I have a Robotiq 85 2-finger gripper that I'm using with a UR5 running version 18.104.22.1686, and would like to control remotely (presumably via URScript).Perhaps I have missed something basic, but this does not seem to be working, and behaves in ways I would not expect.When I run "gripper_tutorial.urp" from the pendant, that does work. But when I single-step through any of the rq_* commands (using the >| button on the bottom of the pendant display), I get a compile error, e.g., "Compile error: name 'rq_close' is not defined". Likewise, sending rq_* commands over a socket does not work; there does not seem to be any effect.I can control the gripper remotely using raw socket commands from URScript, e.g., socket_set_var("POS", 255, "gripper_socket"). But that does not seem to work reliably, and does not seem like the right way to do things given the presence of the rq_* commands.Any idea what might cause this behavior? Have I missed some initialization step? Shouldn't I be able to send "rq_close()" (e.g.) over a URScript socket?
