Unmanned Surface Vehicle - USV is known as a modern vehicle which assists people in discovering water environment. It can either be remotely controlled or operate automatically to fulfill different tasks.
UNMANNED SURFACE VEHICLE (USV)
Nowadays, USV is used all around the world in a variety of fields such as:
AHRS (Attitude and Heading Reference System) is an estimate of the angles of roll, pitch, yaw of self-propelled robots with high accuracy and updating speed. Using AHRS and accelerometer sensors, Inertial Navigation System (INS) is able to locate the robot with high accuracy at the beginning but the INS drift is greater with time.Combining Global Positioning System (GPS) with INS system increases the quality in many aspects such as accuracy, speed update, ...

ROV is an underwater vehicle remotely controlled by cables and thrusters, varied in shape and size. ROV is regarded as a modern tool that enables people to explore the underwater world, perform many tasks at depths that humans can not reach. It can work under water for long periods, in harsh environment. Often there is a video camera, carrying sensors and hand-held machines, serving a variety of tasks for military and civil purposes.
The AUV can be considered as an improved version of the ROV, which is a highly autonomous unmanned vehicle for underwater applications.Mostly of the torpedo type with propulsion and steering, self-controlled.Can work under water for long periods of time, depending on the source of energy.AUV is equipped with sensor devices, serving a variety of tasks for military and civil purposes.
The need for robots is increasing in complex manufacturing processes that contribute to increased productivity, reduced costs, improved quality and accuracy, and reduced risk when people work at dangerous environment.The design of robotic systems operating without human intervention is becoming more and more popular, especially in the era of rapid development of computer vision today.

Temperature control and level control are widely concerned nowadays, especially in industry and agriculture. In the factories that specialize in producing chemical and beverage, the requirements concerning liquid’s temperature and volume (or level) are very strict. Therefore, researching a appropriate solution for this problem would be a tremendous help to quality management as well as production optimization.
Our model consists of a controlling tank and a storage tank. After being pumped into the controlling tank, the liquid is periodically heated using heater resistor. A pump is controlled by PLC and inverter to pump the required amount of liquid into the storage tank. The model also uses a PID controller to control the tank temperature. Additionally, the model is equipped with HMI interface, SCADA interface, LAN based web server, IOT-intergrated database to supervise the system
Our filling model is built based on the design of the filling systems used in beverage, chemical factories,...
Operation: A bottle is brought into the system and carried along the conveyor -> the sensors detect the bottle and stop the conveyor -> the system fills the bottle with water from the storage tank -> the amount of water is measured by a flow sensor -> when the bottle is full, the system stop pumping out water, the conveyor moves again and a new filling process begin

The classification of products according to the characteristics of the products is very popular in the industry such as classification of substandard products, according to color, height, ... so that products with similar characteristics can be arranged. In this model, the material and height characteristics are used to classify products.
Operating procedure: The product is put on the conveyor belt -> the height sensor will measure the height -> the metal sensor will recognize whether the material is metal -> If it is metal and set the height, the cylinder will push then the product will pick up the product tray into the hands on the second floor warehouse (store has 2 floors: 1st floor: nonmetals, 2nd floor: metal) -> If the product is metal but not the correct height, the product will go out of the conveyor -> non-metallic sensor -> If the product is non-metal and the correct height, the cylinder pushes the product to the tray and then the picker takes the product away

Augmented reality (AR) is the integration of information from a computer into a real-world environment, in which the insertion of images into the user's vision is dominant. AR technology improves the worker's ability to increase productivity, it provides a safe environment and enhances job satisfaction of workers.
Application of AR:
