Generative 3D Modeling for Soft-Robotics
This internship proposal concerns students from second year of master degree, interested in a research internship. The main goal of the internship to develop a prototype of an interactive modeling tool to ease the design of soft-robots. The tool will rely on framework on generative implicit surfaces and distance field.
Key Words : distance field modeling, implicit modeling, mechanical simulation, robotics.
The DEFROST team works on deformable robots. A deformable robot is composed of deformable structures, which behaves by deforming. Their design is often inspired by the mechanical properties of living organisms [Kim et al 2013]. These deformable robots have the advantage of being inexpensive to manufacture, robust and less dangerous in the context of interaction with humans. This new branch of robotics opens many prospects of applications.
In our research we developed a simulation platform SOFA [Faure et al 2012] that allows us to simulate and visualize, in real-time, the physical behavior of soft-material. Designing soft-robots is challenging as their shapes tend to be more and more complexes. The traditional modeling techniques based on surface meshes are limited in their ability to represent efficiently highly volumetric shapes.
This is why we are investigating new approaches to modeling as are generative implicit surfaces and distance field modeling.

– use of existing 3D modeling tools (blender, 3dsmax, catia, rhino,…)
– applied Mathematics or physical modeling: Linear Algebra, FEM, 3D modeling
– State on the art on modeling with distance field
– Prototype implementation in 2D
– Prototype implementation in 3D
