At the Launch level the line : source devel_isolated/setup.bash

some problems on the blockly test with Burger

Hi,

when i carried out the turtlebot3_blockly with a burger ,i found some problems.

it can't execute the other blockly command except for the first and Burger can't stop when it run the first blockly command .

Additionally,only in the case of the use of python 2, the blockly command can be used.

thanks
