# 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.
## Description
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.
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.
## Photos
![Kobuki](/docs/assets/KobukiPhoto.jpg)
## 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.
## 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);
}
```

# OpenCV
## Requirements
We want that the camera we want it to detect what is happening on the video feed and identify it so it can identify dangers.
## Issues
* OpenCL not grabbing gpu
* Solution: https://github.com/Smorodov/Multitarget-tracker/issues/93
## Installation
### Dependencies
* 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

# Sensor behuizing
Voor de sensoren op onze Kobuki wouden wij graag een behuizing zodat deze sensoren niet los liggen op de Kobuki.
Deze behuizing had een paar eisen en die eisen waren als volgt
- Hij moet klein zijn zodat hij niet veel ruimte in neemt op de Kobuki.
- De behuizing moet makkelijk vast te maken zijn aan de Kobuki.
- In de behuizing moet een esp32 passen en de 3 sensoren.
- De behuizing moet makkelijk uit elkaar te halen zijn zodat als we onderhoud moeten plegen dit makkelijk kan.
Met deze eisen zijn we uiteindelijk een behuizing gaan maken in onshape.
Onshape is gratis ontwerp software wat te gebruiken is via je browser.
Hierdoor hoef je dus geen applicatie te runnen op je computer en kan je op elk apparaat inloggen om zo gemakkelijk door te gaan aan je ontwerp.
Ik (Yannick) heb voor deze software gekozen omdat ik deze software al veel vaker heb gebruikt en hier dus al bekend mee ben.
Uiteindelijk zijn we op het volgende design uitgekomen.
![Afbeelding van de behuizing](images/Behuizingfoto1.png)
![Afbeelding van de behuizing van bovenaf](images/Behuizingfoto2.png)
Wij hebben gekozen voor dit design omdat dit de breedte en lengte heeft van een esp32 dus de esp past precies waardoor wij hem niet nog extra vast hoeven te zetten.
Er zitten gaten in de zijkant van het bakje voor de kabel en voor een 5 volt kabel voor de MQ5 sensor.
De dht11 sensor past er precies in en deze blijft daardoor precies vast zitten.
Voor de M5stack sensor is er een gat gemaakt zodat deze kabel erdoorheen past en vervolgens wordt deze sensor op de bovenkant van de behuizing vastgeplakt.
Voor de MQ5 sensor is een gat gemaakt waar de sensor door heen kan en het printplaatje wordt aan de onderkant vast gemaakt met stevige M3 tape.
In de onderkant van de behuizing zitten 2 gaten hiermee kan de behuizing goed vastgemaakt worden aan de kobuki.
De onderkant en de bovenkant van de behuizing zijn makkelijk uit elkaar te halen omdat deze doormiddel van 4 sterke magneten aan elkaar vast zitten.
Hierdoor is het ook makkelijk om onderhoud te plegen omdat het bakje door de magneten makkelijk uit elkaar te halen is maar niet zo makkelijk dat hij door trillingen los kan komen.

# Sensor onderzoek
In dit bestand gaan we onderzoek doen naar de sensoren die we willen gebruiken op de Kobuki.
Hierin gaan we meerdere sensoren vergelijken met elkaar en kijken welke wij het beste kunnen gebruiken voor ons project.
## Probleem
Voor ons project moeten wij een manier vinden om gassen/stoffen te detecteren zodat je in een gebouw weet waar je niet veilig naartoe kan.
## De vraag
> Welke sensoren kunnen wij het beste gebruiken om schadelijke gassen/stoffen te vinden in een gebouw ?
## Voorwaarden
De voorwaarden waar de sensors aan moeten voldoen zijn:
- De sensoren moeten op de kobuki passen.
- We moeten zo weining mogelijk sensoren gebruiken zodat we genoeg plek over houden voor andere onderdelen van de Kobuki.
## Hoe aansluiten
Wij gaan deze sensoren aansluiten op een esp32 en deze laten wij via MQTT de gegevens doorsturen naar de raspberry pi.
## De sensoren.
Wij zijn uitgekomen op 3 sensoren.
- De dht11 sensor
- De tvoc/eC02 Gas Unit.
