Head Tracking Gimbals for FPV Multirotors

This sub-system significantly augments the filming capabilities and flight dynamics of a FPV drone and allows it to seamlessly transition from dynamic “proximity” flying into more traditional (non-FPV) drone shots, and vice versa, as well as a whole new set of maneuvers exclusive to this new sub-system. FPV pilots have gotten very good at flying and filming within the constraints of a fixed camera angle, but once you learn to use a head tracking gimbal, there is no going back, at least that has been my experience. I believe this is the next big paradigm shift in cinematic and freestyle FPV.

Exposition of HT Gimbal Capabilities and Dynamics

The technology isn’t new. In the early days of FPV people utilized gimbals, even ones controlled with head tracking, but the reality was that hobby drones flew so poorly at the time that it was best to have the flight camera fixed to the drone in order to achieve the best control. Times have changed, now FPV drones fly predictably, in addition we now have camera stabilization at our disposal. This opens back up the doors to increasing the capability of FPV drones.

To clarify, this sub-system isn’t confined to ‘angle mode’, I fly acro almost exclusively and the only exceptions are the same as I would have flying a traditional FPV drone.

Currently there is only one axis, pitch, that I have tested with head tracking, I also intend to try a two/three-axis design with a second servo controlling camera roll and possibly have the head tracker’s yaw being integrated into the existing yaw channel (since the yaw of a multirotor doesn’t affect flight path). This may be overly difficult to fly, but also may be the final step into ultimate control of a cinematic FPV drone…
