Re: 2f85 ROS controller

Hi @jproberge,

Thanks for the reply. I actually found out the problem is on my side instead of the ROS Robotiq package. It's a simple mistake being that my 24V power supply was clipping the current it can output. After I increase the current limit everything works fine.

Re: 2f85 ROS controller

Hello @jleng !

Thanks for reaching out to us and I'll be happy to help you with that! I'm sure we will find a solution soon.

So just to be sure, you should first run this command :

"rosrun robotiq_2f_gripper_control Robotiq2FGripperRtuNode.py /dev/ttyUSB0"

without quotes, and assuming your Robotiq gripper was mounted as /dev/ttyUSB0. Then, this is when the gripper's led should switch from red to blue. Once that's done, you can try to use our simple minimalist interface to find out if everything if properly working. To do so, you just have to run:

"rosrun robotiq_2f_gripper_control Robotiq2FGripperSimpleController.py".

Then if I understood properly this is when there is nothing happening, am I right? If so, could you:

1) Try to first activate the gripper (pressing on the "a" key on your keyboard, then "Enter"). if that didn't work, reset the gripper ("r"), and re-activate it ("a" again). Try to see if you can now manage to open/close the gripper. I feel these simple steps should make it work.

2) If 1) didn't work, could you please tell me if there is any error message / warning of any kinds? Also, in that case could you please tell me what Linux OS you are using and ROS version. Also, one quick test to make sure this is a problem related to ROS and not a problem related to the gripper itself, you could try using the Robotiq User Interface (on Windows though) as a quick test.

Please do not hesitate to reach out to me if you still have issues or any other ROS-related question(s).

All the best,

Remote control of Universal Robots user interface

Hi. Has anyone tried to or does anyone know how to remote control Polyscope, the user interface of Universal robots?

I’ve had the idea to install VNC server on a robot to be able to remote control the user interface. And now I can see a company already is selling it as a part of a product:

https://blog.universal-robots.com/industry-40-is-here

Does anyone know how to install VNC server on a UR robot?

Maybe it’s possible to install and set up VNC server using a magic script?

I know that by attaching a USB keyboard and by pressing <ctrl>+<alt>+<F2> you’ll switch interface to the Linux console. Maybe it’s possible to install VNC through this console? (pw: easybot) (Press <ctrl>+<alt>+<F7> to switch back to Polyscope.)

By installing VNC server it would be possible to remote control and troubleshoot a robot from office PC, tablet or smart phone... It could be quite useful.

Re: Hand -E gripper

Hi @tom24,

The default password to configure the maximum force and speed of your gripper is "rqsafe". It is meant to block certain users from exceeding this limit and not to configure your gripper movements. Your gripper should be able to get detected using the Scan button of the gripper Dashboard. It can either be activated from there or from the UR+ toolbar if Show gripper toolbar option is checked. The force and speed of your gripper can always be changed from the UR+ toolbar or a gripper node while coding.

Hope this helps you get started with your gripper.
