Cameras, Gimbals, Mission Avionics


After several weeks of flight testing and tuning, I finally had a fully mission-capable end-to-end system, which included the UAV and both the Handheld Controller (i.e. RC controller integrated with handheld video) and a full blown Ground Control System.

It was time to start integrating the mission gimbals and cameras. The first of three camera/gimbal combinations was the GoPro with a direct drive brushless DC motor based Gimbal (using a SimpleBGC based gimbal controller).

To make it easy to swap camera/gimbal combinations in the field, I decided to dedicate a landing skip set (DJI calls them BiPods) to each camera/gimbal combination because BiPods can be swapped off the S800 with 90 seconds, with no tools required.

Also included are all the DC buses and video downlink subsystems (which vary from camera/gimbal combination to camera/gimbal combination).

The GoPro mount is the simpliest, although it still has two indepentend DC busses and a 5.8Ghz xmitter.

Heres the 1st BiPod, configured with the GoPro mount:
