1) What is the difference between Internet of Things and Industrial Internet of Things?
Internet of Things (IoT) connects general devices to the internet, while Industrial Internet of Things (IIoT) focuses on industrial applications, emphasizing operational efficiency and smart manufacturing.
2) Write down the difference between Industry 3.0 and Industry 4.0?
Industry 3.0 is characterized by computer automation, while Industry 4.0 integrates cyber-physical systems, IoT, and smart automation.
3) Write down two Industry 4.0 related technologies and explain their main role in Industry 4.0?
Artificial Intelligence (AI) enables data-driven decision-making, and IoT facilitates device connectivity and real-time communication
4) Is a chair a Thing? Write down at least two applications of a Smart Chair.
A chair is not inherently a Thing unless equipped with sensors or connectivity. Applications of a smart chair include posture monitoring and smart office integration for productivity.
5) Write down the names of two of the most widespread and commonly used IoT application protocols?
MQTT and CoAP are two widespread IoT application protocols.
6) Draw four layers of IoT and write the names of each layer?
The four layers are Sensors, Network, IoT Platform, and Application.
7) Name the four terminologies used in tracking and wayfinding?
Positioning, Fingerprinting, Tracking, and Proximity.
8) RSSI-based positioning is often unreliable due to the drops of the signal level by at least 75% if we
double the distance between the object and the network node. Give at least one solution to enhance
the accuracy in an RSSI-based positioning system?
Triangulation or integrating additional sensor data can improve accuracy in RSSI-based positioning.
9) Write down at least four tracking technologies for indoor use cases.
1. RFID (Radio-Frequency Identification), 2. BLE (Bluetooth Low Energy) , 3. UWB (Ultra-Wideband), and 4. Wi-Fi (Wireless Fidelity).
10) What is an industrial robot and what are its advantages?
An industrial robot is a programmable device for automation, improving productivity, safety, and precision.
11) What is an industrial robot cell? And what is an industrial robot line?
A robot cell is a workspace with one or more robots and safety measures. A robot line is a sequence of robot cells working together, like in an assembly line.
12) Give an example of an industrial robot cell and an industrial robot line.
Robot cell: welding robot with safety enclosure. Robot line: car assembly line robots.
13) What is the largest size of a CAN packet and what is bit-stuffing?
The largest size of a CAN packet is 8 bytes. Bit-stuffing involves inserting non-informative bits to maintain synchronization.
14) Twisted pair wires are often used for CAN networking. Describe which layers CAN standards work in an OSI network model.
CAN operates on the Data Link and Physical layers.
15) What is CAN and which industries use CAN?
CAN (Controller Area Network) is used for real-time communication in industries like automotive, manufacturing, and healthcare.
