Music is a language that transcends time, and performance is a precise art combining emotion and technology. Traditional instrumental performance demands precise control over dynamics, rhythm, and emotion, requiring complex muscle memory and artistic understanding. Today, through high-precision servo motors, advanced algorithms, and sensor fusion technology, robots can simulate this process, achieving astonishing automated performances. Our "Ancient Melodies of the Qin" playing robot is a prime example of this fusion of technology and art. This beautifully designed humanoid robot can not only independently perform a variety of pieces from classical to modern, but also interact with the audience through an intuitive interface. Every movement of its precise "fingers" on the keys or strings is calculated and controlled in milliseconds, reproducing the delicate dynamics of human performance, allowing the audience to appreciate beautiful melodies while witnessing the visual charm of precis
