MIT’s tiny walking robot could eventually build other, bigger robots

Automated Assembly of a Walking Motor

A mobile motor created by a team at the Massachusetts Institute of Technology (MIT) could change the way we view and build robots.

The robot consists of five tiny fundamental parts that have the ability to assemble and disassemble into different functional devices — with the end goal of having it build other, larger robots.

MIT Professor Neil Gershenfeld, who was a part of this groundbreaking project, said that he based the concept of how all forms of life are made up of 20 amino acids.

“It’s a fundamentally different way in how you build robotics systems,” Gershenfeld told Digital Trends.

It’s groundbreaking in the sense that the new system is a step closer to creating a standardized set of parts that could be used to both assemble other robots and to adapt to a specific sets of tasks.

Through the use of a tiny kit of parts, Gershenfeld, along with MIT graduate student Will Langford, created a motor that replicates muscle movements such as walking. It also has more advanced abilities, like being able to turn a gear wheel. Gershenfeld calls these “micro-Lego parts.” The robot is strong: it can lift seven times its weight. Even with all these capabilities, the motor can reassemble itself as specific needs change or it tackles different tasks.

“Along with structural parts, Will is making tiny building blocks that contain even smaller integrated circuits,” Gershenfeld said.

Langford presented the work Wednesday at the International Conference on Manipulation, Automation and Robotics at Small Scales in Helsinki, Finland. 

“People have responded well at the conference,” Langford said. “In large part, it is thinking on a higher level than what a lot of other people are currently thinking in robotics. It adds a layer of abstraction.”

“People we have talked to have said it’s very liberating for the industry,” Gershenfeld added. 

Langford said that the ultimate goal of the project is for this type of motor to make more of itself. 

“Think of a 3D printer that can make electronics and robots…that’s very much where this is headed,” Gershenfeld said. 

Its impact on the robotics world could create a make it easier for people to design and build their own robots, even if they lack extensive engineering expertise.

“Because it is a direct right process, you don’t need advanced skills and a complex supply chain,” Gershenfeld said. “It will help make robotics accessible to people.”

Hit takers: The cutting-edge engineering making football helmets safer than ever
helmet engineering

Football helmets aren’t what they once were. And, while most of the time that turn of phrase is used to describe how things used to be better in the good old days, in this case, it’s certainly not.

Helmets are, in some senses, the most crucial bit of protective gear football players wear on the gridiron. Over the years, they’ve evolved from the leatherhead shell of yore to take advantage of breakthroughs on the material science front. Today’s big four helmet makers include the legacy brands Schutt and Riddell, in addition to comparative newcomers like VICIS and Xenith.

Scientists use a novel ink to 3D print ‘bone’ with living cells

The term 3D bioprinting refers to the use of 3D printing technology to fabricate biomedical parts that, eventually, could be used to create replacement organs or other body parts as required. While we’re not at that point just yet, a number of big advances have been made toward this dream over the past couple of decades.

When 3D printing went mainstream in the mid-2010s and exploded in popularity, it was about as hyped up as it possibly could be. Evangelists told us it would fundamentally transform the way goods were made, and usher in a bold new era of creative freedom. Soon, they said, we’d be able to fabricate anything we wanted on-demand, Star Trek replicator style, right from the comfort of our own homes.

But of course, 3D printing didn't really live up to that high-flying dream. Instead, it made a momentary splash and then largely returned to the fringes, gaining adoption in hobbyist workshops and cutting-edge product design labs, but not really changing the face of manufacturing in the way many hoped it might.
