I am new to UAV design and autopilot programming, but with some experience in quadcopter piloting. I am interested in breaking-into some autopilot programming. I am looking for suggestions for a quadcopter platform with multi-modality sensors (eg GPS, camera... ) where the information can be integrated into the autopilot algorithms. I'm not ready to build my own from scratch, so I was wondering if there is anything on the market that is close to 'ready-to-fly' but where I can get started with coding some autopilot functions. Price range, probably <1000 USD.
Additionally, if anyone knows about some good resources (tutorials, websites, getting-started on autopilot programming), I'd be very appreciative.
Thanks for the feedback and apologize for any mistakes in terminology.
