Reference:
or this assignment, the devices that I used were servo motors and ultrasonic sensors. The distance sensor would allow movement of the servo motor. When a person moves closer to sensor, it would detect some movement and allow it to move. I was a bit uncertain with the whole concept of my idea, but my idea was to initially show that once a person goes close to a sensor, the movement would stop, and the clothes would go to its original position. This fabric is supposed to move on its own when servo moves, I thought that adding string attached to the main fabric would allow other fabrics to move. IT worked, but the movement was too fast. The feedback that I got was the “Delay” function was the main issue since I wanted the servo to move slowly. Perhaps I could improve by making sure the servo was coded well.
It was my first try with the sewing method, so since Galina taught us that a little bit, I had the privilege of getting my own sewing machine from home. With some fabrics I took from Product design room, I used that for sampling and incorporated certain floral designs in my project. I am happy to know that I picked up sewing skills pretty fast.
