channel_feedback (sensor_msgs/JointState)

Current position of the channels (fingers).

Comment by Alba on 2015-04-27:
Yes, I know that I can use channel_feedback, but I don't know how I can use it, because I try calling: rostopic echo svh_controller/channel_feedback and it prints messages to screen, but how I can use the current data to update the channel_targets?

Comment by inflo on 2015-04-27:
you could send it with "rostopic pub ..." or write a node which publishes to channel_targets

Answer 1

Ok. I solved my problem, I can read the current position calling:

rostopic echo svh_controller/channel_feedback