- Gravity: Elektrochemische zuurstof-/O2-sensor (0-25%Vol, I2C) SEN0322
- Gassensor MQ-5 module (OT2018-D55)
Wij hebben voor de Dht11 en de tvoc/eC02 gas unit gekozen omdat wij deze bij james konden lenen. En wij hebben gekozen voor de Gassensor MQ-5 module (OT2018-D55) Omdat dit een mooie kleine sensor is die wij makkelijk kwijt kunnen op de kobuki.
Voor de o2 sensor hebben wij gekozen voor de Gravity: Elektrochemische zuurstof-/O2-sensor (0-25%Vol, I2C) SEN0322. Deze sensor is helaas op het moment van schrijven (29-10-2024) niet op voorraad dus deze sensor kunnen wij helaas nog niet toevoegen. Zodra deze sensor op voorraad is zal ik deze bestellen en aan de esp toevoegen.
## Sensor uitleg
#### Dht11
De dht11 is een eenvoudige en goedkope sensor die wordt gebruikt om de temperatuur en luchtvochtigheid te meten.
De sensor bevat de volgende onderdelen om te werken:
- Een thermistor : Dit is een component die temperatuur meet door variaties in elektronische weerstand.
- Een capacitieve vochtigheidssensor : Deze meet de relatieve luchtvochtigheid door de verandering in het materiaal tussen de condensatorplaten te meten. Deze verandering gebeurt door de waterdamp in de lucht.
- Een geïntegreerde microcontroller : Deze microcontroller verwerkt de gegevens van de sensoren en zet deze om in een digitaal signaal.
Het meetbereik van de sensor is 0 tot 50 graden voor temperatuur en voor de luchtvochtigheid is het 20 tot 90%
Hierbij is de temperatuur tot ±2 graden nauwkeurig en de luchtvochtigheid ±5 procent.
De DHT11 kan aangesloten worden op een 3.3 of 5 volt voeding.
Wij kunnen deze sensor dus zonder problemen compleet aansluiten op de esp32s3
#### Tvoc/eC02 Gas Unit
De M5Stack TVOC/eCO2-Gassensensor-eenheid (SGP30) is een compacte sensor ontwikkeld om vluchtige organische stoffen (TVOC) en schijnbare CO₂-concentraties (eCO2) te meten.
Deze component maakt gebruik van de SGP30-sensor van Adafruit
De SGP30 is gebaseerd op een metal-oxide (MOX) halfgeleidertechnologie.
Deze technologie detecteert veranderingen in elektrische weerstand bij blootstelling aan vluchtige organische stoffen (VOC's),
zoals ethanol en aceton.
De sensor bevat ingebouwde algoritmes om de gemeten VOC waarden om te zetten in tvoc en eco2.
- TVOC : Dit is de totale concentratie vluchtige organische stoffen.
- ECO2 : Dit is een geschatte koolstofdioxideconcentratie.
Dit is een schatting op basis van de VOC metingen.
Deze sensor werkt op 3.3 en 5 volt dus ook voor deze sensor kunnen wij de esp32s3 gebruiken.
#### MQ5 Gassensor
De MQ5-gassensor is een veelgebruikte sensor voor het detecteren van brandbare gassen, zoals aardgas (methaan), vloeibaar petroleumgas (LPG), waterstof en koolmonoxide. Het werkt op basis van veranderingen in elektrische weerstand van het sensorelement wanneer het wordt blootgesteld aan specifieke gassen.
De kern van de MQ5 sensor is een chemisch gecoat metalen oxide (meestal tinoxide).
Dit materiaal reageert op de aanwezigheid van brandbare gassen.
Wanneer de sensor gasdeeltjes detecteert, reageren deze met zuurstofionen op het oppervlak van het tinoxide. Deze reactie veroorzaakt een verandering in de elektrische geleidbaarheid (weerstand) van het materiaal.
De verandering in weerstand wordt door een elektronisch circuit omgezet in een elektrisch signaal dat de concentratie van gas vertegenwoordigt.
De MQ5 sensor heeft ook een ingebouwde verwarmingsspiraal die het sensorelement op een hoge temperatuur houdt (ongeveer 300-500°C). Deze temperatuur zorgt ervoor dat gassen efficiënt reageren met het tinoxide-oppervlak.
Het enige nadeel van deze sensor is dat hij niet selectief is dus de sensor kan geen onderscheid maken tussen bijvoorbeeld methaan en lpg.
