Soft robots controlled by an external magnetic field are capable of performing movement and manipulation tasks effectively thanks to their ability to undergo programmed deformations, which in turn opens up access to hard-to-reach areas of the human body and expands the possibilities for minimally invasive medical interventions. Despite the potential of such systems, most existing solutions are based on the use of elastomeric materials, whose mechanical properties limit the degree of their deformation, reducing their effectiveness in confined spaces and fixing their functionality at the design stage without the possibility of adaptation during operation.
This project has developed a control system for ferrofluid droplets that function as programmable magnetic soft robots. Using programmable electromagnets, the system allows temporary adjustment of external magnetic fields. This enables the movement of droplets through narrow channels, their separation and merging for targeted delivery of liquid cargo, as well as dynamic reconfiguration for precise manipulation of delicate objects. The behavior of ferrofluid droplets was also studied under magnetic attraction, which allowed their behavior in response to changes in magnetic fields to be recorded. This approach demonstrates significant potential for application in confined spaces, including biomedical devices and spacecraft, where autonomy is critical to the success of long-duration space missions.
