ROS Skill

ROS Skill implements a skill that shows how to publish images to an ROS topic via rosserial.


  1. Install ROS system and rosserial on your PC.

Building and running the example

Launch roscore on your PC:

$ roscore

To have your PC receive ROS messages from your ROBOT, execute the following command in a terminal on your PC:

$ rosrun rosserial_python tcp

Modify rosMasterIP inside of robot/src/rosdemoskill.go to point to your PC's IP.

You should now be ready to build, pack and run the Skill

$ mind build && mind pack && mind run

Once your Skill is running you can see the images being streamed to your PC by executing:

$ rosrun image_view image_view compressed   # for ros indigo
$ rosrun rqt_image_view rqt_image_view      # for ros kinetic

You might need to install compressed_image_transport.


This example Skill has only been tested on ROS indigo and kinetic.

If you need to add other message types than those already provided you can follow the official guide on how to generate rosserial_embedded linux libraries. Example:

cd <some_directory>
rm -rf ros_lib examples
rosrun rosserial_embeddedlinux .

Finally, put the ros_lib to robot/deps/include in skill folder.


rosserial uses 2 bytes to describe the length of the message, thus, the length of messages can not exceed 32767 bytes. However, you can try to write the sender and receiver part by yourself to support larger messages.

You can’t perform that action at this time.
