ATM I'm planning a quadrocopter, a flying robot. For the first steps into this project I want to make it float in a certain height. So I'm going to order the motors and so on, and now, here's the question concerning the sensors. First, the robot will only get gyroscopes and accelerometers. So, if you ask google, you'll get many different parts, some combined, some not. I would like to ask you; what are your experiences? Which would you recommend?
