The init method always takes two arguments: ![]() ), is actually the ROS node counterpart of the Python _init_(self. setVelocity ( command_motor_right )Īs you can see, the MyRobotDriver class implements three methods. z command_motor_left = ( forward_speed - angular_speed * HALF_DISTANCE_BETWEEN_WHEELS ) / WHEEL_RADIUS command_motor_right = ( forward_speed + angular_speed * HALF_DISTANCE_BETWEEN_WHEELS ) / WHEEL_RADIUS self. _node, timeout_sec = 0 ) forward_speed = self. _target_twist = twist def step ( self ): rclpy. _cmd_vel_callback, 1 ) def _cmd_vel_callback ( self, twist ): self. create_subscription ( Twist, 'cmd_vel', self.

It is recommended to understand basic ROS principles covered in the beginner Tutorials. They are documented in the Webots ROS 2 examples page. Some other sub-packages contain demos with different robots such as the TurtleBot3. It includes several sub-packages, but in this tutorial, you are going to use only the webots_ros2_driver sub-package to implement a Python or C++ plugin controlling a simulated robot. The webots_ros2 package provides an interface between ROS 2 and Webots. In this tutorial, you are going to use the Webots robot simulator to set-up and run a very simple ROS 2 simulation scenario.
