Some of the ROS courses I have purchased on Udemy.

Some of the lecturers on Udemy are excellent as they run through the workflows and conventions typically used for building and coding robots.

The offical online tutorials for ROS 2 are good, but they do not include an overall project outline.

GoBilda wheels work perfectly with Robotis Dynamixel MX64 actuators.

The first hardware for robotics that I acquired was a robotic arm with Robotis Dynamixel AX-12A actuators back in 2015.

A test robotic arm.

This has 5 Robotis Dynamixel MX64 actuators.

It uses MakerBeam and Dynamixel brackets for the structure.

I have coded a URDF model for use in Gazebo and have used MoveIt to control the motion of the arm.

The design is improvised with parts on hand.

Here is a test differential drive robot.

The actuators are Robotis Dynamixel MX64.

One of my test robots.

ROS 2 is difficult to learn, and the only way to master it is to tinker with actual robots, code in Python and C++, and test how it works.

I have completed some great courses on Udemy where the lecturer runs through the full process of building and coding a robot with ROS 2.

One of my test robots. This is a rover with 8 Robotis Dynamixel MX64 actuators. The design is my own.

The software used is ROS 2 (jazzy) on Ubuntu 24.04 with a typical ROS 2 setup.
