CERBERUS stands for “CollaborativE walking & flying RoBots for autonomous ExploRation in Underground Settings” and throughout the three years of the project developed a team of legged and aerial robots capable of autonomously exploring diverse subterranean environments such as underground mines and tunnels, metropolitan sub-surface infrastructure, and natural cave networks. After successfully going through the Tunnel Circuit and the Urban Circuit of the DARPA Subterranean Challenge, Team CERBERUS qualified for the Final Event (the “Cave Circuit” planned for early 2020 was canceled due to the Covid-19 pandemic).
In the Final Event, DARPA designed an environment involving branches representing all three challenges of the “Tunnel Circuit”, the “Urban Circuit” and the “Cave Circuit”. Robots had to explore, search for objects (“artifacts”) of interest, and report their accurate location within underground tunnels, infrastructure similar to a subway, and natural caves and paths with extremely confined geometries, tough terrain, and severe visual degradation (including dense smoke).
Team CERBERUS deployed a diverse set of robots with the prime systems being four ANYmal C legged systems. In the Prize Round of the Final Event, the team won the competition and scored 23 points by correctly detecting and localizing 23 of 40 of the artifacts DARPA had placed inside the environment. The second team, “CSIRO Data61” also scored 23 points but reported the last artifact with a slight further delay to DARPA thus the tiebraker was in favor of Team CERBERUS. The third team, “MARBLE” scored 18 points.
The DARPA Subterranean Challenge was one of the rare types of global robotic competition events pushing the frontiers for resilient autonomy and calling teams to develop novel and innovative solutions with the capacity to help critical sectors such as search and rescue personnel and the industry in domains such as mining and beyond. The level of achievement of Team CERBERUS is best understood by looking at all the competitors in the “Systems Competition” of the Final Event.
