ACKNOWLEDGEMENTS
To complete our graduation thesis, we would first like to express our sincere gratitude
to the lecturers of the Faculty of Electrical and Electronic Engineering at Ho Chi Minh
City University of Technology and Education. Throughout our academic journey, they
have provided us with valuable knowledge and d favorable conditions that laid a
solid foundation for us to apply to this project and future work.
We would especially like to extend our heartfelt thanks to our advisor, M.Eng. Le
Hoang Lam, for his dedicated guidance, insightful knowledge, and continuous support
during the process of conducting this thesis.
Due to limitations in time, knowledge, and experience, it is inevitable that our thesis
may contain shortcomings. We sincerely hope to receive constructive feedback and
guidance from the lecturers to further improve our work.
Once again, we would like to express our deep appreciation to everyone around usour families, loved one

model responds
quickly and relatively stably, the algorithm can be applied to many products and in many
other problems in industry. Although there are still some shortcomings related to the
mechanical structure, the team has tried to limit it to the lowest level.
Theoretically:
The team had an overall understanding and grasp of the operating principle and
position control theory of servo motors, learned more about the encoder theory, learned
how to communicate between modern devices such as cameras, QD75D4 position
control modules and PLCs. The team understands how to connect, wiring diagrams of
equipment and how to do mechanical processing.
About hardware:
The hardware is relatively rugged, withstanding the pressure when the system
operates at high frequency.
The structure is easy to disassemble, safe for the operator.
The electrical system is neatly connected, safe to use.
About the software:
The program is written in a complete way, easy for the operator.
pycharm software provides an easy working environment, .
The HMI simulation system can display speed and position parameters to help
monitor the operating status of the system more conveniently.
6.2. Development direction
- Enhance the mechanical structure to improve the overall precision of the system.
- Develop the model in a controlled environment where surrounding conditions
remain relatively stable.
- Upgrade the image processing unit to a more advanced processor to enhance the
recognition of complex objects and improve responsiveness to faster-moving items.
- Optimize the system to allow continuous conveyor operation while maintaining
reliable functionality.

76

- Expand object classification capabilities to support sorting of a wider variety of
items.
