Swimming soft millirobots to improve water quality monitoring in precision agriculture

Stuttgart – Digitalization is now an integral part of our daily lives and one of Europe’s biggest priority of the next decades: why don’t boosting the use of robotics also in the Agri-food sector? This is the aim of SOMIRO, the Horizon 2020 EU funded project started on January 1^st, 2021 that will develop and demonstrate the world’s first energy-autonomous swimming millirobot with immediate and major impact in the field of robotics and in precision agriculture. The research project, which will last 3 years, has received a contribution of about 3 million euros from the European Commission, it is coordinated by the Microsystem Technology Division of Uppsala University and it put together nine partners, from academia and industry, from six different European countries.

Metin Sitti, Director of the Physical Intelligence Department at the Max Planck Institute for Intelligent Systems, is one of the partners involved in the project. His role is leading the autonomous soft millirobot design, characterization, and testing. The main activities it will perform will be prototyping and testing magnetically actuated soft millirobots to design energy-efficient swimming propulsion using body undulation (i.e., traveling waves on the robot’s two side fins), characterizing the prototyped autonomous soft millirobot swimming performance, and using such characterization results to revise the robot design, actuation, and other functions to optimize the robot’s energy efficiency and navigation performance. The project kick-off will happen on January 21st and 22nd and the partners will kick off the activities planned for the first 6 months.

The SOMIRO project will develop a flat-worm-inspired mm-scale swimming robot with month-long energy autonomy, local intelligence, and the ability to continuously generate data and optically communicate. The project should demonstrate the potential for reducing the environmental impact of farming in terms of carbon footprint, eutrophication, and excessive use of pesticides and feed. These swimming robots would cover a much larger area than stationary systems and could be rapidly deployed and self-redistribute where most needed. They may serve as a stand-alone monitoring solution for indoor farming or complement drone-based remote sensing outdoors.

Until today, no energy-autonomous (with local intelligence and untethered) milli-robot has been demonstrated capable to withstand hours of continuous operation. The major reason is power limitation: locomotion requires much power and small robots have very limited energy storage and energy uptake. SOMIRO milli-robots will be less than 1 cm long and look like flatworms in the ocean. They should show that soft and stretchable systems require much less energy for movement than other robots of comparable size. To power, they will not rely on any dedicated infrastructure but only on natural sunlight.

SOMIRO soft milli-robots will be initially tested in two different types of water environment, an aquaponic system, and a paddy field, both located in Italy, but in the long-term, SOMIRO will be able to provide new tools for different areas of precision agriculture.
