"Terradynamics" could help predict how robots move on granular media

March 22, 2013 8:18 am | News | Comments

Using a combination of theory and experiment, researchers have developed a new approach for understanding and predicting how small-legged robots move on and interact with complex granular materials such as sand. The research could help create and advance the field of "terradynamics"—a name the researchers have given to the science of legged animals and vehicles moving on granular and other complex surfaces.

Robot meets world

March 22, 2013 7:54 am | by Larry Hardesty, MIT News Office | News | Comments

When a robot is moving one of its limbs through free space, its behavior is well described by a few simple equations. But as soon as it strikes something solid, those equations break down. Roboticists typically use ad hoc control strategies to negotiate collisions and then revert to their rigorous mathematical models when the robot begins to move again. Researchers at Massachusetts Institute of Technology are hoping to change that, with a new mathematical framework that unifies the analysis of both collisions and movement through free space.

MIT “cheetah” robot rivals running animals in efficiency

March 11, 2013 10:28 am | by Jennifer Chu, MIT News Office | News | Comments

A 70-pound “cheetah” robot designed by Massachusetts Institute of Technology researchers may soon outpace its animal counterparts in running efficiency: In treadmill tests, the researchers have found that the robot, which is about the size and weight of an actual cheetah, wastes very little energy as it trots continuously for up to an hour and a half at 5 mph. The key to the robot’s streamlined stride can be found in the shoulders.

Yeti helps conquer “abominable” polar hazards

March 4, 2013 2:45 pm | News | Comments

A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers funded by the National Science Foundation have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains. Deployment of the robot—dubbed Yeti—could make Arctic and Antarctic explorations safer by revealing unseen fissures buried beneath ice and snow that could potentially claim human lives and expensive equipment.

Teaching robots lateral thinking

February 25, 2013 9:12 am | by Larry Hardesty, MIT News Office | News | Comments

Many commercial robotic arms perform what roboticists call "pick-and-place" tasks: The arm picks up an object in one location and places it in another. Usually, the objects are positioned so that the arm can easily grasp them; the appendage that does the grasping may even be tailored to the objects' shape. General-purpose household robots, however, would have to be able to manipulate objects of any shape, left in any location. And today, commercially available robots don't have anything like the dexterity of the human hand. Until now.

Lessons from cockroaches could inform robotics

February 22, 2013 1:12 pm | News | Comments

Running cockroaches start to recover from being shoved sideways before their dawdling nervous system kicks in to tell their legs what to do, researchers have found. These new insights on how biological systems stabilize could one day help engineers design steadier robots and improve doctors' understanding of human gait abnormalities.

Insect drives robot to track down smells

February 6, 2013 10:31 am | News | Comments

A small, two-wheeled robot has been driven by a male silkmoth to track down the sex pheromone usually given off by a female mate. The robot has been used to characterize the silkmoth’s tracking behaviors and it is hoped that these can be applied to other autonomous robots so they can track down smells, and the subsequent sources, of environmental spills and leaks when fitted with highly sensitive sensors.

Pentagon researches new life for dead satellites

January 23, 2013 10:42 am | by Alicia Chang, AP Science Writer | News | Comments

When satellites retire, certain parts—such as antennas and solar panels—often still work. There's currently no routine effort to salvage and reuse satellite parts once they're launched into space.  The Defense Advanced Research Projects Agency is spending $180 million to test technologies that could scavenge defunct communication satellites for their valuable parts and recycle them to build brand new ones for cheap.

Eavesdropping on the hidden lives of microbes

The robotic equivalent of a Swiss army knife

December 3, 2012 9:23 am | by David L. Chandler, MIT News Office | News | Comments

The device doesn't look like much: a caterpillar-sized assembly of metal rings and strips resembling something you might find buried in a home-workshop drawer. But the technology behind it, and the long-range possibilities it represents, are quite remarkable. The little device is called a milli-motein, a name melding its millimeter-sized components and a motorized design inspired by proteins, which naturally fold themselves into complex shapes. The robot may be a harbinger of future devices that could fold themselves up into almost any shape imaginable.

Researchers aim to create 'MacGyver' robot

October 9, 2012 11:47 am | News | Comments

Robots are increasingly being used in place of humans to explore hazardous and difficult-to-access environments, but they aren't yet able to interact with their environments as well as humans. If today's most sophisticated robot was trapped in a burning room by a jammed door, it would probably not know how to locate and use objects in the room to climb over any debris, pry open the door, and escape the building.
