Muscle-mimicking soft robots may help rehabilitate stroke victims
When
we think of robots, we tend to think of big, industrial, metal
machines. These may be ideal for tasks like manufacturing but they don’t
do well when a gentler touch is needed. That’s where soft robots come
in. These squishy, light, and flexible machines are generally safer and
more compliant, making them perfect for situations that require close
contact with humans and adaptability.
A
team of researchers at École Polytechnique Fédérale de
Lausanne’s Reconfigurable Robotics Lab (RRL) is hard at work developing
an array of soft robots that may help in tasks like rehabilitation, home
care, and search and rescue.
“Our robot designs focus largely on safety,” Jamie Paik, the director of the RRL, said in a press release. “There’s very little risk of getting hurt if you’re wearing an exoskeleton made up of soft materials, for example.”
The
soft robots developed at RRL are designed to mimic human muscles, using
actuators for movement, and elastomers like silicon and rubber to make
them soft to the touch. In simulations, the robots have been shown
to stretch up to six times their initial length and bend in two
directions.
In
the real world, the researchers have used their soft robots to create
medical devices such as a wearable belts to help stroke patients
maintain good posture and movement during rehabilitation exercises. The
prototype device needs to be connected to external pumps but, in the
future, the engineers hope to scale the system down to fit right on the
belt.
“We
are working with physical therapists from the University Hospital of
Lausanne (CHUV) who are treating stroke victims,” said Matthew
Robertson, the researcher in charge of the project. “The belt is
designed to support the patient’s torso and restore some of the person’s
motor sensitivity.”
Since
they can be squeezed and crushed but still maintain their shape, soft
robots are also being considered for tasks that require navigating tight
spaces, such as searching through rubble after natural disasters.
