DARPA wants commanding robots to work like a video game

By: Kelsey D. Atherton

In a fake city in Mississippi, DARPA is training robots for war. In December 2019, at a camp southeast of Hattiesburg, hundreds of robots gathered to scout an urban environment, and then convert that scouting data into useful information for humans.

Conducted at Camp Shelby Joint Forces Training Center, the exercise was the third test of DARPA's OFFensive Swarm-Enable Tactics (OFFSET) program. OFFSET is explicitly about robots assisting humans in fighting in urban areas, with many robots working together at the behents of a small group of infantry to provide greater situational awareness than a human team could achieve on its own.

The real-time nature of the information is vital to the vision of OFFSET. It is one thing to operate from existing maps, and another entirely to operate from recently mapped space, with continuing situational awareness of possible threats and other movement through the space.

Dating back to at least 2017, OFFSET is in part an iterative process, with contractors competing for and receiving awards for various ‘sprints,' or narrower short-turnaround developments in coding capabilities. Many of these capabilities involve translating innovations from real-time strategy video games into real life, like dragging-and-dropping groups units to give them commands.

For the exercise at Camp Shelby, the swarms involved both ground and flying robots. These machines were tasked with finding specific items of interest located in buildings at Camp Shelby's Combined Arms Collective training Facility. To assist the robots in the field experiment, organized seeded the environment with AprilTags. These tags, which are similar to QR codes but trade complexity of data stored for simplicity and robustness in being read at difference, were used to mark the sites of interest, as well as hazards to avoid.

In practical use, hazards seldom if ever arrive with barcodes explicitly labeling themselves as hazards, but for training the AprilTags provide a useful scaffolding while the robots coordinate in other ways.

“As the swarm relayed information acquired from the tags,” wrote DAPRA, “human swarm tacticians adaptively employed various swarm tactics their teams had developed to isolate and secure the building(s) containing the identified items.”

That information is relayed in various ways, from updated live maps on computer screens to floating maps displayed in real time in augmented reality headsets.

As foreshadowed by countless works of cyberpunk fiction, these “human swarm tacticians” interfaced with both the real world and a virtual representation of that world at once. Commanding robots to move in real space by manipulating objects in a virtual environment, itself generated by robots exploring and scouting the real space, blurs the distinction between artificial and real environments. That these moves were guided by gesture and haptic feedback only further underscores how deeply linked commanding robots can be to augmented reality.

The gesture and haptic feedback command systems were built through sprinter contracts by Charles River Analytics, Inc., Case Western University, and Northwestern University, with an emphasis on novel interaction for human-swarm teaming.

Another development, which would be as at home in the real-time strategy game series Starcraft as it is in a DARPA OFFSET exercise, is the operational management of swarm tactics from Carnegie Mellon University and Soar Technology. Their developments allowed the swarm to search and map a building on its own, and to automate resource allocation in the process of accomplishing tasks.

For now, the heart of the swarm is as a scouting organism built to provide information to human operators.

    MDA to deliver mission-critical SAR information for maritime surveillance

    ichmond, BC - MDA, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.), (NYSE: MAXR) (TSX: MAXR), today announced that it has signed a multi-million dollar contract with the South African National Space Agency (SANSA) for a one-year maritime surveillance program that includes the delivery of synthetic aperture radar (SAR) data products from the RADARSAT-2 satellite, using MDA's global network of ground receiving stations. The contract includes two additional option years. As part of the Presidential program Operation Phakisa, SANSA has been tasked to acquire SAR imagery with the aim of enhancing the monitoring and protection of South Africa's coastal regions and oceans. Initiatives under this program are considered crucial in accelerating the delivery of South Africa's development priorities. Operations Phakisa estimates that the approximate total contribution of coastal resources (marine fishing, port and harbour development, attractive lifestyles, recreation and tourism) is 35% of South Africa's GDP. The information provided by the SAR data contributes to ensuring improved governance and enables the securing of South African resources, such as the National Ocean and Coastal Information System. The South African Exclusive Economic Zone (EEZ) is roughly 1.5 million square km and forms part of the economic resources and trade routes of South Africa. The Council for Scientific and Industrial Research (CSIR), South Africa's central and premier scientific research and development organization will create the ship and oil detection products for SANSA to share with various government agencies. “RADARSAT-2 provides a unique method of cost-effectively and accurately monitoring very large areas and providing information in near real-time, demonstrating immediate value to users,” said Mike Greenley, group president of MDA. “MDA has decades of remote sensing expertise to help our customers anticipate and address their most complex mission-critical challenges with confidence.” Under this contract, using RADARSAT-2 information, MDA will provide systematic weekly broad-area surveillance over South Africa's EEZ and on-demand high-resolution image acquisitions. RADARSAT-2 Ocean Surveillance Mode is well suited for broad area maritime surveillance, and is unique as a single scene covers over 250,000 ㎢ and allows for the detection of ships and oil within the coastal and offshore regions regardless of light or weather condition. https://mdacorporation.com/news/pr/pr2018091001.html

