When I launch
roslaunch summit_xl_gazebo keyboard_teleop.launch
i have this error:
SyntaxError: Missing parentheses in call to ‘print’. Did you mean print(msg)?

what it means?
I think it should start whitout launching/running anything before launching keyboard_teleop.launch.
Thanks in advance,
Stefano

Hello @Stefano ,

That command is wrong, you need to use the teleop program for the Husky robot (which is the robot used in the Exam). The command is:

roslaunch husky_launch keyboard_teleop.launch

Best,

In the exam I’m using the Summit robot. The name of the page is: “Navigate the Summit XL Robot Autonomously in an Indoor Environment”

Hello @Stefano ,

Oh, you mean the Project of the course. Ok, I’ve already fixed this issue, you should be able to launch the teleop program now. Please change to another Unit and come back to the Project to make sure that you get the latest changes I’ve made.

Best,
