Data-Driven Modeling of Non-Rigid Bodies for Robotics
Dra. Ming C. Lin
University of North Carolina Chapel Hill. USA.
Non-rigid materials are widely used in medical robotics, design and manufacturing, virtual surgery for soft robot planning, procedural rehearsal and training, etc. Identification of mechanical properties, such as tissue elasticity parameters, is critical to enable medical robots to safely operate within highly unstructured, deformable human bodies and to compute desired, accurate force feedback for individualized haptic display characterized by patient-specific parameters. In addition to medical robots, simulations are also increasingly used for rapid prototyping of clinical devices, pre-operation planning of medical procedures, virtual training exercises for surgeons and supporting personnel, etc. And, bio-tissue elasticity properties are central to developing realistic and predictive simulation and for designing responsive, dexterous surgical manipulators. Furthermore, with increasing interest in 3D printing for rapid creation of soft robots consisting of flexible materials, the ability to easily acquire material properties from existing sensor data, such as medical images and videos, can help to replicate similar material properties. In this talk, I present recent advances to determine patient-specific tissue elastic parameters from images and videos, acceleration techniques, and application to medical applications. I conclude by discussing possible future directions and new challenges.

IEEE Distinguished Speaker
Breathing, running, eating, urinating, singing or giving birth are all actions that mobilize our ELASTICITY. Focusing on the concept of the “elastic human” is now a promising priority. The loss of elasticity causes the onset of numerous pathologies, or their worsening like cardiac insufficiency, ruptured aneurysm, emphysema, etc. Any oxidizing substance can attack elastic fibers and accelerate their deterioration. UV rays, cigarettes, pollution (certain nanoparticles in particular) and a poor diet are some of the main toxic agents. Less well known is what some call «caramelization» of the body, due to excess sugar (notably in the context of diabetes). Aging is not the only factor involved in our organs and tissues losing their mechanical properties. Indeed, some genetic syndromes induce a weakness of elasticity or viscoelasticity. In order to make up for mechanically failing tissues in humans, it is also possible to implant biomaterials. The production of biomimetic materials, which imitate nature by taking inspiration from its shapes and materials, is now being envisaged. The co cultivation of smooth muscle cell and endothelial cell layers to construct in vivo-like vasculature has already been developed, and studies are underway to integrate it in biomaterials, or even enable its 3D printing.
