What are Trajectoids?

Trajectoids are a new and exciting object type that can be 3D printed. Developed by researchers in South Korea, Trajectoids are shapes that, when rolled down a hill, follow a specific and complex trajectory. Unlike a cylindrical shape that rolls straight down a hill or a cone that curves predictably, Trajectoids generate unique and customizable paths. These objects open up new possibilities for 3D printing and provide a way to create intricate and dynamic designs.

Definition of Trajectoids

A Trajectoid is defined as a shape that, when rolled down a hill or inclined surface, follows a predetermined trajectory. This trajectory can be complex, consisting of loops, sharp corners, or any other desired path. The shape of the Trajectoid is designed in such a way that it interacts with the surface geometry to create the desired trajectory. By understanding the relationship between surface geometry and trajectory, researchers have been able to develop algorithms to generate these unique shapes.

How Trajectoids are Created

The creation of Trajectoids involves a two-step process. The first step is to establish a mathematical link between surface geometry and trajectory. Researchers needed to verify that there was a way to design a shape that could generate a specific trajectory when rolled down a hill. After confirming this link, the researchers proceeded to the second step: developing an algorithm to generate Trajectoid shapes based on a given trajectory.

Through extensive research and experimentation, the algorithm was refined and optimized to generate Trajectoids that accurately follow the desired paths. This process involves analyzing the trajectory requirements and mapping them onto the surface geometry of the object. By carefully manipulating the shape and structure of the object, researchers were able to achieve precise and intricate trajectories.

Linking Surface Geometry with Trajectories

The fundamental concept behind Trajectoids is the connection between surface geometry and trajectories. By understanding how the shape of an object interacts with the surface it rolls on, researchers can design complex and customizable trajectories. This link has been established mathematically, providing a solid foundation for the development of Trajectoids.

Through mathematical modeling and simulation, researchers were able to demonstrate the relationship between surface geometry and trajectory. By manipulating the shape and structure of the object, they were able to control and guide the path it takes when rolled down a hill. This understanding of how surface geometry influences trajectory is crucial for the development of Trajectoids and opens up new possibilities for creating dynamic and intricate designs.

The Research Process

The research process involved several key steps to develop and validate the concept of Trajectoids. These steps included verifying the mathematical link between surface geometry and trajectory, developing an algorithm to generate Trajectoid shapes, and testing the theory through 3D printing and experimentation.

Verifying Mathematical Way to Link Surface Geometry

The first step in the research process was to establish a mathematical way to link surface geometry with trajectory. Researchers needed to confirm that there was a relationship between the shape of an object and the path it would take when rolled down a hill. Through mathematical analysis and simulation, they were able to validate this link and demonstrate that it was indeed possible to design shapes that would produce specific and complex trajectories.

Developing an Algorithm to Generate Shapes

After confirming the mathematical link, researchers focused on developing an algorithm to generate Trajectoid shapes based on a given trajectory. This algorithm needed to take into account the desired trajectory, the surface geometry, and the constraints of 3D printing. Through iteration and refinement, the algorithm was optimized to generate shapes that accurately followed the desired paths.

Testing the Theory with 3D Printed Objects

Once the algorithm was developed, researchers tested their theory by 3D printing ball shapes generated by the algorithm. These ball shapes were designed to follow specific trajectories when rolled down a hill. By carefully controlling the shape and structure of the objects, researchers were able to observe the desired trajectories in action.

Experimental setups were created to ensure the accuracy and consistency of the trajectories. Ball bearings were inserted into the 3D printed Trajectoids to ensure proper rolling. This allowed researchers to validate their theory and demonstrate the functionality of Trajectoids in real-world scenarios.
