A set of papers was accepted at the IEEE Aerospace Conference 2019, namely:
The work of Autonomous Robots Lab was presented at NASA JPL and potential for collaboration was investigated.
Together with our CMU partners we presented our status for our "NRI:Collaborative Research: Multi-Modal Characterization of DOE-EM Facilities" at the NRI PI Meeting 2018.
In this work we present a multi--sensor fusion algorithm for reliable odometry estimation in GPS--denied and degraded visual environments. The proposed method utilizes information from both the visible and thermal spectra for landmark selection and prioritizes feature extraction from informative image regions based on a metric over spatial entropy. Furthermore, inertial sensing cues are integrated to improve the robustness of the odometry estimation process.
The University of Nevada, Reno, leading a team of international partners that includes ETH Zurich, University of California, Berkeley, Sierra Nevada Corporation and Flyability, has been awarded the prestigious DARPA Subterranean Challenge grant for the proposal “CERBERUS: CollaborativE walking & flying RoBots for autonomous ExploRation in Underground Settings.”
Project CERBERUS will bring groundbreaking robotic solutions into the field of subterranean deployments. CERBERUS envisions a system of walking and flying robots equipped with multi-modal perception systems, navigation and mapping autonomy, and self-organized networked communications that enable robust and reliable navigation, exploration, mapping, and object search in complex, sensing-degraded, stringent, dynamic, and rough underground settings. The robotic embodiment of these capabilities will enable unprecedented levels of operational awareness in such environments, and will thus become a game changer for a large variety of subterranean operations in both civilian and military domains.
Team CERBERUS is based on the collaboration between a team of experts that for the last years have been at the forefront of walking and flying robots research. This includes: Professor Kostas Alexis, director of the Autonomous Robots Lab at the University of Nevada, Reno; Professor Marco Hutter of the Robotic Systems Lab at ETH Zurich; Professor Roland Siegwart of the Autonomous Systems Lab at ETH Zurich; Professor Mark Mueller of the HiPeR Lab at U.C. Berkeley; Sierra Nevada Corporation based in Sparks, Nevada and Flyability based in Switzerland. The cumulative expertise of the team enables the successful development and reliable operation of the CERBERUS system in the SubT Challenge.
In alignment with the goals and details of the DARPA SubT challenge, CERBERUS aims to achieve exciting and superior performance results in a sequence of competition events that in their combination demand to facilitate resilient subterranean autonomy.
Those events will include the autonomous exploration and search inside a man-made tunnel network (“Tunnel Circuit”), a multi-level urban underground structure (“Urban Circuit”) and a natural cave environment (“Cave Circuit”), as well as a comprehensive test environment involving all challenges of the previously mentioned types (“Final Event”). The first circuit is scheduled for August 2019.
Our team looks forward to the novel research investigations and to breaking new ground towards resilient robotic autonomy in subterranean operations. The CERBERUS technological solution aims to be a stepping stone for complex applications in domains such as search and rescue, reconnaissance, inspection, as well as security and military tasks.
Project CERBERUS started on Sept. 18, and is based on funding of up to $4.275 million for the three phases of the project and the opportunity to win an additional $2 million reward at the Final Event.
