Gripper joint positions/velocities

[Victeldo]

I'm working on a sim-to-real project where I need to pass in the Kinova Gen 3's sensor data, which includes the gripper sensor data (Robot IQ 2f 85). I need to get the positions/velocities of each of the 6 joints of the gripper. However, via the

rospy.wait_for_message("/" + self.robot_name + "/joint_states", JointState)

I'm only able to get just one position/velocity value, which I assume just represents the aperture size/speed of opening/closing. Is there a way to get what I need for my project?

Hi @Victeldo ,
The Gen3 only reports the position and velocity that you have found (it does represent the open/close state of the fingers, in %).
There is no way to obtain the data you are looking for. I even think the gripper itself does not report all of these values.
