Gimbal Design Options: Wire vs. Steering Linkage vs. Direct-Drive/On-Servo vs. Geared Drive

I want to cover why I have been designing gimbals with wire linkages, and discuss some of the potential advantages and disadvantages of some of the best alternate design options, and why I may start to adopt them. Wire Linkage: The main advantages of a a wire linkage are durability, flexible application, good performance, andContinue reading “Gimbal Design Options: Wire vs. Steering Linkage vs. Direct-Drive/On-Servo vs. Geared Drive”

Dual-Axis FPV Gimbal

I have finally tried building and flying a dual axis FPV gimbal, with camera pitch and roll being dynamically controlled via head tracking. I wanted to know if this would be possible to fly in acro, how difficult it would be to learn, and if it would be practical. I want to briefly discuss whatContinue reading “Dual-Axis FPV Gimbal”

On-Servo Design

I have started tinkering with a design where the top “hinge” rotates directly on the servos axle instead of having a secondary axle and linkage. This would provide some advantages if it were able to produce smooth movement but will also have some notable disadvantages, worth testing though. Will update post after initial testing. Update:Continue reading “On-Servo Design”

My Setup and Gear

The head tracker doesn’t add much to the overall system once it’s set up and working, I use the same carrying cases and bag. Your gear doesn’t need to match this to use a head tracking gimbal, the only thing you need is to verify that your transmitter supports a trainer function via an auxiliaryContinue reading “My Setup and Gear”

Early Designs

After some early testing I started to make some changes to the gimbal designs Andy Shin had made, reinforcing the hinge and even experimenting with designs that intentionally added friction to the hinge in addition to a sprung servo linkage in an attempt to stop the servo jitters from making it to the camera. IContinue reading “Early Designs”

Early Testing

Initial testing was more for the viability of a head tracking gimbal on a FPV drone than anything else, I had the idea several months back and after finishing some work on my home it was time to give it a shot and see if it would be flyable. For initial testing I used theContinue reading “Early Testing”
