It probably wouldn't be to bad for an entry level project, but depending how much you wanted to do from "scratch" it could get very complex very quickly.Is something like this what your are thinking? https://www.youtube.com/watch?v=16wCUMcpOZEYou might want to check out gimbals for quad copters as that might be a good starting point.
Here come the price, there is expensive gimbals but as well cheap, you can make them on your own or buy them ready. Using servo motors is a good starting point but you still will get a bit of shake for bettersmooth quality you need brushless motors but as well the price is big. If you want to build you own one start small don't spend hundreds just few dollars get some 9gr servos, mpu6050, arduino and use PID formula to balance them. Don't be scared ofthe programming it's really easy after you take few hours of look. Think about those points, start small, prototype, understand and then go big.D.60
Thanks for the responses its helps to know theres a practical application possible eventually.
