Radical M carbon gimbal

Hi,

I would like to announce my newest project which was made during last few months.

Weight for 2 axis 520g

Weight for 3 axis 620g

Alex or other controller

All wires and pcb inside the frame

Camera size - Sony Nex or similar

Project sketch:

The drawings I've made in Rhinoceros; very simple and useful tool. After watching few tutorials I was able to draw this project.

Prototype, the surface not finished yet.

Controller is located inside Roll frame on the middle.
And first production 2 and 3 axis.

Nice design, I like it.

Very nice looking. How well does it work? I've been struggling for a long time trying to get any open-source DIY gimbal working properly.

Superb!

One axis - one motor?

Rob,

basically I'm satisfied with the gimbal. Is very light and most important thing is stiffness. The test gimbals has Alex 32 bits with typical IMU sensor. I think the next step is consider to use encoder. In this case we will not loose any step and environment temperature changing will have no influence for gimbal behaviour..

Lazy,

one axis one motor. In case of roll, on one side we have motor and in to opposite IMU sensor.

Enought power? What motors you are used on each axes?

Pitch GB 2808

Roll GB 4006

Yaw GB 4008 or 5208 with slip ring

Its enough power.

awesome looking design, even the commercial ones are dust against it.

How did you manage to work with carbon for a personal project?  

Doesn't that need industrial machinery(extreme heat) and specialized handling skills?

I am afraid to work with even fibre glass on CNC. Was happy with wood and plastic till now. But looking at that all my prusa and shapeoko worked items seem like trashcan stuff :-(