## Aansluitschema
![Afbeelding aansluitschema](images/Aansluitschema_sensors.png)
Hierboven is te zien hoe wij de sensoren hebben aangesloten op de esp32.

# **Projectplan - robot voor Gevaarlijke Omgevingen**
### Projectbeschrijving
### Projectbescrhijving
Het project betreft de ontwikkeling van een robot voor gevaarlijke omgevingen. De robot is bedoeld om gevaarlijke situaties te verkennen en in kaart te brengen. De robot is uitgerust met verschillende sensoren en daar gaan we zelf nog een camera en andere sensoren op zetten om de omgeving te verkennen. De data wordt verzameld en geanalyseerd om een beeld te krijgen van de situatie. De robot kan worden ingezet in verschillende situaties, zoals branden, instortingen en andere gevaarlijke situaties.
### 1. Organisatorische Context
Bij de ontwikkeling van de robot zijn verschillende factoren van belang. Maatschappelijke veranderingen zoals duurzaamheid en de toenemende vraag naar technologische oplossingen voor gevaarlijke werkomgevingen spelen een grote rol. De robot kan worden ingezet voor gevaarlijke situaties waar bijvoorbeeld geen mensen naar binnen kunnen.
**Vervolgstappen:**
- Focus op duurzaamheid en herbruikbaarheid.
- Focus op duurzaamheid en herbruikbaarheid.
- Inzetten op veiligheid en efficiëntie.
### 2. Ethiek
Ethische vragen staan centraal bij de ontwikkeling van de robot. Er moet rekening gehouden worden met de veiligheid van de gegevens van gebruiker. Het minimaliseren van de milieu-impact door duurzame materialen te gebruiken zoals hout en metaal. Privacy speelt ook een belangrijke rol. De verzamelde data moet veilig worden gebruikt en opgeslagen en het moet de EU privacy richtlijnen volgen.

## Wat gaan we met de sensoren doen?
### Camera
De camera word gebruikt om foto's te maken in de omgeving in het geval van informatie verkrijgen voor als de robot bijvoorbeeld vast zit, geeft ook optie om informatie te krijgen zonder op de plek zelf te zijn.
### GPS module
De GPS module word gebruikt om de locatie van de robot te bepalen en aan te geven waar bijzonderheden bevinden.
### Temparatuur, TVOC en ECO2 sensor
Deze sensoren zijn bedoeld om de omgeving te meten en te kijken of de omgeving veilig is voor mensen om in te gaan.
### LDR sensor
De LDR sensor word gebruikt om de lichtsterkte te meten en te kijken of er een lamp op de robot aan moet gaan voor de camera.
### Time of Flight sensor
De Time of Flight sensor word gebruikt om de afstand te meten tussen de robot en de muur, zodat de robot niet tegen de muur aan botst.
## Het project
Bij brand of op fabrieksterreinen met gevaarlijke stoffen kan het nodig zijn om een verkenning te
doen van een verdachte omgeving. Het is dan niet verstandig om mensen naar binnen te sturen, in
die gevallen vallen de hulpdiensten terug om een verkenningsrobot. Het doel van het project is het

# Hoofd en deelvragen
**Wat is de aanleiding?**
De aanleiding is de de behoefte aan veilige communicatie tussen apparaten. Dit is belangrijk omdat onbeveiligde dataoverdracht kan leiden tot datalekken.
**wat is het probleem/behoefte en waaruit blijkt dat?**
Het probleem is dat data die tussen apparaten wordt verstuurd kwetsbaar kan zijn. Dit blijkt nadat wij te horen hebben gekregen dat er niet goed was omgegaan met communicatie tussen apparaten.
**Wie heeft het probleem/behoefte?**
ons groepje, maar ook bijvoorbeeld grote bedrijven waar het heel belangrijk is dat data veilig wordt verstuurd zonder dat het in de verkeerde handen valt.
**Wanneer is het probleem/behoefte ontstaan?**
Het probleem is ontstaan nadat wij te horen hebben gekregen dat er niet goed was omgegaan met communicatie tussen apparaten.
**Waarom is het een probleem?**
Het is een probleem omdat onbeveiligde communicatie kan leiden tot datalekken waaronder privacy. Hiermee kunnen bedrijven in de problemen komen.
