Launch Blockly web interface

Once the software package is setup there are a few commands to launch the Blockly web interface. Open terminal and type the following commands and leave the terminal running.

$ cd ~/blockly_ws
$ source devel_isolated/setup.bash
$ roslaunch turtlebot3_blockly turtlebot3_blockly.launch


To launch the web interface of blockly, you don’t necessarily have to start roscore but you should if you plan to connect TurtleBot3 and test it during development.

Open a web browser and type in the address bar. The Blockly web interface should open and will look like the image below.
