Gripper connected to control box not connected #1109

Open Mokchanic opened 1 month ago

Mokchanic commented 1 month ago

Affected ROS2 Driver version(s)

humble

Used ROS distribution.

Humble

Which combination of platform is the ROS driver running on.

Docker

How is the UR ROS2 Driver installed.

Build both the ROS driver and UR Client Library from source

Which robot platform is the driver connected to.

UR CB3 robot

Robot SW / URSim version(s)

URSoftware 3.14

How is the ROS driver used.

Through the robot teach pendant using External Control URCap

Issue details

Summary

Gripper connected to control box not connected.

Issue details

Gripper is recognized when directly connected to the computer, but not in the control box. I referred to the link below, but it doesn't seem to work in cb3 because it's e-series only.

Yes, this does not work.

Yes, this does not work.

thanks! I met the same problem and I now find out that 'use_tool_communication' is not for cb3 robots. if so, is there any method to control a robotiq gripper using ROS2 and Moveit?

I find 3 different ways to control robotiq gripper in https://sdurobotics.gitlab.io/ur_rtde/guides/guides.html#use-with-robotiq-gripper Option 3 proved available in python
