Gimbal Control- The Principle And Application


Electronic camera stabilizing gimbals have emerged with a boom. The very first 2-axis gimbals were servo-controlled as well as placed on multi-rotors to stabilize the video clip or FPV (First Person Sight) cam. Ever since the modern technology has actually advanced substantially as well as brushless gimbal motors are a common view on the marketplace. The whole point of a gimbal is to maintain a payload secure and in the exact same orientation independent of what its mounting system is doing.

That was a handheld brushless video camera stabilization rig, I am developing a 3-axis brushless gimbal that is going to be installed on a multi-rotor, most probably a quadcopter this contact form.

The concept behind the entire thesis is that it can be made use of for SAR (Browse as well as Rescue) objectives. As a member of a SAR celebration, you desire an unhampered sight of your bordering atmosphere, yet an extra pair of eyes overhead might be extremely useful also. Google Glass is among the few readily available HUD (Head Up Display) platforms that provides you the capacity to check out a HUD display whilst still having an unblocked view of your surrounding. The display does not need to be huge if the camera payload is a infrared camera that seeks a person's warmth trademark, something like that would certainly be easily recognizable on the Google Glass' display.

The suggestion is to have a quadcopter that is flying above you, and also you can manage the gimbal merely by moving your head around. Furthermore a placement lock function would be very valuable. Now this is no simple task, but it is something I would love to include in the whole system. The control algorithm will be based on a trigonometric mathematical design of the orientation of the gimbal, the heading of the quadcopter and the direction in which the gimbal is dealing with. Every one of this info will be provided by a GPS, Pressure sensor and compass, and also the base controller will be a Arduino Mega 2560.

When a position lock is activated, the gimbal ought to deal with the video camera lens so that the general location listed below the quadcopter remains in view, in spite of the activities of the quadcopter. Normally the head motions of the controller will have no effective input to the system in this state. The controller after that has a visible picture of a certain location without having to preserve head control over the gimbal.

Feiyu Tech G4-QD Quick Dismantling 3-axis GoPro Gimbal


The Feiyu Technology G4-Quick Dismantling 3-axis Gimbal for GoPro is an updated version of the Feiyu Tech G4. The biggest distinction is the method the electronic camera is held.

Feiyu G4-QD uses the conventional screw mount while the Feiyu G4 QD utilizes a brand-new created flexible springtime mount. You can utilize this Gimbal for Yi and also GoPro cams.

Two batteries are required to run the Feiyu Technology G4-QD but 4 batteries are consisted of with the cam so you can bill a collection while the various other set remains in usage.

The power switch is located at the end of the gimbal so there is no choice to make use of a tripod. There is an optional extender tube that can be contributed to the bottom of the gimbal.

You will require to activate the gimbal prior to you attach the extender tube as the power button would certainly not be offered.


Panning Setting:

The power button lies at the end of the gimbal so there is no option to make use of a tripod. There is an optional extender tube that can be added to all-time low of the gimbal.

You will certainly require to switch on the gimbal before you attach the extender tube as the power button would not be readily available.


Panning Setting:

Video camera is allowed to pan left or best. Upright turns or rolls are restricted

Panning/Tilting Setting:

Cam is permitted to pan left or right as well as turn up and down. Rolls are limited

Full-Axis-Lock Setting:

Electronic camera remains in its existing alignment. All panning, turning as well as rolls are restricted.

Upside down Mode:

Enables you to turn the gimbal positioning inverted and also shoot in angles that was when thought difficult.


Easy to make use of out of the box

Automatic calibration

Suitable with optional remote control


Challenging to place electronic camera making use of spring mount

Incapable to adjust roll without the optional remote control

Need to power on gimbal before affixing optional extender tube


The Feiyu Technology G4-GD one button control make it very easy to utilize yet does not have features of being able to change tilt, pan or roll without acquiring the optional push-button control. My recommendation is to obtain a portable stabilizer gimbal that you can regulate tilt, frying pan as well as roll on the fly.

EVO GP 3-Axis GoPro Handheld Gimbal


The EVO General Practitioner 3-axis GoPro Handheld Gimbal is the very best total gimbal for GoPro on the marketplace.

Capturing pro-quality, motion picture like video with your Hero3, Hero3+ or Hero4 Electronic camera is very easy.

Allowing for stable shots in extreme situations.

The stablizing motors are additionally solid sufficient to attach different GoPro accessories such as the Battery Knapsack and the HDMI cable for an external point of view.
