In the era of Industry 4.0, where technology is increasingly penetrating every field, robots are no longer just supporting production but have begun to enter the world of art. The research “Interactive and Piano Player Robot” by the author fromUniversity of Economics Ho Chi Minh City (UEH) is not only a scientific work but also a combination of automation technology and performing arts. This robot can play music with high precision and convey emotions through facial expressions, creating a completely new musical experience where technology and emotions intersect.

In the context of the 4.0 industrial revolution taking place strongly, robots are no longer emotionless machines that only know how to perform simple production tasks. They are moving deeper into fields that require creativity and emotion like art. However, the biggest challenge is how a machine can convey emotions that previously only humans could express. This is the goal of the study “Interactive and Piano Playing Robot”. This project is not simply to program a robot to perform music; rather, it aims to create a robot that can interact with the audience and convey their emotions through facial expressions, thereby bringing a new and vivid artistic experience. This research aims to affirm that technology can surpass the boundaries of conventional machines, getting closer to the world of emotions and art.
The UEH’s research focuses on developing a robot that can play the piano and interact emotionally with the audience, a major step in the fields of automation and art. The main objectives include:
Kinematic and Dynamic Design: Analysis and simulations are carried out to ensure that the robot can play music with high precision. This includes optimizing the finger trajectories and the robotic hand structure to ensure that they can perform the movements with the required speed and precision. Advanced technological solutions will be applied to ensure that the robot is not just a mechanical machine but can perform the operations smoothly and vividly.
Facial Expressions: One highlight of this research is the robot’s ability to express emotions through its face. The team developed mechanical systems and software that would allow the robot to express emotions listed as happiness, sadness, and concentration, thereby creating an emotional connection with the audience. This transforms the robot from a music machine into a real performer capable of interacting with humans on a whole new level.
Control System Integration: The research focuses on integrating the control system for the robot. This system used microcontrollers and advanced control algorithms to synchronize musical playing and facial expressions. The goal was to ensure that the robot could respond immediately to input signals and perform musical pieces with the highest flexibility, providing a perfect performance experience for the audience.
The piano-playing robot is not only a technological achievement but also a bridge between technology and art, in which human intelligence and emotion are blended. This combination opens up new applications in the field of entertainment and lays the foundation for innovative technology products contributing to bringing industry 4.0 to a new level. In the future, robots will be no longer supportive tools but can become real artists bringing new and attractive experiences to people. This research is meaningful to the robotics industry, which opens new doors for performing arts, where technology and emotion can coexist and develop.
