I am making mobile robots for a while now, but the one thing which is still not changed in my journey is the use of those slow yellow colored BO Motors and their boring wheels. So, I wanted to change it and this is why I came up with the fastest, compact, inexpensive and 3D printed BO motors which I think is an amazing upgrade for my upcoming robots which will make my robots go faster.
