Ok. I solved my problem, I can read the current position calling:
rostopic echo svh_controller/channel_feedback
channel_targets (sensor_msgs/JointState)
Target position the channels (fingers) shall move to. Note that it is less performant to give targets for individual channels or a subset of the available DoF than providing it for all at once. If 8 channels are given instead of 9 the driver will send 8 packets instead of 1 which might influence serial device performance. Only the names and positions will be evaluated from the JointState message.

channel_feedback (sensor_msgs/JointState)
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?
you could send it with "rostopic pub ..." or write a node which publishes to channel_targets
