VR GIMBAL : 3 Axis 32bit Direct Drive Gimbal is coming!

This is main board normally put on Gimbal frame near the Quad .

This is the two options imu available normally is on camera module:

2 axis with 3 accelerometer and 3 gyroscope 3 magnetometer in one version we use mpu6050 and in other we use mpu 9150 1 chip 9 DOF sensor.

Some friends start to design different kind of gimbal for our new board. The main difference respect of standard gimbal is that the mechanical frame need to be develop for each video sensor that you would like to use for your video. This frame is for Gopro Hero 2-3 in the design is important to move CG of camera for obtain better result during gimbal stabilization :)

This is the caratheristics of our : VR Gimbal :

Micro Controller is STM32F1 at 72 mhz.

3 Axis Brushless Direct Drive gimbal :

Roll (MOT1)
Pitch (MOT2)
Yaw (MOT3)

For each channel we have 3 high power pwm output .

I2C IMU that support 3 axis . It is on camera module , so we can know exactly the position of camera and control in realtime the 3 Brushless motors.

We are developing two option :

more traditional approach : MPU6050 (6 DOF) + HMC5883 (3 DOF)
new sensor from inversense MPU 9150 (9 DOF)

1 USB port.

1 Serial port that support mavlink protocol.

1 Power module that support until 3S battery.

4 Radio RC Input for :

Control ROLL Setup.
Control Pitch Setup.
Control YAW Setup.
IR control repeater.

4 Analog Input 0-3.3v

1 IR Out , so is pssible to control a remote camera by its ir receiver.

The first batch of production will be available in 3 week it's better to reserve your board because there is a big request of this gimbal.

John, yes BLGC motors are totally different from normal BL motors. Most of them are wound different way, size of copper is different also amount of winding turns is different. Normal BL motors are 700 to 1200Kv for multicopter use but for BLGC use we try to as close as possible of 0kv. Ok 0kv is impossible to achieve but something like 5-50kv is not.Not all motors are suitable for this. Many of them have problems when winding big amount of cable to them. From motors available on market in generally only small amount makes good BLGC motor.We worked with many motor companies in past and its great that now many of them are making those as hand windig is really painfull... it can take up to 3-4 days to wind one motor by hand :)

Thanks for the info Jani, yes I can see now how that makes sense.

By the way when are your BGM gimbal frames going to be available? Also do you sell any cables with a DF13 connectors? I'm looking for one to connect my external magnetometer to my APM2.5. I couldn't find any on your webs site.

Are the brushless gimbal motors in the market wound any differently to the regular brush less motors? eg can we use the same brushless motors we use for a quad copter on a gimbal?

Hi Jani ,

i invest for doing an original product copy what is yet available on the market is , too simple :) AleX doinga great work ... but with our experience we can do better :) Why put a limit in our fantasy ;) The main work doing STM32 is to do a motor controller why use an old atmega328 ... is anachronistic :)

OG there will be 3 axis coming from jDrones too and electronic is created together with Alexmos. I think many other Alexmos suppliers will have it too soon. Germanese copy of Alexmos made by Martinez (same what is made widely in China) won't have it as they are using different software and you cannot run Alexmos software on those boards.

Yes, I agree on you.

VR Gimbal control board is nicely made. And I found strong ARM processor is sitting in the middle of the board.

Hi jiro ,

APM 2.x is not good as gimbal because you need to have on board a 3 channel driver for control brushless motors ... this is the first picture of VR Gimbal ( Control Board)