**Waar doet het probleem/behoefte zich voor (afbakening)?**
Het probleem komt voor in verschillende sectoren waar data tussen apparaten wordt verstuurd. Dit kan zijn in de zorg, industrie, op kantoor, maar ook met IoT projecten wat je thuis kan hebben.
## Hoofdvraag
Welke communicatieprotocol geeft de mogelijkheid om veilig en betrouwbaar te communiceren tussen IoT apparaten?
## Deelvragen
1. Wat houdt veilige en betrouwbare communicatie tussen apparaten in?
2. Welke protocollen zijn er om veilig en betrouwbaar te communiceren tussen apparaten?
3. Wat zijn de voor- en nadelen van de verschillende protocollen?

# Smart leerdoelen
Na de retrospective die ik heb gedaan, heb ik besloten om de volgende smart leerdoelen te stellen:
1 **Ik wil in de volgende blok meer gaan opletten op mijn teamgenoten om zo goed te weten waar iedereen mee bezig is.**
**specifiek:**
ik heb in onze groep de taak als voorzitter alleen merk ik op dit moment dat ik niet goed weet waar iedereen mee bezig is. Dat is niet handig omdat ik dan als voorzitter niet goed kan inschatten of iedereen op schema ligt.
**meetbaar:**
Ik wil dat ik aan het einde van de blok meer contact heb gehad met mijn teamgenoten en dat ik weet waar iedereen mee bezig is. Dit zorgt ervoor dat ik beter kan inschatten of iedereen op schema ligt en of ik moet ingrijpen.
**acceptabel:**
Dit is acceptabel omdat ik als voorzitter de taak heb om te zorgen dat iedereen op schema ligt en dat iedereen weet wat hij/zij moet doen. Zonder deze informatie kan ik niet goed mijn taak uitvoeren waardoor de teamgenoten niet goed kunnen werken.
**realistisch:**
Dit is realistisch omdat ik als voorzitter de taak heb om te zorgen dat iedereen op schema ligt en dat iedereen weet wat hij/zij moet doen.
**tijdgebonden:**
Ik wil dit doel behalen aan het einde van de blok. Dit is een realistische tijd omdat ik dan genoeg tijd heb om dit doel te behalen. Ik kan mij later ook nog tijdens de opleiding verbeteren op dit punt.
---
2 **Ik wil in de volgende blok meer gaan opletten op mijn eigen documentatie.**
**specifiek:**
In tegen stelling tot vorig jaar hou ik nu mijn documentatie niet goed bij. Dit is niet handig omdat ik dan niet goed kan zien wat ik daadwerkelijk heb gedaan en wat ik allemaal heb geleerd. Ook is het fijn dat ik dan kan terug kijken op mijn werk als ik het later nodig heb. Ik wil daarom minimaal 2 keer per week mijn documentatie bijwerken.
**meetbaar:**
Ik wil dat ik aan het einde van de blok mijn documentatie goed heb bijgehouden. Dit zorgt ervoor dat ik kan zien wat ik heb gedaan en wat ik allemaal heb geleerd. Ook kan ik dan terug kijken op mijn werk als ik het later nodig heb.
**acceptabel:**
Dit is acceptabel omdat ik dan toekomst gericht kan werken. Ik kan dan terug kijken op mijn werk als ik het later nodig heb. Ook kan ik dan zien wat ik heb gedaan en wat ik allemaal heb geleerd.
**realistisch:**
Dit is realistisch omdat ik dit vorig jaar ook heb gedaan. Ik weet hoe ik mijn documentatie moet bijhouden en wat ik allemaal moet opschrijven. Mijn eis van 2 keer per week is ook realistisch omdat ik dan genoeg tijd heb om mijn documentatie bij te werken.
**tijdgebonden:**
Ik wil dit doel behalen aan het einde van de blok. Dit is een realistische tijd omdat ik dan genoeg tijd heb om mijn documentatie bij te werken.

# kobuki
# last sprint i have been busy with the website
# my job was to make an controller on the website for the kobuki
# so that we can control the kobuki with the website
# i did this using a protocol called MQTT
# mqtt is a protocol that is used to send messages between devices
# this is different from the normal protocol that i used last year
# it was a bit difficult to get the kobuki to work with the website
# next sprint i will be working on a sensor
# i will do some research on the different sensors that we can use
#
