US Army picks winners to build light and medium robotic combat vehicles

By: Jen Judson

WASHINGTON — The U.S. Army has picked winners to build base platforms for its light- and medium-class robotic combat vehicles, according to a service statement released Jan. 9.

The Army's Combat Capabilities Development Command and the service's Next Generation Combat Vehicle Cross-Functional Team “intends” — pending successful negotiations — to award a contract to QinetiQ North America to build four RCV-light prototypes and another contract to Textron to build four RCV-medium prototypes, the release stated.

Through a rapid contracting mechanism, the National Advanced Mobility Consortium is coordinating the Army's awards to industry, and the service expects to be officially under contract with both companies by mid-February, according to the statement.

While it was anticipated the Army would award up to two contracts per category at the end of the second quarter this fiscal year, it appears the awards have come earlier and are both limited to one company.

The prototypes, according to the statement, will be used to “determine the feasibility of integrating unmanned vehicles into ground combat operations. The Light and Medium RCVs will be used to conduct a company-level experiment at the end of 2021."

Results from that effort, as well as a platoon-level experiment in March 2020 and several virtual experiments, will help the Army decide in 2023 how it wants to proceed with robots on the battlefield.

“Robots have the potential to revolutionize the way we conduct ground combat operations,” Brig. Gen. Ross Coffman, director of the NGCV CFT, said in the statement. “Whether that's giving increased fire power to a dismounted patrol, breaching an enemy fighting position, or providing [chemical, biological, radiological, nuclear and explosive] reconnaissance, we envision these vehicles providing commanders more time and space for decisions and reducing risk to soldiers.”

Out of a large pool of whitepaper submissions, a Textron and Howe & Howe team, a team of QinetiQ North America and Pratt & Miller, HDT Global, and Oshkosh were each issued a request for prototype proposals in the RCV-light competition in October 2019.

Three teams were picked to move on in the RCV-medium competition in November 2019: General Dynamics Land Systems, QinetiQ North America, and the Textron and Howe & Howe team.

It is noteworthy that the companies selected to build prototypes in each category are the only two companies to have offerings in both the light and medium competitions, demonstrating potentially that they are the only companies with the flexibility to build in both categories.

At the Association of the U.S. Army's annual conference in October, Textron and Howe & Howe dramatically unveiled their RCV Ripsaw M5, which is based on the latter's deep history of building unmanned ground vehicles, but adds technology like scalable armor and suspension as well as mobility options to cope with the challenges expected in the future fight. FLIR Systems is also part of the team, contributing its advanced sensors.

“Bringing together Howe & Howe, Textron Systems and FLIR Systems really represents a dream team,” Textron CEO Lisa Atherton said in a statement released at the show. “We formed this team based on our shared focus to serve this customer with disruptive ideas and proven experience, and we are dedicated to meeting and exceeding their requirements through the RCV program.”

The team told Defense News before the AUSA conference that it planned to submit a version of Ripsaw both for the light and medium variant of the Army's robotic combat vehicle.

The Qinetiq and Pratt & Miller team submitted a variant of the Expeditionary Modular Autonomous Vehicle tailored toward the Army's RCV-light requirements. The offering combines Qinetiq's modular open-architecture control systems with Pratt & Miller's advanced mobility platform.

The Army is also examining the utility of an RCV-heavy variant but is using robotic M113 armored personnel carriers as surrogate platforms for evaluations. That effort will focus on manned-unmanned teaming in a robotic wingman formation, with a manned Bradley Infantry Fighting Vehicle serving as the platform for the robot's operators.

Rolls-Royce développe un démarreur électrique pour le futur chasseur de la Royal Air Force
Depuis 2014, Rolls-Royce développe un démarreur électrique qui devrait être intégré au moteur du Tempest, le futur avion de combat de la Royal Air Force britannique. Le tout devrait prendre moins de place et générer de l'énergie de manière plus intelligente, ce qui permettra à l'appareil d'optimiser ses consommations, tout en étant moins gros que l'actuel Eurofighter Typhoon. Le Tempest, futur avion de combat de la Royal Air Force britannique devrait comporter nettement plus d'éléments électriques que son prédécesseur, l'Eurofighter Typhoon. Dans cette optique, Rolls-Royce a confirmé être en train de développer, pour l'appareil, un nouveau système de démarrage des turboréacteurs, électrique et intégré. Le constructeur planche sur le projet depuis plus de cinq ans. Dès 2014, il met au point un générateur de démarrage électrique, entièrement intégré au cœur d'un moteur à turbine à gaz. Le programme du démonstrateur est baptisé "Embedded Electrical Starter Generator", ou E2SG. Moins de place pour un appareil moins gros "Le générateur électrique embarqué permettra de gagner de la place et fournira une importante quantité d'énergie aux futurs chasseurs", explique dans un communiqué Conrad Banks, ingénieur en chef du programme chez Rolls-Royce. Les générateurs actuels génèrent de l'énergique à l'aide d'une boîte de vitesses située sous le moteur. Un élément qui requiert un certain espace. N'en ayant plus besoin, le Tempest pourra être plus petit et donc plus furtif. En 2017, le projet est entré dans sa deuxième phase. Un second générateur électrique a été intégré à l'autre partie du turboréacteur. Le réseau électrique de l'appareil est désormais capable de stocker de l'énergie et une fonction intelligente gère l'alimentation de tous les systèmes. Baptisé Power Manager, il "utilise des algorithmes et prend des décisions intelligentes en temps réel pour répondre à la demande électrique de l'avion, tout en optimisant d'autres facteurs, comme la consommation de carburant ou la température du moteur, pour prolonger la durée de vie des composants", détaille le communiqué. Une troisième phase devrait bientôt voir le jour, avec l'intégration d'un nouveau système de gestion thermique et l'électrification d'autres composants. Rolls-Royce prévoit également la présentation prochaine d'un démonstrateur taille réelle qui comprendra toutes les innovations susmentionnées. https://www.usinenouvelle.com/article/rolls-royce-developpe-un-demarreur-electrique-pour-le-futur-chasseur-de-la-royal-air-force.N919119

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/
