Hey guys I am wanting to take my skills to the next level by making this crazy quadruped robot. Essentially, I am wanting to have head tracking fpv, gps, and for this robot to remote control. Additionally, the robot will use 4 brushless motors and tons of servos (for the legs). I also want to make my own pcb board which is where I get lost. Where do I start to learn microcontrollers and how to make my own?
