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

BAE awarded $111M contract for Navy's Archerfish mine neutralizers
Ed Adamczyk Sept. 21 (UPI) -- BAE Systems announced a contract Monday worth up to $111 million to supply the U.S. Navy with Archerfish mine neutralizers. Archerfish is used by the US Navy's MH-60S Helicopter squadrons as part of their Airborne Mine Neutralization System capability, and reduces the need to put diving personnel in the water for clearance missions, according to the company. The system is a remote-controlled, torpedo-like device that can be launched and operated from a surface ship, helicopter or an unmanned underwater vehicle. Using fiber optic data link relays, Archerfish can provide real-time sonar pictures of potential targets through on-board sensors, a BAE statement on Monday said. "Archerfish not only keeps sailors safer, it also reduces the number and cost of mine clearance missions," said Brooke Hoskins, director of products and training for BAE's maritime services business. Each AMNS device consists of a Launch and Handling System for all data processing during a mission, and up to four elements called destructors, which handle target acquisition and demolition. The Navy established a requirement for rapid neutralization of bottom and moored sea mines to support operations in littoral zones, confined straits, choke points and the amphibious objective area. This is the fourth Navy contract awarded to BAE since 2003 to build AMNS devices, which will be manufactured at the company's facilities in Britain. The number of devices ordered by the Navy was not reported. https://www.upi.com/Defense-News/2020/09/21/BAE-awarded-111M-contract-for-Navys-Archerfish-mine-neutralizers/3721600703371/

International militaries reveal interest in US Army’s Future Vertical Lift program
By: Valerie Insinna WASHINGTON — The U.S. Army's Future Vertical Lift program is getting “significant” levels of attention from militaries around the globe, eight of which have already sent letters of interest to the service, the head of the FVL program said Sept. 10. “We're working with multiple international partners on bilateral agreements ... and we're pursuing those letters of interest,” Brig. Gen. Wally Rugen, director of the Army's Future Vertical Lift Cross-Functional Team, said during a panel at the Defense News Conference. Rugen declined to comment on what nations have expressed interest in the program but said that the Army has remained engaged with those countries during the COVID-19 pandemic. “We've done a number of virtual meetings with our partners to keep the momentum up during COVID, and we have very good planning on our 2021 engagements going forward,” he said. “The exportability, interoperability and the cooperation is being studied deeply. [We're] talking about [liaison officers] coming into the FVL office.” The Army intends to develop and field two rotorcraft in the early 2030s as part of the FVL program: future attack reconnaissance aircraft, which will take over the reconnaissance mission currently performed by a mix of the AH-64 Apache helicopter and RQ-7 Shadow drone; and the future long-range attack aircraft, which will replace the UH-60 Black Hawk helicopter. Both are on budget and on schedule, Rugen said. The service recently awarded 10 contracts worth a total of $29.75 million to companies that will develop a series of “air-launched effects” for its future vertical lift aircraft, which could include sensors, mesh networking technologies and other payloads. Future contracts for air-launched effects could present sales opportunities for foreign defense contractors, Rugen said during the panel. “There's a lot of opportunity for our international partners in this space. I think it's very wide open. And the reason it's so wide open is” is that such technologies are “affordable and effective,” he said. In addition to the effort focused on air-launched effects, the Army is in the middle of multiple future tactical UAV demonstrations, which will ultimately pave the way for a replacement of the Shadow drone. Soldiers are assessing the four candidate systems through a series of field tests and exercises: the V-Bat system offered by Martin UAV and Northrop Grumman; Textron's Aerosonde HQ; the Arcturus UAV JUMP 20; and L3Harris' FVR-90. “The soldiers are extremely excited but giving us good feedback,” Rugen said. “They're not being easy on us [on] what to fix, what to do different. And that's the kind of data and information that's going to give us just a rock-solid requirement that we can move out on and get this into units where it's militarized, ruggedized and ready to go.” https://www.defensenews.com/smr/defense-news-conference/2020/09/10/international-militaries-are-keeping-an-eye-on-the-us-armys-future-vertical-lift-program/
