Merge joint states from multiple sources [closed]

Hello All,

I have the following setup: A UR5 robot and two maxon motors combine to form a robot. The robot, and the two maxon motors publish their current states on different topics. I need to merge all these topics and publish to /joint_states so that robot state publisher and moveit can consume it. How would I do this?

Thank You, Nihal

I've closed this as a duplicate of #q31956. While the mentioned HW is (obviously) different, the problem stated is the same, and the solution is usable here as well.

There is no need to create a custom node for this.

Hi,

A simple idea would be to create a node that subscribe to all of those topics. Then this new node would merge them in a new sensor_msgs/JointState message that can be afterward published on the topic /joint_states !

Hope it helps !
