Final Project — Responsive Kinetic Flower

Project Overview

This project focuses on the design and development of an interactive kinetic flower capable of opening and closing its petals in response to human presence. The system aims to simulate an organic behavior through a controlled mechanical transformation activated by electronic input.

The project integrates multiple domains of digital fabrication, including software design, 3D printing, and rapid prototyping using both additive manufacturing and low-fidelity materials such as cardboard. These processes were used iteratively to explore, test, and refine the geometry and functionality of the system.

From a mechanical perspective, the project is based on the transformation of motion, where a single input movement is distributed and translated into coordinated actions across multiple elements (petals). This required the development of a mechanism capable of converting rotational motion into vertical displacement, which then activates individual components in a controlled sequence.

The electronic system is built around a microcontroller platform (XIAO ESP32), integrating a PIR sensor as an input device and a servo motor as the output actuator. The system detects the presence of a user and triggers the mechanical response, creating a direct interaction between the environment and the object.

Beyond its technical implementation, the project explores the relationship between technology and perception. The goal is to move away from purely functional devices and instead create an artifact that evokes a sense of life, responsiveness, and subtle interaction, bridging the gap between engineered systems and natural behaviors.

Conceptual exploration

Motivation

The motivation behind this project is to explore how digital fabrication, mechanics, and electronics can be combined to create interactive objects that go beyond functionality and engage users at a sensory and emotional level.

Rather than designing a purely technical device, the intention is to develop a system that behaves in a responsive and organic way, where movement is not only controlled but also perceived as natural and expressive. The project uses a flower as a medium because it represents a familiar and intuitive form of transformation, allowing the interaction to be easily understood while still offering complexity in its mechanical resolution.

This project is also driven by an interest in translating simple electronic inputs into meaningful physical responses. The challenge lies in bridging the gap between detection (sensor), decision (microcontroller), and expression (mechanical movement), creating a coherent system where each layer contributes to the final experience.

References and Inspiration

The conceptual direction of this project is influenced by artists and studios that work at the intersection of art, technology, and human interaction. These references are relevant because the project is not intended to be just a mechanical object, but an interactive artifact capable of responding to human presence in a subtle and engaging way.

  • Refik Anadol — creates immersive environments using data and AI to generate emotional and sensory experiences through light, movement, and digital media.
  • Random International — their installation Rain Room responds to human presence, allowing visitors to influence the environment through movement.
  • Studio Roosegaarde — develops interactive installations that react to human behavior and environmental signals, combining technology, design, and public space.
  • Neri Oxman — explores the integration of biology, material systems, and computational design to create responsive structures and material-driven design.
  • teamLab — produces immersive digital environments where artworks react dynamically to visitor movement and presence.

At this stage, the exact mechanical solution is still under development. However, the direction of the project is clearly defined: to create a responsive kinetic artifact that merges art, design, and engineering through digital fabrication, generating a meaningful interaction between the user and the object.
