ErwinM5 Question 1 year ago.I was fortunate enough to get access to a prototype of Pi-Pan from www. The kickstarter has finished and they reached their goal. Pi-Pan can pan degrees from left to right and tilt degrees top to bottom. Pi-Pan comes with two servos, a controller board, screws, a mount and instructions. It also comes with some python code that shows how the device can be operated. The controller board in the image below is a prototype and the production board will be a lot smaller.

Pi-pan is well made and and feels solid once assembled, which only takes 5 minutes. There is also a mount which can be used to mount Pi-Pan on a case or other objects. I mounted mine directly on the Pi-Pan controller board for now. PWM is required to drive the servos and the sample code uses Servoblaster which works very well. I also used Servoblaster in my code below.

OpenElectronics also has a light module Pi-Light which can be mounted on the front of the Pi camera to improve lighting and there is also a case in the works.

In my previous blogs I shared, how to get started with Arduino and Servos. In this article we will see how to control a pan-tilt mechanism using servos and a joystick module. For this project we will need a microcontroller, I will be using Arduino UNO but any version will work. Two servos and a joystick module.

I have used joysticks salvaged from old PS controller but you can buy a module for pretty cheap. Also we need a pan-tilt mechanism, its easy to build one or even 3D print but I bought a readymade one online.

So to list it downhere are the things we need:. The assembly process is very straight forward, and most mechanisms will come with an instruction manual. Here is how the kit looks like:. If you want a detailed instructions on how to assemble the kit, you can check out this tutorial.

Before making the connections and uploading a code, we need to understand how a joystick module works. Below is an image of common Joystick module available for Arduino and Raspberry Pi projects:. We will be using all of these pins except Sel, it is a switch which shorts to ground when the joystick is pressed down. Most joystick modules should look similar. The one I used is salvaged from old PlayStation controller. Here is how it looks, if you want to use same:.

The unlabelled pins belongs to switches which are not required for this project. Both Joysticks work in a similar way, there are two 10k potentiometers one for X-axis and other for Y-axis. Moving the joystick around generates different PWM values which are sent to Arduino to control Servos.

As per the diagram, connect the vcc of both servos to 5v on Arduino. Connect Gnd of both servos to Gnd of arduino. The signal wires of one servo connects to pin 3 and other to pin 5 which are PWM enabled pins. The signal wires i. After the connections, final part is programming the Arduino. For that, open the Arduino IDE and write the following code:.A pan—tilt—zoom camera PTZ camera is a camera that is capable of remote directional and zoom control.

In television productionPTZ controls are used with professional video cameras in television studiossporting events, and other spaces. They are commonly referred to as robosan abbreviation of robotic camera. These systems can be remotely controlled by automation systems. The PTZ controls are generally sold separately without the cameras, but can also be sold as a set, as in the case of Fletcher cameras.

PTZ is an abbreviation for pantilt and zoom and reflects the movement options of the camera. Other types of cameras are ePTZ or virtual pan-tilt-zoom VPTZ where a high-resolution camera digitally zooms and pans into portions of the image, with no physical camera movement. Ultra-low bandwidth surveillance streaming technologies use VPTZ to stream user-defined areas in higher quality without increasing overall bandwidth usage. Surveillance cameras of this type are often connected to a digital video recorder which records the full field of view in full quality.

PTZ Cameras are commonly used in applications such as surveillance, video conferencing, live production, lecture capture and distance learning. An innovation to the PTZ camera is a built-in firmware program that monitors the change of pixels generated by the video clip in the camera.

When the pixels change due to movement within the camera's field of view, the camera can actually focus on the pixel variation and move the camera in an attempt to center the pixel fluctuation on the video chip. This results in the camera following movement. The program allows the camera to estimate the size of the object which is moving and distance of the movement from the camera.

With this estimate, the camera can adjust the camera's optical lens, zooming in and out, in an attempt to stabilize the size of pixel fluctuation as a percentage of total viewing area. Once the movement exits the camera's field of view, the camera returns to a pre-programmed or "parked" position until it senses pixel variation and the process starts over again.

