00:00 Introduction • 01:02 Review the design for the base_motor_controller and how I will support publishing Pose messages. • 01:46 Changes to the micropython code running on the Pico microcontroller to report back on how far the base has moved. • 03:40 Changes to the base_motor_controller ROS2 node to; receive movement info from the base, and publish Pose messages to ROS2. • 11:43 Short sidetrack to show the updates to the motor controller hardware (Moved breadboarded circuit to a PCB protoboard) I will use this for the demo. • 13:40 Demonstration showing ROS2 and motor hardware working together to accept Twist messages then report on the base movement using Plot messages. • 18:02 A look at the robot hardware I ordered to be used for my mobile robot base. (see https://www.dfrobot.com/product-1477.... ) • • Example of a Twist message: ros2 topic pub --once /base/cmd_vel geometry_msgs/msg/Twist '{linear: {x: 0.0, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.0}}' • Run the node: ros2 run ourbotmanager base_motor_controller • View Pose messages: ros2 topic echo /base/pose • Quanternion visualizer: https://quaternions.online/ • Lupincorp : https://www.lupincorp.com • ROS 1 for Beginners: https://www.udemy.com/course/ros-for-... • ROS 2 for Beginners: https://www.udemy.com/course/ros2-for... • Github ourBotManager_ros repository: https://github.com/somervda/ourbotman... • Github ourBoatManager_uController: https://github.com/somervda/ourBotMan...
