Camera stabilizer 3 axis brushless motor controller systems: EvvGS and UStab with 3-STAB firmware
Getting smooth handheld aerial videos and pictures is quite challenging. There are many stabilization systems, but the most cutting-edge solution is a brushless gimbal. This solution is universal and allows you to use the camera gimbal as a handheld steadicam, as well as the camera binding for the flying drone or any other mobile system with more than 1 degree of freedom.
Our project is the further development of the open source project EvvGC – a controller that manages brushless engines stabilizing the camera position, and is the core part of the whole gimbal system. We haven’t changed the open architecture of the controller, but we have completely rebuilt the managing algorithms after months of designing and testing.
As a result, we’ve created an almost universal solution for getting impressively smooth videos for cameras of all classes. Our 3Stab firmware for EvvGC is compatible with our new UStab controller based on STM32 processor too. Currently, our team is testing the new architecture that we’ve built ourselves. In this new upgraded architecture we’ve fixed all the bugs of the EvvGC controller and have significantly increased the power of the managing channels (up to 8A per engine), which allows using it for almost all heavy cameras.
This video was shot using the Panasonic GH2 mirrorless camera with the 3 axis gimbal for video stabilization on the bases of the EvvGC controller and 3-STAB firmware. As you can see, it’s possible to get a stabilized video without any post-processing even in the complicated shooting conditions, including the high level of vibration and acceleration. So the greatest thing is that no matter what your operator’s skills and how nasty the weather is, this solution will help always get a professional video.
