A robotic sensor that won an R&D 100 Award in 2009 has been put to use by Woods Hole Oceanographic Institution (WHOI) in Gulf of Maine coastal waters to monitor the way red tides behave. These harmful algal blooms, which generate a potentially fatal toxin, can be a challenge to track or predict. The Environmental Sample Processors have been remotely deployed and should simplify and enhance this effort.

Germany's defense minister on Wednesday admitted mistakes were made in the handling of a program to develop unmanned surveillance drones and announced tougher oversight procedures for all armament projects. Opposition parties say Thomas de Maiziere wasted public funds by canceling the botched 600 million euro ($800 million) program too late, but he rejected calls for his resignation.
An unmanned jet built for U.S. Navy high-altitude maritime surveillance missions has made its first flight. Northrop Grumman Corp. says the MQ-4C Triton took off from Palmdale, Calif., Wednesday and completed a 90-minute flight. The aircraft is designed to fly missions lasting up to 24 hours at altitudes greater than 10 miles, allowing coverage out 2,000 nautical miles.
A Wayne State University researcher understands that the three most important things about real estate also apply to small ground robotic vehicles: location, location, location. A recently published paper describes the development of a technique called LOBOT that provides accurate, real-time, 3D positions in both indoor and outdoor environments.
The Navy will make its first attempt to launch an unmanned aircraft the size of a fighter jet from an aircraft carrier on Tuesday, marking a significant step toward the possibility of expanded drone use in future conflicts. The X-47B can reach an altitude of more than 40,000 feet, has a range of more than 2,100 nautical miles and can reach high subsonic speeds.
When Michael Gore stands, it's a triumph of science and engineering. Eleven years ago, Michael Gore was paralyzed from the waist down in a workplace accident, yet he rises from his wheelchair to his full 6-foot-2-inches and walks across the room with help from a lightweight wearable robot. Still at least a year away from the market, the 27-pound Indego is the lightest of the powered exoskeletons that are now appearing in greater numbers.

You get into your car and ask it to get you home in time for the start of the big game, stopping off at your favorite Chinese restaurant on the way for takeout. But the car informs you that the road past the Chinese restaurant is closed for repairs, and you will have to choose a different place. You select a nearby Korean restaurant from the options the car suggests. Autonomous devices could soon collaborate with humans in this way.
The Navy on Thursday inaugurated its first squadron with both manned and unmanned aircraft. Military officials launched the effort by reactivating the Helicopter Maritime Strike Squadron 35, known as the "Magicians" or HSL-35, which served for 19 years before being deactivated in 1992.
Whether reaching for a book out of a cluttered cabinet or pruning a bush in the backyard, a person’s arm frequently makes contact with objects during everyday tasks. Animals do it too, when foraging for food, for example. Much in the same way, robots are now able to intelligently maneuver within clutter, gently making contact with objects while accomplishing a task. This new control method has wide applications.
A consortium of Washington-based organizations will soon submit the final section of a proposal to site an unmanned aircraft system research and testing facility in central Washington. If successful, the proposal to the Federal Aviation Administration (FAA) will result in the FAA naming the Pacific Northwest Unmanned Aerial Systems Flight Center as one of six U.S. testing facilities later this year.
As long as buildings have windows, engineers will fret about how best to keep them clean. Rice University engineering students are no exception and are working on better ways to keep skyscrapers shiny. The WashBOT team of seniors based at Rice’s Oshman Engineering Design Kitchen is part of a multiyear robotics project to automate the process of cleaning recessed windows in buildings.
Israel's air force is on track to developing drones that within four to five decades would carry out nearly every battlefield operation executed today by piloted aircraft, a high-ranking Israeli officer told The Associated Press Sunday. The officer, who works in the field of unmanned aerial vehicle intelligence, said Israel is speeding up research and development of such unmanned technologies for air, ground, and naval forces.
The biggest thing in operating rooms these days is a million-dollar, multi-armed robot named da Vinci, used in nearly 400,000 surgeries in America last year. But now the high-tech helper is under scrutiny over reports of problems, including several deaths that may be linked with it, and the high cost of using the robotic system. Is it time to curb the robot enthusiasm?
The biggest thing in operating rooms these days is a million-dollar, multi-armed robot named da Vinci, used in nearly 400,000 surgeries in America last year—triple the number just four years earlier. But now the high-tech helper is under scrutiny over reports of problems, including several deaths that may be linked with it, and the high cost of using the robotic system.
Although bladder cancer is the sixth most common form of cancer in the U.S. and the most expensive to treat, the basic method that doctors use to treat it hasn’t changed much in more than 70 years. A research team may soon be changing that dramatically after having developed a prototype telerobotic platform designed to be inserted through natural orifices—in this case the urethra—that can provide surgeons with a much better view, making it easier to remove tumors.
Virginia Tech College of Engineering researchers have unveiled a life-like, autonomous robotic jellyfish the size and weight of a grown man, 5 foot 7 inches in length and weighing 170 pounds. The prototype robot, nicknamed Cyro, is a larger model of a robotic jellyfish the same team unveiled in 2012. The earlier robot, dubbed RoboJelly, is roughly the size of a man's hand, and typical of jellyfish found along beaches.
It's a good bet that in the not-so-distant future aerial drones will be part of Americans' everyday lives, performing countless useful functions. A far cry from the killing machines whose missiles incinerate terrorists, these generally small, unmanned aircraft will help farmers more precisely apply water and pesticides to crops, saving money and reducing environmental impacts. They'll help police departments find missing people, reconstruct traffic accidents and act as lookouts for SWAT teams.
Robot butlers that tidy your house or cook you a meal have long been the dream of science-fiction writers and artificial intelligence researchers alike. But if robots are ever going to move effectively around our constantly changing homes or workspaces performing such complex tasks, they will need to be more aware of their own limitations, according to researchers at Massachusetts Institute of Technology.
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.
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.
Software engineers at five European universities have developed a cloud-computing platform for robots. The platform allows robots connected to the Internet to directly access the powerful computational, storage, and communications infrastructure of modern data centers—the giant server farms behind the likes of Google, Facebook, and Amazon—for robotics tasks and robot learning.
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.
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.
The strong, flapping flight of bats offers great possibilities for the design of small aircraft, among other applications. By building a robotic bat wing, Brown University researchers have uncovered flight secrets of real bats: the function of ligaments, the elasticity of skin, the structural support of musculature, skeletal flexibility, upstroke, downstroke.
Engineers at Harvard University have already shown that their unusual “soft” robots can already stand, walk, wriggle under obstacles, and change colors. Now, using small explosions produced by a mix of methane and oxygen, these researchers have designed a soft robot that can leap as much as a foot in the air.
