source /opt/ros/$ROS_DISTRO/setup.bash git clone -b $ROS_DISTRO https://github.com/micro-ROS/micro_ros_setup.git src/micro_ros_setup rosdep update && rosdep install --from-path src --ignore-src -y colcon build source install/local_setup.bash...
During that time, the colcon plugin will install rosdep and use it to determine the dependencies specified in the package.xml of the packages, fetching and unpacking them into your snap. At the end, the result is squashed into a .snap file. Test the Snap To install the snap we just ...

To install ros_control and some controllers run the following command in your terminal: $sudo apt-get install ros-$ROS_DISTRO-ros-control ros-$ROS_DISTRO-ros-controllers Modifying the URDF I will now describe the parts that have to be added to the URDF in oder to use it together ...
And you must have a free terminal ready to use again: user@computer:~$ Step 3 – ROS Dependencies We are almost there! ROS commandsClientcan also manage dependencies for you androsdepis the one in charge of it. That’s why we have to initializerosdep. It goes like this: ...
