Hi there,

We are trying to control the gimbal on M300RTK through OSDK-ROS. From the sample node (https://github.com/dji-sdk/Onboard-SDK-ROS/blob/master/src/dji_osdk_ros/samples/gimbal_camera_control_node.cpp), we saw we can control by using the ros service. However, it seems the service is not called fast enough for us to have the gimbal tracking a moving object. Is there any way that we can use rostopic to control the gimbal?

Thanks!

And how fast do you need? Usually it runs on 10 or 20Hz, depending on drone. If you need faster, it's better to use the speed (angle/s) mode instead of absolute/relative degrees, which I guess you using. If you can calculate the speed of you object you tracking, you will be fine. It usually gets pretty smooth as well.
Edit: Add a pid-regulator to that, and I think it will track pretty fast.