    Lockheed Signals Change Is Coming With New CEO

    Michael Bruno Lockheed Martin Chairman, CEO and President Marillyn Hewson became the prime example of how to stumble into the corner office of the Pentagon's top contractor and still provide laudable business results. Now, as she hands off the reins to an enigmatic successor, Lockheed stakeholders hope the uncertainty ahead will be just as lucrative. On March 16, the Bethesda, Maryland-based prime—the largest contractor to the U.S. Defense Department by annual sales—surprised many followers with the news that current Lockheed board member James “Jim” Taiclet, Jr. will become CEO and president on June 15, while Hewson becomes executive chairman. Lockheed also promoted Frank St. John, current executive vice president of the company's Rotary and Mission Systems (RMS) division, to become chief operating officer (COO)—a role that Hewson technically held last, and briefly, before her January 2013 appointment as chief executive. Before that, the COO role was mostly held by Chris Kubasik prior to his downfall at Lockheed. Stephanie Hill, now senior vice president for enterprise business transformation, was appointed to succeed St. John as executive vice president for RMS. These appointments also are effective June 15. Hewson is 66 years old and Taiclet is 59. The company, which does not have a retirement rule, had not announced a formal transition plan or successor process. Nevertheless, industry insiders were watching movements—such as St. John's rise and recent board appointments—and analysts said they assume the transition was planned before the ongoing COVID-19 crisis erupted. While the announcement was a surprise, the timing was not—due to Hewson's age and the fact that Lockheed ended 2019 with a record $144 billion backlog of work and a stock price that has more than tripled under Hewson, including the recent COVID-19-related pullback. Still, many observers are intrigued by the selection. “While Marillyn's retirement has been in the cards for a while, we were not expecting Lockheed to go outside the company for its new CEO,” say analysts at Vertical Research Partners. “Taiclet has an impressive pedigree based on his resume, but from an A&D perspective, he is an unknown quantity. . . . But with Marillyn sticking around as chairman, and a very experienced cohort of senior Lockheed managers, we are not expecting there to be any revolutionary change as a result of this appointment.” Cowen analysts also noted that St. John's appointment as COO further bookends Taiclet with experienced Lockheed managers. St. John, 53, joined Lockheed more than 30 years ago and as COO is naturally positioned as a potential future CEO, analysts say. Taiclet is currently chairman, president and CEO of American Tower, a real estate investment holding company and owner/operator of wireless and broadband communications networks, where he has held the executive reins since 2003. He joined that company in 2001 and, according to Lockheed, is credited with guiding American Tower's transformation from a U.S.-centric focus to a multinational business outlook. Analysts said he also was central in leading mergers and acquisitions as part of the company's expansion. American Tower announced an immediate replacement for Taiclet but said he will remain chairman and an advisor through June 14. Taiclet previously served as president of Honeywell Aerospace Services and before that was vice president for engine services at the Pratt & Whitney division of United Technologies (UTC). He also worked as a consultant at McKinsey & Co., specializing in telecommunications and aerospace strategy and operations. He is a retired U.S. Air Force pilot and Persian Gulf War veteran. Loren Thompson, a Lexington Institute consultant to Lockheed, says Hewson's selection of Taiclet seems calculated to continue her emphasis on tight financial management and good customer relations while positioning the leading prime for a changing demand environment. “That environment will be characterized by two shifts from previous years,” Thompson writes. “First, the defense budget will enter a flat to declining period very different from the spending increases of the early Trump [administration] years. Second, the preference of military customers for nontraditional suppliers who think like entrepreneurial enterprises rather than government contractors will continue to grow.” Hewson's selection of Taiclet also is telling because she has won the respect of many industry insiders, analysts and advisers. While unplanned, Hewson's tenure as CEO was deemed successful by most. “Hewson's tenure is known for operational execution with such programs as the F-35, while having a successful oversight in maintaining key businesses—such as in the evolving area of space with wins such as Next-Gen OPIR and GPS IIIF,” say Jefferies analysts. Company sales grew at a 5% compound annual growth rate from $45.4 billion in 2013 to an expected $63.3 billion this year. Taiclet's takeover sounds to many like more of the same—but different. “This is the first time Lockheed Martin has promoted someone who did not rise through the corporation to be president and CEO,” writes Capital Alpha Partners analyst Byron Callan. “We find it intriguing that he has a commercial background and wonder if that's not a different direction the company starts to explore in 2020-25.” https://aviationweek.com/defense-space/supply-chain/lockheed-signals-change-coming-new-ceo
