+# 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);
+}
+```

+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
-* 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
