Software Tools

We develop software tools for desigining origami and constrained form. The tools are freely available on the web.

What we do

In our lab, we try to understand the relationship between spatial forms and function through geometric modeling and algorithms to create novel kinematic and functional systems. Two main themes are origami, the behaviors that accompany surface folding, and structural tessellation, the geometry of modular systems with consistent spatial connections. Potential outputs of structural origami and tessellations include deployable and repeatedly foldable temporary structures, functional and reprogrammable cellular materials, and control devices for light, heat, or sound. We are interested both in understanding and creating phenomena. Topics of research include the following.

See Research Projects for actual projects.


Information for students

Tachi lab belongs to two departments. So you can join the lab from either departments. Note that the admission processes are very different. PLEASE CONTACT Tachi beforehand if you intend to apply.


We do not accept research student (Kenkyusei) (exception: MEXT scholarship students)
