ $ roslaunch turtlebot3_bringup turtlebot3_robot.launch
