VR GIMBAL ( Board Control and IMU ): We are ready for developer.

[Roberto Navoni]

 

 

Dear Friends,

after one week of work to first sample of electronics , we are ready with workspace enviroment for developer that want join our team.

Electronic Specification: 

In VR Gimbal We decide to use this kind of electronic parts  :

• as micro we use STM32F1 64 pin.
• 1 MPU6000 + HMC5883 for Z axis Direct Drive CAM using i2c bus.
• 1 MPU6000 on spi bus. for Roll and Pitch cam.
• EEPROM for storage the parameter of gimbal.
• 3 ST Driver for manage 3 Brushless Motors with 9 Hardware PWM Output.
• 1 input for Ublox GPS.
• 4 PPM Radio Input or 1 PPMSUM radio input until 8 channel or more.
• 1 Telemetry port for mavlink control.

 

As developer enviroment we use VR Ide Universal (based on eclipse) compatible with VRBRAIN and MP32 board now also with VR GIMBAL.

The developer lib and hal at the begin will be compatible with our APM_LIB ported to STM32F1 library the same used on MP32F1 board. 

That support all the APM library available and arduino language sintax .

 

In our code we decide to port on VR Gimbal :

• AP_COMMON
• AP_VAR
• AP_InertialSensor
• AP_IMU
• AP_Camera
• AP_Mount
• Mavlink

 

and other utility yet available on our standard F1 package ... 

 

We would develop also a utility for manage the board from 

 

 

If you are interest to join our work in developing stage will be a special price for you of 75 euro of 3 axis control board + 15 euro for IMU  (at the moment is available only 20 board) .

 

You name will be in the list of developer of this great project. The code will be opensource as other in this great community ... the support in development and donation are welcome .

For more info about the project contact me at [e-mail]

In our roadmap the first  stable version of code will be available in 1 month. 

In the next week will be available the enviroment , with hal and library , then starting to implement the code functionality for manage the first opensource 32 bit 3 axis direct drive.

I hope that you like our project and join us in development.

In VR Lab mecatronix group are working hard and is yet available a good gimbal for GOPRO

 

 

 

 

And also is coming Gimbal for pro and semi pro camera.

I hope that you like our work :)

So the reaction speed is still a lot faster than any disturbance that the model can throw at it.  Which brings me to the next point. Most people are putting the pan axis on the first motion arm however I have a better solution and that is to put it below the camera base plate. This allows the camera to be used in the portrait orientation and be able to tilt downwards. Providing that the software allows the roll axis to move beyond 90 deg. (most publications are portrait format so for photography work this is a big plus.

Although the attraction of the brushless concept is that it is direct drive, I have been working on an indirect drive system which has the following advantages. It has a lot more torque and holding power plus it is far less sensitive to any external force that can knock it out os sync.

Hi Denny,

we support all te i2c component available on the market

[Denny Rowland]

The 9150 comes with the same gyro and acc. features plus the AK*975 three axis digital compass and the built in motion fusion algorithm. Surely this must be the way to  go?

[Denny Rowland]

Roberto when you say 9150 in respect of 6050 with 5883 have less precision which one are you referring to that has less?

Today i open a VRGimbal repository this is the link :

tks for the info :-)

today the work on AP_Inertial_sensor and AP_Compass it's ok all work fine.

Also AP_AHRS work ... tomorrow check the data from AHRS and start to doing first integration with motors.

Hi Paul,

9150 still available but respect of 6050 with hmc5883 have less precision.

Hi Roberto,

the 27 of April you wrote: "

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."

Now i see only the MPU 6050 option and no more 9150. Am i right or i missed something..?

Thank you for your reply.

Paolo.
