Hi,
I have connected to turtlebot in real robot lab and receiving live video feeds. When I try to move the robot with onscreen joy stick, it does not respond. When attempting to move the robot through terminal, by using teleop_twist_keyboard.py, it returns a msg saying Waiting for subscriber to connect to /cmd_vel. I have attached screenshot,
For the command rostopic list, it returns active topics (also in the screenshot).
How do I get the robot to respond to joystick commands?
I am using google chrome browser.
