- The project to be shared this time is about Indoor Position with 3 UWB devices.
The two UWB devices act as anchors and their positions are fixed.
On the other hand, the tag device acquires the distance from these two anchors as it moves.
Unity application uses the information obtained from the tag device, calculates the position on the x-z axis, and displays it in the virtual environment.

Dudeeeee....🔥🔥🔥 Great one
Amazing bro 💥🌟
Too cool, u da man 👍
Really cool.
Thank you very much
멋집니다! 혹시 관련 튜토리얼을 하실 생각은 없으신가요? 만들어보고싶네요!
Awesome! How did you scale a signal strength to a meter? Is there any mathematical way to calculate it or just empirical?
UWB uses the time of flight instead of signal strength for distance measurements. From this, you can figure out the distance between the Anchor device and the Tag device.
Hi, I have a project where I'm supposed to build an Indoor Positioning System for a small-scale production line (roughly about 30 workers in the whole production line). The room measures about 200m*200m. Is it possible to implement the UWB based technology to this? If so, what's the process like for adding more tags. If I were to create a web of beacons (> 2 anchors) in the manufacturing room (more than two to cover the entire room), how would that work? Thank you, your video's excellent!
In order to do indoor tracking for a large number of people, is impossible with the library currently in use. Anchor devices can communicate with only one Tag device with this library. Without addressing this issue, a mass-tracking system cannot be implemented.
Great work. Thanks. I just had one question. The UWB modules in both Anchor side and the tag are the same right? They just have different firmware inside, true?
Yes, you're right.
@@ThatProject sir any news of a better and or cheaper module? NXP has a chip but apparently there is no price. I wonder if BU01 has the original DW1000 chip or not
@@mostafanfs I have no idea about NXP. And BU01 is a cloned version of DWM1000.
@ThatProject Thank you your excellent example. Are there any specific activate order suggestion? such as, start from two anchors, then start client, then start Unity in the end?
And for two anchors' mac address BB:AA:5B:D5:A9:9A:E2:9C, should I have to change?
The MAC addresses of the two anchors must be different.
BB:AA...
DD:CC...
Amazing! Are the anchors aware of the positions of the tag too? Can the anchors be aware of an approximate location of the tag? What can I do si the anchors be aware of the tag location?
You can also know the distance to the connected tag from the anchor. One thing is that you cannot connect multiple tag devices to one anchor with the library of the DWM1000 currently in use. Only one Tag can be connected at a time.
I would like to inquire about an issue where my tags do not move during Play mode.
I have identified that this may be a problem with the Unity UDP server, as it doesn't seem to start properly or receive data.
How can I resolve this issue?
Please check if the UDP port on your PC is being used by another process. If the port is already in use, please try using a different port.
hi, how hard would it be to add one more anchor and use mpu6050 to get orientation and rotate the tag based on that.. sorry if this is a dumb question.. i am new to unity
hello.
I enjoyed the video.
Is there any method you know that can make the reaction speed faster?
I'm planning on using it as a game controller, so I need speed and accuracy.
The accuracy seems to be okay, but the reaction speed seems slow.
It doesn't matter if a person is holding something.
thank you!
For faster speed, it seems that the speed of calculating the distance from UWB should be increased. But unfortunately, this requires modifying the UWB library, so there is nothing we can do without modifying it.
well done!!
impressed APP
why your 3 lolin32 without battery connector??
It was forcibly removed due to some past project.
@@ThatProject i see
i will give you 5 connectors
hi, can I ask. after following your setup, why the tag in unity are not moving. seems like there is no error appear in my unity but still the tag are not moving after clicking play button? hope that you reply to this question. Thank you very much
Make sure your ESP32 is not having problems sending data over UDP.
@@ThatProject I already made a test using esp32 sending data over udp to my laptop using phyton and there is no problem with the hardware. May i know is there any extra settings for the unity that not shown in the video.
@@megathilmi4074 You've tested it on a Python server, but haven't tested communicating with Unity UDP. Please check if the port is properly opened in Unity. I didn’t hide anything.
Hello thanks for this video. I would like to use this technology to track a robot mower on an 800m2 plot of land. Do the anchors have enough reach for an 800m2 plot?
Unless you force power up the UWB module, it seems difficult to cover all 800m2.
Would this work inside a house? Or would the walls not let it work?
It may vary depending on the environment. Therefore, environmental testing is absolutely necessary.
Can I ask what framework did you use? Thank you
The hardware used ESP32 and was implemented in the Arduino IDE framework. For visualization, I used the Unity Game Engine.
Hello! I've recently started interfacing ESP32 UWB, any tips on how to interface multiple sensors with it? I'm also trying to do a similar project with Indoor positioning but with the tag having multiple sensors. (i.e., heart rate sensor, temp sensor...) The only problem is that I've only started interfacing with UWB. Kinda need some "professional" advice. Thanks!
You can attach any sensor you need to the Tag device. The main problem is that the DW1000 library is out-of-date and not maintained, so you have to be very careful with your code. ISR conflicts can cause the system to malfunction.
@@ThatProject Should we be careful with defining I/O pins? Recently, the output of the code similar to your project was not responding after I've added multiple sensor codes.
@@LoneXRangerz I don't know how you added the sensor, but if data is fetched by interrupt, it may conflict with the UWB chip. Please find out about the ISR.
Great project. What about lidar sensor in unity?
I guess we can use Lidar Sensor with Arduino or ESP32 in Unity and the quality of the surface data obtained from it will be very good.
@@ThatProject Yes. And you could use the unity models for collision and gravity etc...
Very interesting experiment.
In a 50 X 50 square meters room, how many anchors do we need and what is the maximum number of tags that are still allowed? thanks....
