Introduction to Python programming for the course TPK4128 Industrial Mechatronics at the Department of Mechanical and Industrial Engineering, NTNU, Norwegian University of Science and Technology

The task is to build a Python module that implements a socket server that fetches images from a webcam and sends it over a TCP/IP or UDP socket when it gets a request from a client.

1. Install Ubuntu in a virtual machine, e.g., VirtualBox.
2. Mount the the integrated webcam into the Ubuntu VM.
   1. Make sure the virtual machine is not running and your webcam is not being used.
   2. Bring up the main VBox window and in the details tab for your virtual machine click USB.
   3. Make sure "Enable USB Controller" is selected. Also make sure that "Enable USB 2.0 (EHCI) Controller" is selected too.
   4. Click the "Add filter from device" button (the cable with the '+' icon).
   5. Select your device from the list.
   6. Now click OK and start your VM.
3. Open a terminal and execute the command ls /dev. You should now see video0 in the output. Note that you might need to add the camera manually from the top menu: Devices > Webcams > NameOfYourCamera
4. Install the tpk4128 module (with dependencies):

mkdir -p ~/tpk4128_ws/src
cd ~/tpk4128_ws/src
git clone https://github.com/tingelst/tpk4128-industrial-mechatronics.git
pip3 install ./tpk4128-industrial-mechatronics # Use pip for Python 2

5. Implement the Camera class in the file tpk4128/camera_opencv.py. See https://docs.opencv.org/3.4/dd/d43/tutorial_py_video_display.html for a tutorial on how to open a video stream from a webcam.
6. Implement the scripts/run_client_opencv.py script, that sends a message over localhost to a server implemented in the scripts/run_server_opencv.py script.
7. Open a new terminal and execute the run_server_opencv.py script.
8. Open a new terminal and execute the run_client_opencv.py script. You should now see a live stream from your webcam.
9. If time permits, work together in pairs and try to get the above system to work between two remote machines.
