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.

Cyber innovation at the forefront of UK’s approach to modern warfare
Defence Secretary Penny Mordaunt has announced £22 million in funding for Army cyber operations centres Speaking this evening at the NATO Cyber Defence Pledge Conference in London, Defence Secretary Penny Mordaunt will address the need for the UK and NATO members to recognise offensive cyber as central to modern warfare. As the UK has already demonstrated against Daesh in the Middle East, it can be a vital tool to keep people in the UK and overseas safe from virtual and physical threats. The military continues to develop its cyber capabilities as part of the £1.9 billion investment into the National Cyber Security Strategy, focused on boosting the UK's cyber security. Recent UK innovations have included the creation of the National Cyber Security Centre which brings together government, intelligence agencies and the private sector into one organisation. The state-of-the-art Defence Cyber School, which marked its first anniversary in March this year, is also training the next generation of cyber experts. The Defence Secretary will today expand that commitment, announcing £22 million in funding to stand up new Army cyber operations centres across the UK. Defence Secretary Penny Mordaunt will say: We know all about the dangers. Whether the attacks come from Russia, China or North Korea. Whether they come from hacktivists, criminals or extremists. Whether its malware or fake news. Cyber can bring down our national infrastructure and undermine our democracy. It's time to pay more than lip service to cyber. We must convince our adversaries their advances simply aren't worth the cost. Cyber enemies think they can act with impunity. We must show them they can't. That we are ready to respond at a time and place of our choosing in any domain, not just the virtual world. We need coherent cyber offense as well as defence. So today I can announce we will be investing £22m to create new cyber operations centres. Putting the Army at the forefront of information warfare, the centres will draw together cyber capability from a range of sources – including both national intelligence and open source data – to give the Army the competitive edge across all environments. The cyber centres will provide the Army with 24/7 information and analysis, dispel misinformation and give the UK Armed Forces and our allies the upper hand on emerging digital threats. The centres are likely to be used to support overseas operations, humanitarian missions, and efforts to protect UK digital communications on home soil. The centres will work with existing Army capabilities, such as 77 Brigade – a modern and information-focused British Army unit – but will also have regular contact with joint and other national security organisations. Major General Tom Copinger-Symes, General Officer Commanding Force Troops Command: These new cyber centres will allow the Army and Defence to transform the way we use data, at speed, so that we can compete with our adversaries in a way fit for the 21st Century. Combining artificial intelligence with our military analysts will help us better understand threats and exploit opportunities, in turn enabling us to get the truth out much more rapidly, quashing the noise of disinformation from our enemies. While details on locations are yet to be confirmed, building in support of the centres is due to begin next year, with operations expected to commence in the early 2020s. The MOD is embracing transformation at an ever-faster rate and investments in truly high-tech innovation, such as in the provision of cutting-edge cyber centres, that will develop the Armed Forces of the future. https://www.gov.uk/government/news/cyber-innovation-at-the-forefront-of-uks-approach-to-modern-warfare
