Just building my servo gimbal as instructed about. I have printed my gimbal parts and all works well. My question is this, it there any way of having the tilt adjustable? I want to replicate the gimbal stability with be ability to manually tilt the camera.

Hi Andy,

We would be very interested to see your custom Gimbal, you can post about it on our Forum.

As of now, i can’t find a way to make that happen on a ATmega 328 based board.
Still looking

Hi to manually adjust tilt, on the last image Multiwii -gimbal .I you slide the mid adjustment all the way to the right it then changes to give input ,ie Thr .Rud … aux1 these can be used to control the gimbal . I have not tried this on the MultiWii_2_3 – MPU6050 – Gimbal – 23-10-2014 program but it works on all the other multiwii 2.1-2.3

Hi, any multiwii board can work as a servo gimball controller, i have: Multiwii and Megapirate AIO Flight Controller w/FTDI (ATmega 2560) V2.0 board…and the software works with this board?

@CARLOS S
There are no special software involved here. The MultiWii project already have options for servo controlled Gimbal. The file, however, posted here are setup for that board specifically and might not work with your board. You will need to define your board in Config.h.

Salut Eric,
I am looking to control some ESCs as servo controllers. I have a multiwii, ESC, brushless motors but I want to use encoders for position feedback instead of an IMU.
Do you know if it is possible?
I tried following this:
http://www.multiwii.com/forum/viewtopic.php?f=7&t=2897&start=40 but it seems no conclusion was drawn for servo control with encoder…

thanks

Hi Jonathan,
Brushless gimbal use special drivers (ESC) and motors as it require a special KV winding to be able to make the motor move that slow with torque.
Using MultiWii might not be the best way since it’s not made for that purpose. You would have to modify the code for your specific application.

You might want to take a look at this post we found online:

Hello

Trying this project for my first time every doing anything like this. New to it ALL!

I purchased this board: https://www.robotshop.com/en/mwc-multiwii-flight-controller-uav-arduino-compatible.html#Useful Links

But I am not sure what to select on the drop down for board types, the one you show does not show up on my mac version of Arduino. I chose Arduino Mini but it did not work.

Any ideas? Also how do I know which Port to choose?

Hi Eric,
I’ve tried to test my 3d printed gimbal powering the board from an USB port and since them my multiwii board doesn’t work anymore. Neither the arduino IDE nor multiwii GUI is seen it anymore. Can you figured what could’ve happened ? What is your wild guess about the damage part ? The board itself or the FTDI ? The blue led are blinking wildly and at the FTDI side only the TX led blinks. Thank you and sorry my poor english.
