Expressive Motion

Concept Description

For this assignment, I created a project called Perseverance. The concept represents a young man training to become a samurai. His posture is firm and focused, and his only objective is the training post in front of him. Through continuous practice and repetition, he aims to master his skill. The deeper idea behind the project is that perseverance through discipline not only builds strength but also cultivates inner peace.

In the starting state, everything is static. The warrior stands still, symbolizing preparation and mental focus. When the button is pressed once, the servo moves the arm and produces a single swing of the blade. This represents the beginning of effort. If the button remains pressed, the warrior continues swinging repeatedly, expressing long-term dedication and consistent practice. When the button is released, the motion stops and the system resets.

Technical Description

The movement is achieved using a servo motor connected at the arm joint. The laser-cut components consist of three separate pieces: the body of the warrior, the arm with the sword, and the training post. The Arduino reads the button input and controls the servo to create the swinging motion.

    train();

  } ;

  Serial.println(digitalRead(btnPin));

}

void train() {

  for (pos = 30; pos <= 150; pos += 2) {  

 

    myservo.write(pos);  

    delay(15);          

  }

  for (pos = 150; pos >= 30; pos -= 2) {  

    myservo.write(pos);                  

    delay(15);                            

  }
