'Squishy' motors and wheels give
soft robots a new ride
Rutgers engineers, in a
breakthrough, create a soft motor that could power versatile soft robots

Summary:
A small, squishy vehicle equipped with soft wheels rolls over
rough terrain and runs under water. Future versions of the versatile vehicle
might be suitable for search and rescue missions after disasters, deep space
and planet exploration, and manipulating objects during magnetic resonance
imaging (MRI), according to its creators. Their most important innovation is a
soft motor that provides torque without bending or extending its housing.

A small, squishy vehicle equipped with
soft wheels rolls over rough terrain and runs under water.
Future versions of the versatile vehicle might be suitable for search and
rescue missions after disasters, deep space and planet exploration, and
manipulating objects during magnetic resonance imaging (MRI), according to its
creators at Rutgers University.
Their most important innovation is a soft motor that provides torque
without bending or extending its housing, said Aaron D. Mazzeo, assistant
professor in the Department of Mechanical and Aerospace Engineering, who
coauthored the study.
The Rutgers engineers' breakthrough study was published online this week in
the journal Advanced Materials. The lead author is Xiangyu Gong,
who earned a master's degree in mechanical engineering at Rutgers in 2015 and
is now a doctoral student at Rensselaer Polytechnic Institute in Troy, New
York. Aside from Gong and Mazzeo, other authors include current or former
Rutgers students Ke Yang, Jingjin Xie, Yanjun Wang, Parth Kulkarni and Alex Hobbs.
"The introduction of a wheel and axle assembly in soft robotics should
enable vast improvement in the manipulation and mobility of devices,"
Mazzeo said. "We would very much like to continue developing soft motors
for future applications, and develop the science to understand the requirements
that improve their performance."
According to Mazzeo, innovations by Gong and the other Rutgers researchers
include:
- Motor rotation without bending. "It's
actually remarkably simple, but providing torque without bending is
something we believe will be advantageous for soft robots going
forward," Mazzeo said.
- A unique wheel and axle configuration that is not
found in nature. The soft wheels may allow for passive suspensions in
wheeled vehicles.
- Wheels that use peristalsis, the process people
use to push food to the stomach through the esophagus.
- A consolidated wheel and motor with an integrated
"transmission."
- Soft, metal-free motors suitable for harsh
environments with electromagnetic fields.
- The ability to handle impacts. The vehicle
survived a fall eight times its height.
- The ability to brake motors and hold them in a
fixed position without the need for extra power.
To create the vehicle, the Rutgers engineers used silicone rubber that is
nearly 1 million times softer than aluminum, Mazzeo said. Its softness is
somewhere between a silicone spatula and a relaxed human calf muscle.
The motors were made using 3-D printed molds and soft lithography, and a
provisional patent has been filed with the U.S. government.
"If you build a robot or vehicle with hard components, you have to
have many sophisticated joints so the whole body can handle complex or rocky
terrain," Gong said. "For us, the whole design is very simple, but it
works very well because the whole body is soft and can negotiate complex
terrain."
Future possibilities include amphibious vehicles that could traverse rugged
lakebeds; search and rescue missions in extreme environments and varied
terrains, such as irregular tunnels; shock-absorbing vehicles that could be
used as landers equipped with parachutes; and elbow-like systems with limbs on
either side.
"We think these robots also would be useful for working around
children or animals, and you could envision them being helpful in
hospitals," Mazzeo said. "There are opportunities also for toys and
for creating educational science or engineering kits."
Funding for the project was provided by the Rutgers School of Engineering,
the Department of Mechanical and Aerospace Engineering, the University Research
Council and an A. Walter Tyson Assistant Professorship Award.
