There's no mention of this here https://github.com/Kinovarobotics/kinova-ros

At the moment all I do is run the following

I home the arm using -

rosservice call /jacoarmdriver/in/home_arm

I then close the gripper (if it's open) using -

rosrun jacodemo gripworkout.py jaco 60 60 60

I then move the arm using -

rosrun jacodemo jointangle_workout.py jaco j1 j2 j3 j4 j5 j6

And then I try to open the gripper using -

rosrun jacodemo gripworkout.py jaco 0 0 0

but this time nothing happens. If I "home" the arm again and then try to open the gripper. It opens up.

Is there any solution on how to do open or close the gripper once it has moved after being "homed"?