A maximum of 16 anchors can exist in any one area… if you have > 16 and all of them are within range (i.e. if one anchor can hear the other 16, then you cannot add any more near that one anchor)
In order to cover 50 meters x 50 meters, it must be delimited by a recognizable distance. For example, in my environment, it was possible to communicate with the Tag-Anchor at about 25 meters. In this case, it looks like I'll need an anchor every 25 meters.
can we move the anchor position dynamically and still get the distance between anchor and tag
Didn't you get my reply? Anyway, here you are again. Even if the anchor and tag move dynamically, the distance between the two devices can be measured continuously because they measure relative. (UWB uses the time of flight instead of signal strength for distance measurements.)
Nice Project! I also searching für this chip? I found a DMW1000 and a BU01 board. Which one should i choose? Where can i find the esp32 Adapter?
Well As I mentioned in the video BU01 is the clone version of DWM1000. DWM1000 has a way better antenna.
@@ThatProject is the DWM1000 with the square antenna and a little bit longer?
@@meinsda5983 Both DWM1000 and BU01 are the same size.
Can multiple positioning base stations be added?
As far as I know, you can install a lot of Anchors. However, it is questionable whether the DW1000 library currently in use can handle this.
Hi, My Tag code is not connecting with the wifi. can you help in this?
UWB and WIFI modules have nothing to do with each other. Please check your WIFI credentials.
What are the codes you used in C#?
You can find it in the video description.
@@ThatProject is there guides on how to use unity? sorry I've done the project before but only using python and now I want to try using unity for my visualization
@@r.h.d9933 Unfortunately, I stopped currently offering tutorials for Unity. Please googling or find a tutorial video that is best for you on TH-cam.
Can the system simultaneously track say 40 tags?
No. This is not possible with currently published libraries.
@@ThatProject oh :(….. shame
Hello, I am new to Unity and wanted to ask how do you create your UDP server in Unity? Thanks
Everything for network communication is already included in Unity in the .Net Framework. Use this to build your own server. github.com/manlaig/basic_multiplayer_unity
I used this UDP server. It's simple but works great on a local network.
@@ThatProject Hi Eric, thanks for the information. I'll definitely check this out. When trying to connect my tag to the Unity Program, I'm faced with two errors.
Before I press "play", a yellow error appears at the bottom of my Unity saying "Assets\Scripts\DataHandler.cs(23,29): warning CS0414: The field 'DataHandler.rightAnchorShortName' is assigned but its value is never used".
Is this an issue?
And when I press "play", a red error appears saying "SocketException: Only one usage of ach socket address(protocol/network address/port) is normally permitted."
Have you faced these issues before? Thanks very much
@@temmiethy166 You can ignore the first warning. It's just a warning about unused variables.
Seems like the port in your program is already in use in another program, you should use another port or kill the active process to make the port free.
I use port number 8080 in this project. Please try again after setting a port number other than this port number for Unity and your hardware respectively.
@@ThatProject Hi, how do you check that the ESP32 is connected to the UDP port in Unity? I've seen that there are tests like HTTP GET and POST but I think those are for TCP right? Even after changing my port number on the tag and in the Unity editor, the "play" window just displays the server IP address and the port number and the tag cannot move. Thanks
@@temmiethy166 If you look at my ESP32 code, you can see that I use #include . Please check my source code again.
Hi! Is it possible to send the location via SMS messaging?
You can send SMS using GSM module. If Wifi is available, you can send SMS via paid API. th-cam.com/video/SP4pvYCQAfc/w-d-xo.html
is there any unity project/code for "ESP32 DW3000"
I don't have a real project with DW3000 yet.
can esp32 wrooms support this project
It's not matter. All you need to run this project is to use a UWB chip (DWM1000).
sir can you put 3 anchors for a 3rd dimension (altitude) there?
It's still being prepared for testing. I need more BU01.
@@ThatProject even 2d requires 3 anchors, without 3 anchors how did you even triangulate your 2D position in this video. It should be on either side of the circle
@@SuperJoelgeorge You're talking about 3 devices for 2D position measurement, right? Here, two Anchor and one Tag devices were used.
@@ThatProject yes what I'm telling is, for triangulation itself 3 anchors will be required in a 2D space
@@SuperJoelgeorge Now I got it. Yes, we need 3 anchors for triangulation. So you will try it sooner or later?
Please.3 axis dwm1000
I'd like to try that too.
Hi, is there any readme files about how to run the unity file .
It doesn't have the specific readme file for that. Any issues while running the Unity project?
@@ThatProject yes. while running the unity project it wasnt receiving any data. udp.Available was always 0. i checked receiving the data in the same ip and port using a python file and it was successful but the unity file isnt receiving the data
@@KengCat-kt6rt Perhaps you need to open a specific port in the firewall of the system you are using. Do you use Windows?
@@ThatProject yes i use windows. I was able to get the data by receiving it via a python file and sending it again to the unity via localhost but communication between uwb and unity is blocked
@@KengCat-kt6rt Not sure this is for your case but check it out. forum.unity.com/threads/starting-host-server-shows-port-is-closed.1470026/

That's the information about your DW1000 chip and settings. Also, you can change the Preamble length and Frequency for your environment.
@@ThatProject
well . u mean that it is common to send this message and everything is in order. However, in this particular case, since I am using Unity, I'm not receiving any immediate response.
I am interested to know if it would be possible for us to connect directly.
@@user-so4ce5hr4w That's weird. It's because UDP connection, you can get the packet as soon as the other one is sent in Unity. I think you need to check both of sender and receiver to address this issue and Your WiFi router too.
@@ThatProject
Im using a grean board similar to the red one you had used it .
It seems the i got same results when i connect the board without the Chip (bu01)
So how can i make sure its working ?
@@user-so4ce5hr4w I'm not sure if you would have gotten the same results without Bu01.
