You may be asking your self, "Self why have things been so quite over at the TRIAX|AERIAL camp recently?" Well its because we have been hard at work filling many orders in addition to developing TRIAX|CSM or TRIAX|Camera Stabilization Module.

TRIAX|CSM is a small single unit designed to stabilize tilt and roll axis for camera gimbals with the future addition of panlock for the pan axis.

TRIAX|CSM is still currently in early development however I wanted to take this time to give a sneak peak to the community as well as inform you that we expect it to only be a few months until the unit is ready for sales. In addition if you have any questions, or suggestions for features you'd like to see incorporated we are all ears.

Here are some specs:
-Currently the TRIAX|CSM is designed to work with the TRIAX|lite line of camera gimbals.
-TRIAX|CSM is a small single module that is placed below the camera on the gimbal, because of this TRIAX|CSM will work with non-TRIAX|AERIAL mounts(further testing planned in the future).
-Currently have 2 axis tilt and roll working in our early development board with the addition of panlock in the future.
-Drift free, on initialization TRIAX|CSM creates a virtual horizon and will not drift from it.
-Works with continuos rotation servos.
-In the case with mounts that use coreless servos TRIAX|CSM will keep the servos from free wheeling from the weight of the camera.

More information to come soon.

Below you will find some of our early development tests. At this stage shown in these videos we have about 6 hours of development time in the software. Results are very good yet we still have a little ways to go. You will notices that in these early tests response time is about a half second slow, but over all TRIAX|CSM in this early form is working very well and would be acceptable for most cases.

Please note the following videos are of early alpha software and does not imply final production results. Final results will be better. Also note that these videos are raw straight out of the camera, no post processing done.

Video 1, Mirror test:
This is to show how in its early stages the TRIAX|CSM corrects for unwanted movement in the gimbal keeping the camera stable.

Video 2, Drive test:
This was to test the TRIAX|CSM under similar conditions found when used on a RC helicopter. Driven on a hard bumpy vibration ridden gravel road yielded no unexpected results.

At this point we really need more then 6 hours of software development time. Progress is moving quick though.

Derek....do you have an ETA for your mount being available for the Maxi-Joker 3? Thanks..

I wanted to take a quick moment to post an update on the status of TRIAX|CSM.

We are nearing completion and are in the stages of further testing. What has changed since my first post? Reaction time on roll and tilt sped up. Added Pan lock feature.

Here is a sample in house test. I will be posting flight tests in the coming days.

Remember the 3 axis stabilization is a single unit mounted under the camera. No need to remotely mount IMU boards for each axis. One unit controls and stabilizes all the axis.

Adding the Pan axis is a nice improvement/feature.
It is something that many people are continuously asking me for !!

Derek, can you post a video clip showing the camera tilt axis pointing 45 degrees down or up, to show us that with your IMU fixed to the camera axis (center of gimbal), there will be no cross coupling of the axis's movements or controls, when they are not aligned ??

Thanks, and keep it up !!

Yes i will see about getting a video of that tested. That shouldn't be a issue though because we use a single unit with all the sensors self aware of each other. The issue could come in if you were to go 90 degrees off axis, then the sensors need to swap what is axis are being controlled.

Nice gimbal, but IMU needs improvement. In one of the videos roll lost the level.. I hope you resolved rotation projected on non-orthogonal axises.. Can you test this: disable pan gyro, give 45 degrees tilt, and do a fast pano.. If roll and tilt stays levels, than its ok..

Hi Derek,
This is what we need. Your CSM appears to be in control most of the time. It is unusual to have your stabilization work with continious rotation servos.
What kind of servo?
No feed back?
Do rotation axiss have limits or stops?
"Park" or "Home" position?
I am looking forward to this coming on the market.

>>"we use a single unit with all the sensors self aware of each other"

Yes.. of course!! .. they're mounted orthogonally to each other. They have a fixed relationship.

But when you slew one or two of your axis ( as in normal camera shooting), the actuators (or their axis) are not orthogonal anymore, and you get cross talk between the sensors and your beautiful gimbal. This might lead to uncontrolability, especially if turned 180 degree out of phase to the actuators !!

That is one of the reasons why with PicLoc-TR, I went with seperate units for each axis, so that "each department" takes care of his "space" only.

Your system will work.. only if you provide sensors that "know" what position is the gimbal carrying them, so that you can transpose the commands to the servos. And that will just add to your hardware and component cost

Good Luck... !!

GeorgeM

PS.. any Idea of price for CSM ??

@denizcan .. nice work on your unit!

I am processing the 45 degree video test now and will upload it shortly.


denizcan: if you read the first post i made i explained that responce time on the roll axis was slow because at that point we had only 6 hours of coding and development time into TRIAX|CSM and that we needed more time with the code and our hardware. The latest video i posted yesterday has considerable more time put into development with many new features added.


Helicek: TRIAX|CSM works with modified 360 continuous rotation servos with the potentiometers disabled. The system basically creates virtual potentiometers to track the servos movement.


eyeinsky: Thanks!

GeorgeM: We have an idea for price in mind but are not ready to disclose at this point. Our unit works a little bit different then yours do and we have spent considerable time testing and developing the hardware and software and so far we are very happy with the results.

@ Derek - Fair enough.
Point Taken.

Re: the 45 degree video.. can you leave the sound of the servos on ??
