NAVIGATION
Introduction:
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, ...

OBJECT CLASSIFICATION SYSTEM
- Combining equipment in industrial automation such as cylinder, solenoid valve, conveyor, rotary handle, picking handle ... into the product classification model. Especially the picking mechanism is made of two axes X, Y is the visme attached to the stepper motor and the Z axis is the travel cylinder and the pick up cylinder.
- Using module motion controller of PLC S7-1200 to control position for two X and Y axis motors and one rotary platform.
- Use Matlab to capture and identify the chess pieces, then process and transmit PLC position parameters in x, y coordinates so that the station can position the chess piece to the desired position automatically.
- Monitor, read status and manual mode to control effects on remote devices via Webserver written on HTML, CSS, Jquery and Javascript.

MIXING TANK SYSTEM
Our mixing tank system demonstrates a simple mixing process: fetching constitutive colourants (red, blue, yellow) -> computing the amount of each colourants -> mixing and blending to produce a new batch of colourant -> canning finished product.
Feature:
- Direct control using HMI
- Remote supervisory control through the use of SCADA and WebServer

HEATING TANK
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 an 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-integrated database to supervise the system.
Under development:
- Combine with other systems to form a large-scale production line
- Integrate a chiller into the output pump,...
- Widen the controller’s temperature range to adapt to different kinds of industrial systems

FILLING 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
Feature:
- Direct control using HMI screen
- Remote supervisory control through the use of SCADA and WebServer
- Storage tank’s temperature can be controlled using PID controller
- IFM sensors with I/O Link communication
- Precisely controlled conveyor using RS-Servo
- Product classification system using camera

CLASSIFICATION AND STORING SYSTEM
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.
Feature:
- Control via HMI screen
- IFM sensors with IO-Link communication
- Stable Gripper
- Conveyor control with inverter
