[!TIP]

The command format for viewing the data content, rate, and other information of other topics is the same; just replace the corresponding topic name

 

3.2 Controlling the Robot Chassis through Topics

  • Publish velocity commands to /cmd_vel to control the car movement:
xxxxxxxxxx
# Move forward at 0.3 m/s on the x-axis
ros2 topic pub /cmd_vel geometry_msgs/msg/Twist "{linear: {x: 0.3}, angular: {z: 0.0}}"

cmd_vel linear velocity publishing

xxxxxxxxxx
# Turn left in place at 1.0 rad/s
ros2 topic pub /cmd_vel geometry_msgs/msg/Twist "{angular: {z: 1.0}}"

cmd_vel angular velocity publishing

  • Stop the car movement
xxxxxxxxxx
ros2 topic pub /cmd_vel geometry_msgs/msg/Twist "{linear: {x: 0.0}, angular: {z: 0.0}}"

 

3.3 Controlling the Buzzer On/Off through Topics

xxxxxxxxxx
# Turn on the buzzer
ros2 topic pub /beep std_msgs/msg/UInt16 "{data: 1}" --once
# Turn off the buzzer
ros2 topic pub /beep std_msgs/msg/UInt16 "{data: 0}" --once
