Hello everyone,
How can I make a device that can measure displacement in x, y, and z axis?
thanks
With knowledge, patience, mechanics and a lot of time.
Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.

Measuring x,y and z where, on the moon, in a box, underwater, in your backyard !!!!!!
How much displacement?
What is your application?
Thanks.. Tom.... 
I want to make such device that can measure the distance if it move in x,y, and z axis. The minimum distance it could read 50 cm meter. So, when I start the device it will assign it position is zero, then when i bring the device walking the street with me it will measure the distance it travel every 0.5 second. What sensor or hardware that i need?
I could be totally wrong but there was a top secret project from some 3 or 4 letter organisation that solves this verry problem. Wait, I think I know how it's called, ... GPS ? Yes, that was GPS! Don't know if you ever heard about it ...
yeah i know gps can do that, but i want the measurment occure in the device not outside of it

Be sure to patent it when you figure it out.

funny

I doubt very much you want to measure displacement, but rather distance traveled. If you start and finish at the same point, your displacement is zero. Is that actually what you want?
yes, but it will save the amount of dinstance every 0,5 second. So if the device come to where it begin after 0,5 second, there will be data saved on the device
Now I will share with you some secret knowlede with you.. Shade the windows, turn doen the lights and listen, ... Once upon a time there was a nation called the greek. As their society was based on slaverey, they could afford to loose some minor beeings to the goods. In return the gods gave them knowledge of something that is nowadays almost forgotten: trigoometry. Or was it trigonometry? Well, it's said there were books about that dark art and even today those are passed on in secrecy from generation to generation...

Well, I will tell you a little secret of my own.. You smell like a weirdo
@akkapanna, I think you are missing the point - which is that people here believe that what you want to do has not been done before.
As evidence of that, if it was something simple enough to do with an Arduino then commercial versions would be widely available.

I would get the point if it told in normal human ways, not by telling a greek secret trash
Just to be clear, you want to do this without using any GNSS such as GPS or GLONASS?

Yes, I want to do it without using any of those
So then I think your Google search term should be "pedometer".
I think they use an accelerometer to count steps from body "jerks". I imagine they would need some calibration for leg length.
Finally get a reply from normal human kind, thanks. But it should measure the distance in x,y, and z axis. I think a pedometer can not do that.
Well you could use a compass to get the bearing, then resolve the distance on that bearing into a northing and an easting.
And an altimeter will give you height....

NFC what that means...
Just to clearify: do you actually know what you want to do? If yes, I'd suggest you make a drawing and post it here. And when you have made the first drawing, I'd sugges you make a second one which shows what should happen after you moved 5 meters in 10 seconds, and post that too. then we can discuss again abiut not using geometry and GPS.
