-# Editing this README
-
-When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thanks to [makeareadme.com](https://www.makeareadme.com/) for this template.
-
-## Suggestions for a good README
-
-Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
-
-## Name
-Choose a self-explaining name for your project.
+# TI-project - Kobuki
 
 ## Description
-Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
+This project is a kobuki that drives around in dangerous areas and detects objects in its path. It uses a camera to detect objects. The kobuki is able to drive around in a room and detect objects.
 
-## Badges
-On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
+## Photos
+![Kobuki](/docs/assets/KobukiPhoto.jpg)
 
-## Visuals
-Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
-
-## Installation
-Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
-
-## Usage
-Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
-
-## Support
-Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
-
-## Roadmap
-If you have ideas for releases in the future, it is a good idea to list them in the README.
-
-## Contributing
-State if you are open to contributions and what your requirements are for accepting them.
-
-For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
-
-You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
-
-## Authors and acknowledgment
-Show your appreciation to those who have contributed to the project.
-
-## License
-For open source projects, say how it is licensed.
-
-## Project status
-If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.

+# Systemd Services
+
+# What is a service
+A service is a program or script that runs in the background and is managed by the system. Services are started at boot time and run until the system is shut down. Services can be started, stopped, and restarted by the system administrator.
+
+# How to manage services on systemD
+
+## Starting a service
+To start a service, use the `systemctl start` command followed by the service name. For example, to start the `apache2` service, use the following command:
+
+```bash
+sudo systemctl start apache2
+```
+
+## Stopping a service
+To stop a service, use the `systemctl stop` command followed by the service name. For example, to stop the `apache2` service, use the following command:
+
+```bash
+sudo systemctl stop apache2
+```
+
+## Restarting a service
+To restart a service, use the `systemctl restart` command followed by the service name. For example, to restart the `apache2` service, use the following command:
+
+```bash
+sudo systemctl restart apache2
+```
+
+## Enabling a service
+To enable a service to start at boot time, use the `systemctl enable` command followed by the service name. For example, to enable the `apache2` service, use the following command:
+
+```bash
+sudo systemctl enable apache2
+```
+
+## Creating a new service
+To create a new service, you need to create a new service file in the `/etc/systemd/system/` directory. The service file should have a `.service` extension and contain the following sections:
+
+### Example service file:
+
+```bash
+[Unit]
+Description=FlaskApp #description of the service
+After=network.target #start the service after the network is up
+
+[Service]
+User=ishak #start the service as a specific user
+WorkingDirectory=/home/ishak/rooziinuubii79/src/Python/flask/web/ #working directory of the service
+ExecStart=/usr/bin/gunicorn -w 3 -b 127.0.0.1:5000 app:app #command to start the service
+```

+# MQTT
+
+## What is MQTT?
+MQTT is a lightweight messaging protocol made for IOT devices. It allows efficient communication between IoT devices, servers, and applications by allowing them to
+publish and subscribe to messages.
+
+
+## How to connect
+To connect to a MQTT server you need to create a instance of the class.
+
+Example:
+```cpp
+// server adress, Client ID, Client Username, Client Password
+MqttClient client("ws://145.92.224.21/ws/", "KobukiRPI", "rpi", "rpiwachtwoordofzo"); // create a client object
+```
+Later in the setup function you need to call ```client.connect();``` to connect to the mqtt server.
+```cpp
+    client.connect();
+```
+
+When you've connected and the instance is initiated you can subscribe to topics or send messages to topics.
+
+
+## Subscribing and receiving messages
+Example subscribing to a topic:
+```cpp
+void setup(){
+    client.subscribe("home/commands");
+}
+```
+
+Example receiving latest message from a topic:
+```cpp
+std::string foo(){
+    std::string latestMqttMessage = "";
+    latestMqttMessage = client.getLastMessage();
+    return latestMqttMessage;
+}
+```
+
+If you want to subscribe to mulitple topics you need to initiate multiple instances of the mqtt class.
+
+## Publishing messages
+Example publishing a message:
+```cpp
+void foo(std::string Message){
+    //channel, payload
+    client.publishMessage("kobuki/example", Message);
+}
+```

 ## Issues
-
 * OpenCL not grabbing gpu
 * Solution: https://github.com/Smorodov/Multitarget-tracker/issues/93
 
 ## Installation
 ### Dependencies
-* glew
-* opencv
+* glew (for openGL)
+* opencv C++ lib
+
+How to install OpenCV
+```bash
+ sudo apt-get install libopencv-dev
+```
+
+## Code explanation
+
+### Opening the camera with OpenCV
+```cpp
+    VideoCapture cap(0);     //Open the default camera (0), points to /dev/video0. You could also change the number to the preferred camera
+    if (!cap.isOpened()) { //if camera is not opened throw a error message
+        cerr << "Error: Could not open camera" << endl;
+        return;
+    }
+```
+
+## Taking a picture and storing it in a variable
+```cpp
+    Mat frame; //create a new Matrix variable called frame
+    while (true) {
+        cap >> frame; // Capture a new image frame. 
+        if (frame.empty()) { //if the variable frame is not filled return a error
+            cerr << "Error: Could not capture image" << endl;
+            continue;
+        }
+```
+
+## Encoding the image for sending it over MQTT
+```cpp
+        vector<uchar> buf; //create a dyanmic buffer for the image 
+        imencode(".jpg", frame, buf); //encode the image to the buffer
+        auto* enc_msg = reinterpret_cast<unsigned char*>(buf.data());
+```
+
+```cpp
+
+void CapnSend() {
 
