SODA

Problem

Traditional utensils, such as forks and spoons, are hard and stiff, causing discomfort and fear among users, especially when operated by autonomous robotic arms. Additionally, these systems require frequent utensil changes to handle different food types.

Design Process

Our design aim to avoid hard and sharp edges, making the utensil safe  and comfortable for users. Additionally, it aims to combine the functionalities of forking and spooning into a single utensil, ensuring versatility and efficiency in handling various food types. 

​

Thus, we found another interesting structure which has huge potential. That is the Origami-inspired artificial muscles. We use 3D printing to print the origami structure. And the outside is a simple material ---- Ziplog. When it starts to vacuum, the structure starts to fold as the creases that the material already have as the picture shows. And the creases on SODA will become a Multi-purpose utensil capable of gripping and scooping solid and liquid food.

Final Product

SODA advances the field of robot-assisted feeding by integrating fluid-driven artificial muscles into a new type of utensils, we achieve a combination of softness, adaptability, and cost-effectiveness, addressing key user needs and preferences. The innovative design leverages the flexibility and simplicity of origami structures, providing a safer and more efficient tool for individuals with motor impairments. This approach not only enhances the interaction between the user and the robot but also simplifies the manufacturing process, making the system more accessible and practical for everyday use.
