Exercise 2.1: stopping the robot

Course Support ROS Basics In 5 Days (Python)

I have completed ROS in five days exercise 2.1 but I can’t stop the robot from going around in circles. I was wondering what is the best way to stop the robot from continuously running the code.

Hello @mccannm,

You need to publish into the /cmd_vel topic a message with all the velocities set to 0. You can do this by using the rostopic pub command. It will be something like this:

rostopic pub /cmd_vel geometry_msgs/Twist "linear:
  x: 0.0
  y: 0.0
  z: 0.0
angular:
  x: 0.0
  y: 0.0
  z: 0.0"

Best,
