Gripper Joystick Controller

[jorgegalds_DON]

Hello everyone,

 

So I was trying to test the Gripper Joystick Controller found at the Intera Examples. I have a PS3 controller and have successfully paired it to my ROS using the ps3/Joy tutorial. But when I follow the Intera tutorial on how to run the program, I am always facing the error "IndexError: tuple index out of range". I know it is not the same nut I tried the Gripper Keyboard example and that one worked perfectly on my Sawyer.

If someone has experience running this example I would greatly appreciate the advice. I might also text it using an Xbox 360 controller but I think it should be working as it is because the connection is stable with the PS3 one.

 

Thanks in advance for any advice.

 

-Jorge
