Introduction: Motorized Panorama and Timelapse Pan Tilt Sytem

This is my second motorized panorama and timelapse pan tilt system.
This one is more portable, power saving and effective.


Two 1:50 harmonic geared stepper motors are adopted as the key driving
mechanism. Owing to the low backlash of the harmonic gear drive, the wobble
caused by the wind has been reduced greatly. And it got significant effect
on the timelapse video.


An Arduino nano and three A4988 are being used as the controller.
Simple and small. Much better than the Mega 2560 and L298 ever used in my
last system.

Step 1: Pan Tilt Tripod Head

This pan tilt tripod head consists of two 1:50 harmonic geared stepper motors,

three camera quick release adapters and some aluminum bars.

No additional gear, bearing, timing belt or else are required.

It makes the fabrication works very simple.

Precise workmanship is not required basically.

A bench drill and some fitter's tools will be OK.

Of course, a bench milling machine will help a lot.


The dimension of the tripod head is counting on your camera and lens.

My tripod head is strong enough to handle a full frame camera and a 400mm F5.6 lens.


As an advice, before go into the detail of your own design,

make sure that you understand the concept of "nodal point" for panorama.

Step 2: Controller

The two steppers are controlled by an Arduino nano and two A4988.

An additional A4988 is spared for the slider.

And the camera shutter is controlled by a small reel relay.

Step 3: Functions

This system gets four major functions for the timelapse and panorama.

Step 4: Program

In order to control the steppers and camera shutter precisely, no stepper

library is used. And to minimize the wobbling, acceleration and

deceleration have also been included in the program.

The first program is to set up the default values in the eeprom.

And the second program is the main program.

Step 5: Results

Some timelapse clips and a 880 million pixels panorama photo have been taken.

And it is the time for further field testing.

Just put everything in a backpack, and ready to a day trip for photo taking.

Alibaba is fine. New harmonic reduction gear is very expensive, u can consider planetary reduction gear.

Hello and congratulations for this superb achievement.
Would it be possible to have a list of the necessary equipment and a little more information on the realization not only of the electronic part but also of the mechanical panoramic head engine link etc...
Thanks in advance

yo primero he hecho la simulación con el proteus y ahora estoy empezando el montaje. Si te puedo ayudar en algo me lo dices.
Saludos... Jose

For the electronic parts, pls refer to the circuitry diagram.
For the mechanical parts, other than the 2 motors and quick release plates, all are DIYed.
I used two NEMA 17 steppers. And two 1:50 harmonic gear drives for the steppers. Second hand stuffs, not easy to purchase. Can consider to any other steppers with reduction gears.

hank you for your answers.
In fact even the connecting rings between the motors and the parts of the ball joint you machined them.
It's really good work. I have recovered stepper motors but I don't think they will suit.

Hello,

I continue to discover the project in depth and I just saw that there are 2 stepper motors and 3 4988 circuits. What is the third circuit for?

Thank you

It is for the third stepper of a slider.

Ok
Thank you

In the coming months, i will try to carry out this project which is great, but i'm new to arduino, so it may not be easy.
The more I look at your creation the more questions I ask myself. For example I counted 12 buttons. I think I see 8 push buttons on the front as well as a slide switch. Then 3 other slide switches on the front side. I suppose the rear sockets are the engine card links and the power supply.

To simplify the electronic works, you can consider to use a GRBL CNC controller directly. Like this one https://www.amazon.com/HiLetgo-Printer-Stepper-Eng...
On the left hand side, there is a hole for the USB cable (for sketch download), and a socket for the battery power supply.

I just ordered this model on aliexpress, as well as a support with screw outlet for the nano.

Hello, I am doing the project, waiting for the planetary gearboxes to arrive.
I'm testing the Proteus and everything seems to be going well. But when I put it into practice, the engine accelerates a lot. Is it a hardware or software problem?
Thank you.

Sorry, get no clue. This program is too old, can't recall the detail. As long as I remember, the acceleration calculation is depended on the machine design. May be retest it after the planetary gearboxes are arrived.

I made it . But I did not find the mode with H and V timelapse together . Can you help me

Hi Amar,
There is no timelapse mode with both pan and tilt together in this instructables.
I do have new program for this timelapse mode. See below video clip.
But the program size is just too big, so only one timelapse mode can be put in the Arduino nano. May be another instructables some other days :)

Maybe on arduino uno or mega will enough . I will be waiting for code . . Thanks a lot for your job and time . And I print some part but did not finish it yet

Hi, I hope you'll answer this;
I'm trying to do the same thing, but I'm having a really hard time finding the geard box where I live. Do you know of a stpper motor that has enough torque so as to hold the camera?
Thanks! And great project BTW