 
 
 
+        // Convert the image to a byte array
+
+
+        // Publish the image data
+        client.publishMessage("kobuki/cam", string(enc_msg, enc_msg + buf.size()));
+        cout << "Sent image" << endl;
+
+        std::this_thread::sleep_for(std::chrono::milliseconds(300)); // Send image every 1000ms
+    }
+}
+```

+# Kobuki driver 
+
+## How do i communicate with the kobuki
+You can communicate with the kobuki by usb serial or the big serial port on the front. We chose the usb port paired with a raspberry Pi.
+
+The Kobuki sends a message every 200ms with a baudrate of 115200. It sends all the sensordata and the message always starts with the same 2 bytes 0xAA and 0x55.
+
+## Kobuki payloads
+To communicate with the kobuki we need to send payloads to the kobuki. These are structured the same as the payloads that the kobuki sends.
+
+```cpp
+  unsigned char KobukiPayload[11] = {
+      0xaa,               // Start byte 1
+      0x55,               // Start byte 2
+      0x08,               // Payload length (the first 2 bytes dont count)
+      0x01,               // payload type (0x01 = control command)
+      0x04,               // Control byte or additional identifier
+      actual_speed % 256, // Lower byte of speed value (max actual_speed 1024)
+      actual_speed >> 8,  // Upper byte of speed value
+      0x00,               // Placeholder for radius
+      0x00,               // Placeholder for radius
+      0x00                // Placeholder for checksum (will be applied later)
+  };
+```
+You can also find the documentation about the payloads on the kobuki website

+#  Etische aspecten van het project
+
+## Visie op de ethische aspecten van het Kobuki-project
+
+Etische aspecten zijn heel belangrijk in het project, al ben ik wel van mening dat je niet alles kan voorkomen en ook kan waarborgen.
+
+## Privacy
+
+Als je bijvoorbeeld kijkt naar het gedeelte privacy, dan is het heel moeilijk om te kijken wat je gaat doen met die gegevens. Ik ga een camera gebruiken op de robot om zo te kijken 
+waar de robot is en wat hij allemaal ziet. Als de robot in een brandende huis komt en dan een persoon ziet, is het wel belangrijk om die persoon goed te kunnen zien. Je zou dan niet kunnen zeggen dat je die persoon bijvoorbeeld moet vervagen, want je moet wel kunnen zien wat de status is van die persoon.
+Ook is het dan belangrijk om te kijken wat je met die gegevens gaat doen, ga je ze opslaan voor eventuele later gebruik of verwijder je ze direct. Het is heel lastig te bepalen wanneer je op zo een moment privacy schendt. 
+
+## Betrouwbaarheid
+
+Ik vind dat je de betrouwbaarheid van de robot wel moet waarborgen,
+want als ik de robot in een brandend huis stuur en hij valt uit, dan kan dat heel gevaarlijk zijn voor de persoon die in dat huis zit. Daar vind ik dat je meer rekening mee moet houden dan met de privacy van de persoon. Het is de bedoeling dat de robot hulpmedewerkers gaat helpen en niet hun werk moeilijker maakt.
+
+## Impact op hulpverleners & maatschappij
+
+Als meerdere hulpmedewerkers de robot gaan gebruiken en het word een soort van standaard, dan is het wel belangrijk dat de robot betrouwbaar is en dat je erop kan vertrouwen. Het gaat immers om mensenlevens en dat is wel het belangrijkste. Het is uiteindelijk de bedoeling dat de robot hulpverleners zal helpen en niet hun werk lastiger moet maken. Als de robot een standaard hulpmiddel wordt moet hij wel gebruiksvriendelijk zijn en goed kunnen helpen. De robot moet ook zo goed mogelijk werken om zo de vertrouwen te behouden van de mensen. Als de robot fouten blijft maken en niet betrouwbaar is zullen minder mensen het gebruiken. Ik vind dan ook dat de gebruik van de robot heel transparant moet zijn. Hoe word de robot aangestuurd, hoe vergelijkt hij situaties en hoe hij daarmee omgaat. 
+Als je daar al heel duidelijk in bent bouw je al wat sneller vertrouwen van de mensen op. 
+
+Ik vind dat in dit project de ethische aspecten heel belangrijk zijn en dat je daar ook rekening mee moet houden. 
+Bij betrouwbaarheid en de impact die de robot kan hebben op de maatschappij en de hulpverleners moet je wel goed over nadenken. 
+Je werkt immers met mensenlevens en dat is wel het belangrijkste. Privacy is ook heel belangrijk, maar ik vind dat je daar wel wat soepeler mee om kan gaan.

