For robotics, I recently came across this course to learn the basics: https://github.com/henki-robotics/robotics_essentials_ros2. Haven't started it yet though.

Do this course https://github.com/henki-robotics/robotics_essentials_ros2 Totally free, don't need to buy anything just a computer. I've been designing electrical hardware for robots for the last 4 years for a big corporation and I can tell you, the fun and money is in the software but having another skill is awesome. Robotics is a place where multiple fields converge and if you find a good team they will help you to grow. Embedded is the adjacent field after you complete the course. Maybe something like zephyr project. If you want to get you feet wet with mechanical. Buy a A1 mini and play with onshape (www.onshape.com) to design your first pieces, supports for the motors or the board, try create you own gripper. As for the electrical engineering, is the one with most pitfalls and the most expensive. A wrong voltage will release the magi

cal smoke and is another 30$ for a board. Tread carefully. Start with the RP2040 or the RP2350, they are cheap and well documented. This skill will evolve hand by hand with the embedded coding. Start small. Learn about H-bridge and brushed motors before doing the jump to the bigboys and FOC control with brushless. Get a cheap soldering iron. If you can, a clone of the JBC C245 tips. Is the most versatile and you can find stuff in alie xpress for 45 or 50$ and would be similar to the tools you will find in the field without breaking the bank. Search for ROS meetups. I could point you to some depending where in the world you are. And above all, it will be a long journey. Don't dispear, do at your own time but don't forget the objective.
