  US Army chief: How COVID-19 will impact modernization is a wait-and-see situation

  By: Jen Judson WASHINGTON — It's realistic for the U.S. Army to wait and see how the new coronavirus might affect its ambitious plans to modernize the force, Army Chief of Staff Gen. James McConville told Defense News in a March 18 interview. With major economic centers on both U.S. coasts restricting public gatherings, and with most of the country attempting social distancing to avoid the spread of the virus, industry as of this week appeared to still be sorting out how it would handle its own workforce and keep employees safe from infection. Much of what the Army is doing to address its top modernization priorities depends on industry collaboration and efforts. “We're watching what is happening,” McConville said. “We do have some high-priority tests that we think are continuing to go, and industry is doing the same thing that we're doing — they're putting measures in place with their people. They're weighing risks to the force and, really, risk to their missions as they do that.” Some high-priority tests will continue, he said, while “other ones will slow down.” While he did not list all high-priority tests that would likely go on, McConville noted that the Army is still moving forward with contract awards and making progress where it can. He pointed to the service's recent contract awards to Bell and Sikorsky to continue to develop and test aircraft for the Army's Future Long Range Assault Aircraft program. That contract was awarded on the expected timeline. The Army also tested its Extended Long-Range Cannon Artillery system at Yuma Proving Ground, Arizona, on March 6, but that was only as uncertainty was just beginning to build in the U.S. regarding the spread of COVID-19. The service has an abundance of important milestones planned across its modernization priorities this year, to include a robust flight test program for the Precision Strike Missile at White Sands Missile Range in New Mexico, and a likely imminent flight test of a jointly developed hypersonic glide body. The Army also plans to award contracts to build Future Attack Reconnaissance Aircraft prototypes this month. But it's unclear how other programs will move forward. The previously troubled Integrated Battle Command System for air and missile defense is finally slated to go into a limited-user test in May this year, which is critical to the program's success. The Army planned to conduct a series of industry days to restart its effort to competitively procure a Bradley Infantry Fighting Vehicle replacement, but according to sources, a virtual industry day to kick things off has been postponed and the Army plans to post informational slides to industry on Beta.Sam.Gov in the near term instead. “The acquisition cycle continues to move on,” McConville said, “and we'll have a better idea over the next 30 to 60 days, as more measures are implemented in certain states, what and how that really plays out.” https://www.defensenews.com/smr/army-modernization/2020/03/19/army-chief-how-covid-19-will-affect-army-modernization-is-a-wait-and-see-situation/

  Robots Autonomously Navigate Underground in DARPA Challenge

  Whether robots are exploring caves on other planets or disaster areas here on Earth, autonomy enables them to navigate extreme environments without human guidance or access to GPS. The Subterranean Challenge, or SubT, is testing this kind of cutting-edge technology. Sponsored by the Defense Advanced Research Projects Agency (DARPA), the contest concluded its second circuit on Wednesday, Feb. 27. Taking first in the competition was CoSTAR, a 12-robot, 60-person team led by NASA's Jet Propulsion Laboratory (there were also winners declared for a separate, virtual competition). SubT is divided into four circuits spread over three years. With each, teams program their robots to navigate a complex underground course. The first contest, held last August, took place in a mine. For the most recent, called the Urban Circuit, teams raced against one another in an unfinished power plant in Elma, Washington. Each team's robots searched for a set of 20 predetermined objects, earning a point for each find. For the Urban Circuit, CoSTAR earned 16 points; the No. 2 team, with 11 points, was Explorer, led by Carnegie Mellon University. "The goal is to develop software for our robots that lets them decide how to proceed as they face new surprises," said CoSTAR's team lead Ali Agha of JPL. "These robots are highly autonomous and for the most part make decisions without human intervention." CoSTAR, which stands for Collaborative SubTerranean Autonomous Robots, brought machines that can roll, walk or fly, depending on what they encounter. Along the way, the bots have to map the environment and find objects like a warm mannequin that simulates a disaster survivor or a lost cellphone with a Wi-Fi signal. This particular course, which aims to simulate an urban environment, also included a carbon dioxide leak and a warm air vent. Joining the team for the Urban Circuit was a four-legged robot called Spot, which was provided by Boston Dynamics. "One of the two courses we had to run had multiple levels, so it was great that the Boston Dynamics robots were fantastic on stairs," says Joel Burdick, a Caltech professor and JPL research scientist. He is the leader of the Caltech campus section of the CoSTAR team. As the bots explore, they send back video and digital maps to a single human supervisor, who they remained in radio contact with for the first 100 feet (30 meters) or so of the course. They can extend that range by dropping communications nodes, a kind of wireless repeater. Once out of contact, it's up to each robot to decide whether to proceed or backtrack in order to update the team. Each must also rely on fellow robots to access different levels of the course. For example, a wheeled robot might request a quadrupedal one to climb or descend a flight of stairs. "These courses are very, very challenging, and most of the difficulty lies in communicating with the robots after they've gone out of range," Agha said. "That's critical for NASA: We want to send robots into caves on the Moon or Mars, where they have to explore on their own." Mapping caves on the Moon or Mars could identify good shelters for future astronauts. Moreover, if it exists at all, microbial life has a better chance of survival under the surface of Mars or within the icy seas of planetary moons, like Europa, Enceladus and Titan. NASA wants to search for life in these regions, where robots would be frequently out of contact. The next circuit in the Subterranean Challenge will be set in an undisclosed natural cave network this August. A final circuit that blends tunnels, urban environments and natural caves will take place in August of 2021. Teams competing in that final event have the opportunity to win up to $2 million in funding from DARPA. CoSTAR, includes JPL; Caltech, which manages JPL for NASA; MIT; KAIST (Korea Advanced Institute of Science and Technology); Sweden's Lulea University of Technology; and industry partners.
