ros2 topic pub /hello std_msgs/msg/String "{data: 'Hello, robot!'}"

# In another terminal
ros2 topic echo /hello

Create a ROS2 node

Minimal Python node that prints every second.

import rclpy
from rclpy.node import Node

class HelloNode(Node):
    def __init__(self):
        super().__init__('hello_node')
        self.create_timer(1.0, self.tick)
    def tick(self):
        self.get_logger().info('hello')

rclpy.init()
rclpy.spin(HelloNode())

Robot velocity control

Send a Twist to /cmd_vel so the robot moves forward.

ros2 topic pub /cmd_vel geometry_msgs/msg/Twist \
  '{linear: {x: 0.2}, angular: {z: 0.0}}'