Pan-tilt-zoom cameras can be an essential part of modern surveillance systems. They can direct the attention to suspicious events. From Wikipedia, the free encyclopedia. Television portal.

Read up about this project on. On this tutorial, we will explore how to control multiple servos using Python on a Raspberry Pi. What we will do is to generate a digital signal with a fixed frequency, where we will change the pulse train width, what will be "translated" as an "average" output voltage level as shown below:.

We can use this "average" voltage level to control a LED brightness for example:. Note that what matters here is not the frequency itself, but the "Duty Cycle", that is the relation between the time that the puls is "high" divided by the wave period.

This principle will be very important for us, to control our servo position, once the "Duty Cycle" will define the servo position as shown below:. The servos will be connected to an external 5V supply, having their data pin in my case, their yellow wiring connect to Raspberry Pi GPIO as below:. The first thing to do it is to confirm the main characteristics of your servos. To program a servo position using Python will be very important to know the correspondent "Duty Cycle" for the above positions, let's do some calculation:.

Let's test the servos individually. For that, open your Raspberry terminal and launch your Python 3 shell editor as "sudo" because of you should be a "super user" to handle with GPIOs :. Was easy for me to identify them and not make mistakes during the test In the final program I will use BCM. Choose the one of your preference:. If Instead, you have used BCM scheme, the last 2 commands should be replaced by:.

And, what will be the frequency generated on this pin, that for our servo will be 50Hz:. Now, let's start generating a PWM signal on the pin with an initial duty cycle we will keep it "0" :.

Now, you can enter different duty cycle values, observing the movement of your servo. So for this particular servo, the result was:. The below Terminal print screen shows the result for my tilt servo:. Note that both have similar results Your range can be different. The PWM commands to be sent to our servo are in "duty cycles" as we saw on the last step.

But usually, we must use "angle" in degrees as a parameter to control a servo. So, we must convert "angle" that is a more natural measurement to us in duty cycle as understandable by our Pi. How to do it? Very simple! Also, we know that those variations are linear, so we can construct a proportional schema as shown here:.

Let's create a Python script to execute the tests. Basically, we will repeat what we did before on Python Shell:. The core of above code is the function setServoAngle servo, angle. This function receives as arguments, a servo GPIO number, and an angle value to where the servo must be positioned. Once the input of this function is "angle", we must convert it to duty cycle in percentage, using the formula developed before. When the script is executed, you must enter as parameters, servo GPIO, and angle.

The above command will position the servo connected on GPIO 17 with 45 degrees in "elevation". The file angleServoCtrl. The "Pan" servo will move "horizontally" our camera "azimuth angle" and our "Tilt" servo will move it "vertically" elevation angle. This range will be enough to be used with a camera.These days, if you are just doing a one-off, it might be just as easy to throw commodity hardware at it.

After all, a Raspberry Pi costs less than a nice meal and it is more powerful than a full PC would have been not long ago.

A zip tie holds the servos together and potentially the web cam, too. You can see the result in the video below. It is a simple matter to set up the camera with the Pi, send some commands to the Arduino and hook up to the Internet. The serial protocol for the Arduino is simple: The Pi sends a numeric position followed by a P for pan or T for tilt at baud.

A web server and some Python handle the interface to the Internet and the human. Some of them have been a bit larger. Nicely done. Good tutorial. Is there a way to get the motion to be in smaller increments and smoother? I mean those are dirt cheap servo. I should probably add that because of the potentiometer inside most servos that they wear out. So depending on the application they may not be the best choice.

But then again anything with moving parts will eventually wear out. Yes, the movement could be much much smoother. Full ack. Although it would be a little bit more complicated to mount that way, the result would be more like you expect a pan-an-tilt can to work. The servos need 5v, so you need a NPN transistor and 2 resistors per servo.

Sorry, we're unable to complete your request

Although 2 transistors and 2 resistors are cheaper it does offer less flexibility. Sounds like way too much hardware for moving a couple of servos. The RPI is way more than you need to do everything. This would be an interesting thing to ponder with an based board.
