I want to work on building a quadrotor or rover using Arduino/AVR. What is the best way to get started? Should I buy a kit with instructions? This is my first time venturing into robotics using microcontrollers. I am not sure if buying a kit is more useful (or maybe a specific kit produced by Arduino or Rasp Pi) as it may come with instruction or booklet to get started. This project would be a way for me to really incorporate system dynamics, physics and electronics engineering into practice. I would eventually like to use Simulink and incorporate it to control the robot.
