The DARPA Subterranean (SubT) Challenge aims to develop innovative technologies that would augment operations underground. The SubT Challenge will explore new approaches to rapidly map, navigate, search, and exploit complex underground environments, including human-made tunnel systems, urban underground, and natural cave networks.
Tunnels can extend many kilometers in length and include highly constrained passages, multiple levels, and vertical shafts. Urban underground environments are often more structured and constructed out of human-made materials, but can have complex layouts that cover multiple stories and/or span multiple city blocks. Natural cave networks often have irregular geological structures, with both constrained passages and large caverns, and unpredictable topologies often stretching large distances in extent and depth.
These environments present significant challenges for situational awareness. In time-sensitive scenarios, such as active combat operations or disaster response settings, warfighters and first responders face increased technical challenges including difficult terrain, unstable structures, degraded environmental conditions, severe communication constraints, and expansive areas of operation. For these reasons, natural cave networks, human-made tunnels, and urban underground environments have consistently played a central role in historical warfare and military operations. The SubT Challenge will ensure that our warfighters and first responders are equipped with the technologies and capabilities they need to effectively execute their future missions.
Given the complexity of these environments, the SubT Challenge seeks to inspire technological breakthroughs to offer key insights into:
The SubT Challenge is organized into two competitions (Systems and Virtual),
each with two tracks (DARPA-funded and self-funded). Teams in the Systems
tracks will develop and demonstrate physical systems to compete in live
competitions on physical, representative subterranean courses, and focus on
advancing and evaluating novel physical solutions in realistic field
environments. Teams in the Virtual tracks will develop software and algorithms
using virtual models of systems, environments, and terrain to compete in
simulation-based events, and explore larger-scale runs in simulated
environments that explore significantly expanded scenario sizes and durations.
Teams will compete in three preliminary Circuit events and a Final event
pursuing high-risk and high-reward approaches. The Final event, planned for
2021, will put teams to the test with courses that incorporate diverse
challenges from all three environments. Teams in the Systems track will
compete for up to $2 million in the Systems Final event, with up to $200,000
in additional prizes available for self-funded teams in each of the Systems
Circuit events. Teams in the Virtual track will compete for up to $1.5 million
in the Virtual Final event, with additional prizes of up to $500,000 for
self-funded teams in each of the Virtual Circuit events.
