2024.08.26 Hi did you connect the gripper to the control box or labtop??? Which one does the gripper use, 2f-140.2f-85? I use a 2f-140 gripper.
First, find robotiq_2f_140_macro.urdf.xacro. Second, find "com_port:=/dev/ttyUSB0">" It'll be in the 15th row.
If you connected with labtop, use ttyUSB. But if you're connected to the control box, try using ttyS.
I wrote the following while I was connected to the control box. It was connected.
Thank you.
2024.08.27 It was confirmed that ttyS is not working. Use ttyUSB.
Hi @Mokchanic
The 2f-85 gripper was connected through USB to a computer. Before I figured out to set the com_port
field in the xacro, I was stumped by the error message mentioned above. There should be a better message to indicate gripper connection is not detected.
Hi @Abishalini Does the computer not detect the port connection or is it designated ttyUSB0? Check out udevadm.
sudo udevadm monitor
Find your ttyUSB number while connecting or removing the port.
By the way, are you using 'ros humble'? Did you run the .repos file?
During bringup, the RobotiqGripperHardwareInterface throws the following error if the gripper is not connected. We need to get a better error message about the failure to connect to the gripper.
