Incredibly Mobile “Minimalist Robot” Could Be the Future of Non-Invasive Medicine
Lou Del Bello, 28-Jan-2018

In Brief
Researchers invented a tiny "minimalist robot" that looks like a caterpillar and can perform a wide range of movements, including jumping, crawling through tunnels, and climbing out of a pool. It is designed to deliver drugs to specific targets in the human body.


Restless Robot
A new, tiny, “minimalist robot” can achieve a complex series of movements that should one day allow it to patrol the human body from the inside, according to researchers at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, who describe their work in a Nature paper.

Not only does the caterpillar-inspired robot walk, but it also crawls, jumps, and even swims — moving seamlessly from a wet environment to a dry one as it climbs out of a pool.

The researchers who created the plyable millirobot, which is about the same size as a grain of rice, were inspired by soft-bodied beetle larvae and caterpillars. Jellyfishes also lent some of their features to the little creature.

But how does this elastic robot achieve such a variety of movements if it doesn’t have any sort of limbs? The German researchers used external magnetic fields to put pressure on magnetic particles within its body, changing its shape. It’s this deformation, the engineers say, that allows the robot to jump over obstacles, crawl through tunnels, and more.

Non-Invasive Medicine
Such abilities will be put to the test once the minimalist robot is ready to move inside the human body and deliver drugs to targets that are otherwise difficult to reach without surgery. In order to do that, the tiny bot is also able to pick an object up, move it, and release it.

“In the future, our robot can carry drugs and deliver them to a desired location where they are most needed, much like a doorstep delivery,” author and Physical Intelligence Department director Metin Sitti said in a press release. “We would use it for minimally invasive medical applications inside the human body: it would be delivered through swallowing or a cavity on the skin and make its way through the digestive or urinary tract, abdominal cavity, or heart surface.”

To date, the robotic caterpillar has been only tested in an artificial stomach model and chicken tissue. But one day, the researchers hope, it could become a standard tool in healthcare.
