  What’s so sweet about sugar cube-sized robots?

  By: Kelsey D. Atherton If there is anything the future is lacking, it's robots the size of Chiclets. Draper, working under a grant from the Defense Advanced Research Projects Agency, is creating centimeter-sized robots, for future use in rescue work. The project is named “SHort-Range Independent Microrobotic Platforms,” or “SHRIMP” for short. And short is the nature of the game. SHRIMP is based on the 4 cm long, 1.5 g Harvard Ambulatory MicroRobot (HAMR), and wants to shrink it down to a single cubic centimeter. That will require microelectromechanical systems, 3D printing, piezoelectric actuators and, this is crucial, low-power sensors. Once all of that is in place, Draper claims the microbot will be able to jump, sense, navigate and control itself. The design will rely on feet inspired by living creatures to give it extra friction on rough and vertical terrain, and inertial measurement to detect where it is on the ground. “The microrobotic platform capabilities enabled by SHRIMP will provide the DoD with significantly more access and capability to operate in small spaces that are practically inaccessible to today's state-of-the-art robotic platforms,” declared DARPA in the proposer's day note. “Such capability will have impact in search and rescue, disaster relief, infrastructure inspection, and equipment maintenance, among other operations.” The exact “how” of what these robots will do in disaster relief, inspection, maintenance or other operations is yet to be determined, and will largely hinge on the sensors that can be fit to the platform. The most useful thing a small robot can do is get into a space and send information back to humans about that space, but that's hardly the only metric to evaluate the platform. As part of the SHRIMP program, DARPA will have the robot designs compete through a series of events modeled after the Olympics. These include high jump, long jump, weightlifting, shot put, tug of war, rock piling, steeplechase, biathlon, vertical ascent — all ways to find out what useful tasks tiny robots can do. There's a world of speculation between a dime-sized robot that can pile rocks and a useful military tool, but the fact that DARPA is invested in the technology as a platform suggests that, should the technology get there, the design will have some unexpected utility. In the meantime, DARPA's interest suggests there's good odds on a future market for sensors designed for dice-sized robots. https://www.c4isrnet.com/unmanned/robotics/2019/06/12/what-does-darpa-want-with-sugarcube-sized-robots/

  A-10 Enhanced Wing Assembly Replacement Program Comes To An End

  A-10s Get New Wings Workers at the Ogden Air Logistics Complex at Hill Air Force Base have installed the last of 173 new wings on A-10 Thunderbolt II aircraft, finalizing a project that started in 2011 with aircraft 80-0173. The ALC's 571st Aircraft Maintenance Squadron swapped wings on 162 A-10s as part of the A-10 Enhanced Wing Assembly replacement program. The remaining 11 were installed at Osan Air Base in the Republic of Korea. The new wings are expected to last for up to 10,000 equivalent flight hours without a depot inspection. In addition, a better wire harness design was created for easier wing removal and to lessen the chance of damaging the wing during the process. “From a warfighter point of view, bringing this program to a successful conclusion was a significant accomplishment for the entire enterprise team,” said Stephen Zaiser, 571st AXMS director. Working on an aircraft that has been flying for nearly 40 years wasn't without challenges. The modifications included having to make new parts for the fuselage and having to bring other A-10 parts up from the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan Air Force Base, Arizona. “At the end of the program, making sure we had all the pieces and parts that we needed to make that happen required a really significant team effort,” Zaiser said. “I think the fact that we produced the aircraft so successfully is a testament to the whole team, the special program office, Boeing and others that were a part of making it all work.” Lt. Col. Ryan Richardson, 514th Flight Test Squadron commander and A-10 test pilot, flew the functional check flight on the last A-10 to receive the new wings to deem the aircraft airworthy. “It flew great and passed all the FCF checks,” Richardson said. “It's unusual to have an airplane in production for as long as this one was and have it come out and fly as well as this one did.” Introduced into the U.S. Air Force aircraft inventory in 1976, the venerable A-10 is the only production-built aircraft for close air support. The aircraft was made to fly close to the ground in support of friendly ground troops, drop heavy loads of weapons, attacks armored vehicles and tanks, and can be called in to attack enemy ground forces. With heavy stresses put on the wings over the weapon system's lifetime and with its full-service life still unknown, the Air Force decided to replace some of the fleet's wings in order for the weapon system to remain airworthy. In 2007, Boeing was awarded a $1.1 billion contract to build replacement wings at its Macon, Georgia, plant that will allow the aircraft to continue flying into the late 2030s. “The A-10 Special Program Office, in partnership with the Ogden ALC, is poised to keep the aircraft flying for the foreseeable future,” said Michael Hackett, A-10 SPO chief engineer. http://www.aero-news.net/index.cfm?do=main.textpost&id=e3fe8bb4-6d74-4d69-845e-d6e204fcfbe7
