What are the different capabilities, limitations and applications of the current iterations of 3D printing equipment materials and technologies?

Insect mating behavior has lessons for drones

June 1, 2015 7:36 am | by Univ. of California, Riverside | News | Comments

Male moths locate females by navigating along the latter's pheromone (odor) plume, often flying hundreds of meters to do so. Two strategies are involved to accomplish this: males must find the outer envelope of the pheromone plume, and then head upwind. Can understanding such insect behavior be useful for robotics research?

Cheetah robot lands the running jump

May 29, 2015 10:56 am | by Jennifer Chu, MIT News Office | Videos | Comments

In a leap for robot development, the Massachusetts Institute of Technology researchers who built a robotic cheetah have now trained it to see and jump over hurdles as it runs, making this the first four-legged robot to run and jump over obstacles autonomously. To get a running jump, the robot plans out its path, much like a human runner: As it detects an approaching obstacle, it estimates that object’s height and distance.

Helping robots put it all together

May 27, 2015 9:28 am | by Larry Hardesty, MIT News Office | Videos | Comments

Today’s industrial robots are remarkably efficient, as long as they’re in a controlled environment where everything is exactly where they expect it to be. But put them in an unfamiliar setting, where they have to think for themselves, and their efficiency plummets. And the difficulty of on-the-fly motion planning increases exponentially with the number of robots involved.

Robot masters new skills through trial-and-error

May 22, 2015 10:04 am | by Sarah Yang, Univ. of California, Berkeley | Videos | Comments

Univ. of California, Berkeley researchers have developed algorithms that enable robots to learn motor tasks through trial and error using a process that more closely approximates the way humans learn, marking a major milestone in the field of artificial intelligence. They demonstrated their technique, a type of reinforcement learning, by having a robot complete various tasks without pre-programmed details about its surroundings.

How to make continuous rolls of graphene

May 21, 2015 7:30 am | by David L. Chandler, MIT News Office | News | Comments

Graphene is a material with a host of potential applications, including in flexible light sources, solar panels that could be integrated into windows and membranes to desalinate and purify water. But all these possible uses face the same big hurdle: the need for a scalable and cost-effective method for continuous manufacturing of graphene films.

Seashell strength inspires stress tests

May 20, 2015 7:43 am | by Mike Williams, Rice Univ. | News | Comments

Mollusks got it right. They have soft innards, but their complex exteriors are engineered to protect them in harsh conditions. Engineers at the Indian Institute of Science and Rice Univ. are beginning to understand why. By modeling the average mollusk’s mobile habitat, they are learning how shells stand up to extraordinary pressures at the bottom of the sea.

Laser technique for self-assembly of nanostructures

Researchers from Swinburne Univ. of Technology and the Univ. of Science and Technology of China have developed a low-cost technique that holds promise for a range of scientific and technological applications. They have combined laser printing and capillary force to build complex, self-assembling microstructures using a technique called laser printing capillary-assisted self-assembly (LPCS).

First large-scale graphene fabrication

May 14, 2015 4:32 pm | by Ron Walli, Oak Ridge National Laboratory | News | Comments

One of the barriers to using graphene at a commercial scale could be overcome using a method demonstrated by researchers at Oak Ridge National Laboratory. Graphene, a material stronger and stiffer than carbon fiber, has enormous commercial potential but has been impractical to employ on a large scale, with researchers limited to using small flakes of the material.

A new way to manufacture nanofibers

May 13, 2015 8:51 am | by James Hataway, Univ. of Georgia | Videos | Comments

Researchers at the Univ. of Georgia have developed an inexpensive way to manufacture extraordinarily thin polymer strings commonly known as nanofibers. These polymers can be made from natural materials like proteins or from human-made substances to make plastic, rubber or fiber, including biodegradable materials.

Controlling swarms of robots with a finger

May 13, 2015 8:05 am | by Jason Maderer, Georgia Institute of Technology | Videos | Comments

Using a smart tablet and a red beam of light, Georgia Institute of Technology researchers have created a system that allows people to control a fleet of robots with the swipe of a finger. A person taps the tablet to control where the beam of light appears on a floor. The swarm robots then roll toward the illumination, constantly communicating with each other and deciding how to evenly cover the lit area.

Pet robotics has come a long way from the Tamagotchi craze of the mid-90s. In Japan, people are becoming so attached to their robot dogs that they hold funerals for them when the circuits die.

Robot pets to rise in an overpopulated, tech-crazed world

May 12, 2015 11:04 am | by University of Melbourne | News | Comments

Robotic dogs are likely to replace the real thing in households worldwide in as little as a decade, as our infatuation with technology grows and more people migrate to high-density city living. University of Melbourne animal welfare researcher Dr. Jean-Loup Rault says the prospect of robopets and virtual pets is not as far-fetched as we may think.

Toward a squishier robot

May 5, 2015 11:37 am | by Univ. of Pittsburgh | News | Comments

For decades, robots have advanced the efficiency of human activity. Typically, however, robots are formed from bulky, stiff materials and require connections to external power sources; these features limit their dexterity and mobility. But what if a new material would allow for development of a "soft robot" that could reconfigure its own shape and move using its own internally generated power?
