+## Installation
+
+### Requirements
+
+- Kobuki robot
+- Raspberry Pi (minimum 3B)
+- Camera
+- power supply for Raspberry Pi
+- laptop or computer
+
+### Steps
+
+1. **Install Python and Pip**
+   - Ensure you have Python installed on your system. You can download it from [python.org](https://www.python.org/).
+   - Pip is the package installer for Python. It usually comes with Python, but you can install it separately if needed.
+
+2. **Clone Our Repository**
+    - Clone our repository to your local machine doing the following :
+        - Open your terminal
+        - Change the current working directory to the location where you want the cloned directory.
+        - Type `git clone https://gitlab.fdmci.hva.nl/technische-informatica-sm3/ti-projectten/rooziinuubii79.git
+  
+3. **Install the required packages**
+    - Install the following packages on the server: "docker docker-buildx mosquitto nginx"
+    - Install the following packages on the Raspberry Pi: "g++ make cmake", https://github.com/eclipse-paho/paho.mqtt.c, https://github.com/eclipse-paho/paho.mqtt.cpp
+
+
+
+4. **Run the project**
+
+    #### Server side
+    - Run the following commands in the terminal to start the website:
+        - `cd src/Python/flask`
+        - `sudo docker buildx build -t flaskapp:latest .`
+        - `sudo docker run --network="host" --restart=always flaskapp:latest`
+    - Run the following commands in the terminal to start the MQTT broker:
+        - `cd src/config/server/`
+        - `mosquitto -c mosquitto.conf`
+    - Run the following commands in the terminal to start the Nginx server:
+        - `cd src/config/server/`
+        -  `cp nginx.conf /etc/nginx/nginx.conf`
+        -  `cp nginx-sites.conf /etc/nginx/sites-enable/nginx-sites.conf`
+
+
+    #### Raspberry Pi side
+    - Run the following commands to build and start the driver:
+        - `cd src/C++/Driver`
+        - `cmake ..`
+        - `make`
+        - `./kobuki_driver`
+    - Run the following commands to autostart the driver on startup of the Raspberry Pi:
+        - `cd src/config/rpi/`
+        - `cp kobukiDriver.service /etc/systemd/system/kobukiDriver.service`
+        - `systemctl enable kobukiDriver.service`
+        - `systemctl start kobukiDriver.service`
+
+## Extra notes
+Dont forget to change the IP address in the `src/C++/Driver/src/main.cpp` file to the IP address of the server.

+#  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?
+

+
+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.
