Intelligent micro-robots can “transform” with their surro

Introduction: According to a recent report by the US Daily Science website, scientists from the EPFL and the Federal Institute of Technology in Zurich have jointly developed a miniature flexible robot that can change shape according to the surrounding environment. In the future, this robot can be swallowed by us to deliver the drug directly to the lesion tissue.

According to a recent report by the US Daily Science website, scientists from the EPFL and the Federal Institute of Technology in Zurich have jointly developed a miniature flexible robot that can change shape according to the surrounding environment. In the future, this robot can be swallowed by us to deliver the drug directly to the lesion tissue.

There are many microbes that have changed with the environment, and the team of scientists led by EPFL's Selman Sakar and Bradley Nielsen of the Federal Institute of Technology in Zurich drew inspiration and designed it. This highly flexible, biocompatible miniature intelligent robot.

These devices can swim through fluids and change shape when needed, so they can travel through narrow blood vessels and complex systems without affecting speed or maneuverability. In addition, they are made of hydrogel nanocomposites containing magnetic nanoparticles, so they can be controlled by electromagnetic fields.

The challenges of manufacturing micro-robots have been solved by scientists using an origami-based folding approach. Sakar explains: "Our robots have a special composition and structure that allows them to adapt to the characteristics of the fluid. For example, if they encounter changes in viscosity or osmotic concentration, they change their shape, maintaining speed and mobility. At the same time, there is no loss of control over the direction of motion."

It is reported that these deformations can be achieved by pre-programming to maximize performance without the use of bulky sensors or actuators. Chemical. The robot can use electromagnetic field control or use fluid flow to pass itself through the cavity. Either way, they automatically deform into the most appropriate shape.

In addition to being more efficient, the manufacturing costs of these miniature soft robots are also reasonable. Currently, the research team is working to improve the ability of robots to swim through complex fluids, such as complex fluids in the human body.
