I have seen several online courses related to Lego EV3 and this for me is one of the best. In his lessons he not only learns robotics, but also indirectly, logic, programming, physics, mathematics … in a pleasant and practical way. I am doing it with my 14 year old daughter, and we are enjoying and learning a lot. These lessons are very useful for parents who want to teach their children robotics (and take advantage of LEGO Ev3), students who want to self-form or robotics teachers who want to improve their level of knowledge. Thank you very much for your time and you always fast and precise answers to our doubts.
