Robots slightly shorter than the average human may be able to connect portions of the offline world to the online world digitally. Knightscope Incorporated will soon be testing the K5 and K10 robots, which can autonomously prowl through large areas and small spaces, collecting significant amounts of data from their immediate surroundings. Applications include perimeter surveillance of military bases and inspection of power plants.

In previous rodeos, teams competed in simulations that included a tornado-damaged nuclear reactor scenario. Operators were tasked with quickly locating and moving simulated fuel rods, stopping the flow of radioactive water from running into a storm drain system and minimizing radioactive contamination on the robot.

Civilian and military bomb squad teams from across the country are participating in the 7th Annual Western National Robot Rodeo and Capability Exercise this week. Hosted by Sandia National Laboratories, the event pits these experts against each other to determine who can most effectively defuse dangerous situations with the help of robots.

Researchers at Brown University, Providence, Rhode Island, have developed a robotic batwing that could one day lead to more dynamic, dexterous and sophisticated wings for aircraft. The National Science Foundation, which supports the research, announced the breakthrough in its online publication Science Nation, along with a video. Unlike the wings of birds or insects, batwings are more like the human hand with many joints and skin, allowing bats to change the shape of their wings in-flight, researchers say.

Researchers at the U.S. Army Research Laboratory and Johns Hopkins University have discovered methods to control folding pathways and enable sequential folding on a millimeter scale using a low-intensity laser beam. Lasers at a low intensity worked as a trigger for tagging applications. Developers are fabricating sheets of millimeter-size structures that serve as battery-free wireless actuators that fold when exposed to a laser operating at eye-safe infrared wavelengths. The metallic structures may respond even to high-powered LED lighting.

Scientists at Argonne National Laboratory have developed a method to control microrobots by placing them in liquid and using magnetic forces. The researchers confined the robots-which are only half a millimeter wide-between two liquids. The application of alternating magnetic fields caused them to assemble into spiky shapes dubbed asters. By applying a second small magnetic field parallel to the surface, the scientists can make the robots pick up, transport and put down nonmagnetic particles. Already, four asters positioned together collected free-floating particles, and another one picked up a glass bead that weighed four times as much as itself.

Three U.S. Army units-two active duty and one National Guard-are preparing to go to war with robots armed, for now, with nonlethal weapons. Additionally, the Army expects later this year to finish the requirements document for the Multi-Mission Unmanned Ground System, which will include an armed version capable of deploying with small tactical units, possibly as early as 2013.

While more than 2,000 unmanned ground systems have already proved critical to the fight against improvised explosive devices, armed systems will tackle a wider array of missions, including force protection and tactical deployments.

The mid-1970s TV series "The Six Million Dollar Man" is no longer a mere futuristic dream. While today's injured warfighters aren't able to run 60 miles an hour or possess superhuman strength like fictional character Steve Austin, they are still achieving amazing results through robotics and prosthetics. And now, many are returning to service in fully functional mode. Technology Editor George I. Seffers looks at U.S. Army efforts to make soldiers physically whole again in his article, "Robotics Research Gives Life to Artificial Limbs," in this issue of SIGNAL Magazine.

It's nice when Fido obeys commands, but isn't it even better when he instinctively anticipates those directives? Apply this concept to unmanned systems-robotics to be exact-and the warfighter has a more foolproof companion by his side on the battlefield. That's the idea driving the U.S. Army Research Laboratory's Robotics Collaborative Technology Alliance (CTA) to advance the state of the art in unmanned technologies and move them more quickly into theater. Robots will eschew remote-control guidance, relying on programming that gives them autonomy via artificial intelligence.
