ROS Publish Msg - DJI ROS OSDK

Hi there,

I am trying to publish a message to a ROS topic. The topic is one of the ROS topics available in the DJI drone ROS OSDK. Please see image 1 below. I'd like to publish roll angle, pitch angle, yaw rate and z position commands to the corresponding ROS topic. I'm using a Bus create at the input of the Publish block. However, I get the error shown in the next images. Could you please advise how I may resolve this?

Thank you.

Ben

Instead of using a Bus Creator block, use a Blank Message block with the right message type (sensor_msgs/joy), and then use a Bus Assignment block to update individual signals in the bus.

Most of the ROS examples in the documentation or the Getting Started examples will show you what this looks like.
