[...] it would be interesting in surgery if you could swallow the surgeon. You put the mechanical surgeon inside the blood vessel and it goes into the heart and looks around.
[...] How do we make such a tiny mechanism? I leave that to you.
- Richard Feynman, There's plenty of room at the bottom, 1959.
We are developing a modular robotic system that can be swallowed and will assemble inside the G.I. Tract for therapeutic and diagnostic procedures. ETH Zürich is one of four European universities participating in this project, led by Paolo Dario at Scuola Superiore Sant'Anna.
My research involves the investigation of the self-assembly of the ARES robot inside the stomach. Using a specific magnet configuration on the connection face, assembly success rates of up to 90% are possible.
This project aims at developing magnetic microrobotics for ophtalmic surgery.
I am involved in developing the magnetic model for assembled-MEMS microrobots. The model is validated through FEM simulations and experiments, and captures the characteristics of complex 3-D structures. It allows us, for the first time, to consider full 6-DOF control of untethered devices.