+# Welke communicatieprotocol geeft de mogelijkheid om veilig en betrouwbaar te communiceren tussen IoT apparaten?
+
+Auteur: Ishak Jmilou
+
+Datum: 17-12-2024
+
+
+
+---
+
+
+## Inleiding
+
+In dit verslag wordt er gekeken naar de verschillende communicatieprotocollen die gebruikt kunnen worden om veilig en betrouwbaar te communiceren tussen IoT apparaten. Er wordt gekeken naar de verschillende protocollen en de voor- en nadelen van elk protocol.
+
+---
+
+# Samenvatting
+
+In dit verslag worden de communicatieprotocollen MQTT, HTTP, WebSockets en CoAP vergeleken op het gebied van veilige en betrouwbare communicatie tussen IoT-apparaten. Veilige communicatie omvat gegevensversleuteling en authenticatie, terwijl betrouwbaarheid verwijst naar het verzenden en ontvangen van gegevens zonder verlies. Op basis van deze overwegingen wordt MQTT aanbevolen voor situaties waar zowel veiligheid als betrouwbaarheid cruciaal zijn in IoT-communicatie.
+
+## 1. Wat houdt veilige en betrouwbare communicatie tussen apparaten in?
+
+Als je werkt met IoT-apparaten, is het belangrijk dat de communicatie tussen deze apparaten veilig en betrouwbaar is. Iot-apparaten verzamelen gegevens over de omgeving en communiceert deze tussen apparaten over het internet. Als deze communicatie niet veilig is, kunnen hackers deze gegevens onderscheppen en gebruiken(Ministerie van Algemene Zaken, 2022). Je wilt voorkomen dat hackers toegang krijgen tot gevoelige informatie zoals persoonlijke gegevens of bedrijfsgeheimen. Daarom is het belangrijk dat de communicatie tussen apparaten veilig en betrouwbaar is. Een protocol is een set regels die bepalen hoe apparaten met elkaar communiceren. Er zijn verschillende protocollen die gebruikt kunnen worden om veilig en betrouwbaar te communiceren tussen IoT-apparaten.
+
+## 2. Welke protocollen zijn er om veilig en betrouwbaar te communiceren tussen apparaten?
+
+Een communicatieprotocol is een set regels die bepalen hoe apparaten met elkaar communiceren(Paul Christiano, 2023). Er is voor elk project een ander protocol dat het beste past. In dit geval is het belangrijk dat de communicatie veilig en betrouwbaar is. De protocollen die ik ga vergelijken zijn MQTT, HTTP, WebSockets en CoAP. Wat belangrijk is om te onderzoeken is hoe de protocollen omgaan met veiligheid en betrouwbaarheid. Veiligheid kan worden bereikt door gegevens te versleutelen en te authenticeren. Betrouwbaarheid kan worden bereikt door gegevens te verzenden en te ontvangen zonder verlies.(Paul Christiano, 2023).
+
+## 3. Wat zijn de voor- en nadelen van de verschillende protocollen?
+
+![alt text](image.png)
+
+Zoals te zien is in de tabel is CoAP minder betrouwbaar dan de andere protocollen. Dit komt, omdat CoAP gebruik maakt van UDP wat ervoor zorgt dat het sneller is maar niet betrouwbaar met de berichten die hij stuurt(Darek Fanton, 2023). Websockets is een goede protocol alleen is het niet altijd geschikt voor lichtgewicht apparaten. HTTP maakt gebruik van TCP wat betrouwbaar is, maar het nadeel van HTTP is dat het elke keer een nieuwe verbinding moet maken. Dit kan een probleem zijn als je veel berichten moet versturen. MQTT is een lichtgewicht protocol dat betrouwbaar is en verschillende niveaus van kwaliteit van de berichten ondersteunt. Het is ook mogelijk om gegevens te versleutelen en te authenticeren met MQTT. Dit maakt het een goede keuze voor veilige en betrouwbare communicatie tussen IoT-apparaten.
+
+## 4. Conclusie
+
+Er zijn verschillende protocollen die goed gebruikt kunnen worden voor IoT apparaten. Aangezien voor mijn project veiligheid en betrouwbaarheid op één staat heb ik gekozen voor MQTT. Dit protocol is lichtgewicht, betrouwbaar en ondersteunt verschillende niveaus van kwaliteit van de berichten. Het is ook mogelijk om gegevens te versleutelen en te authenticeren met MQTT. Dit maakt het een goede keuze voor veilige en betrouwbare communicatie tussen IoT-apparaten.
