In this work, a computational resources-aware parameter adaptation method for visual-inertial navigation systems is proposed with the goal of enabling the improved deployment of such algorithms on computationally constrained systems. Such a capacity can prove critical when employed on ultra-lightweight systems or alongside mission critical computationally expensive processes. To achieve this objective, the algorithm proposes selected changes in the vision front-end and optimization back-end of visual-inertial odometry algorithms, both prior to execution and in real time based on an online profiling of available resources. The method also utilizes information from the motion dynamics experienced by the system to manipulate parameters online. The general policy is demonstrated on three established algorithms, namely S-MSCKF, VINS-Mono and OKVIS and has been verified experimentally on the EuRoC dataset. The proposed approach achieved comparable performance at a fraction of the original computational cost.

![DARPA SubT Urban Circuit: Autonomous Exploration in the Satsop Abandoned Power Plant
In this video, a mission of the Alpha Aerial Scout of Team CERBERUS during the DARPA Subterranean Challenge Urban Circuit event is presented. The Alpha Robot operates inside the Satsop Abandoned Power Plant and performs autonomous exploration. The robot autonomy relies on a resilient multi-modal localization and mapping solution fusing LiDAR, vision and inertial sensing, combined with a graph-based exploration path planner responsible to identify optimized viewpoints to explore the unknown setting in a collision-free manner. The same planner is futher responsible for the automated return-to-home behavior of the robot.
This deployment took place during the 3rd field trial of team CERBERUS during the Urban Circuit event of the DARPA Subterranean Challenge. The Urban Circuit contained the Alpha and Beta courses (name not to be confused with that of the robot which is also called Alpha). This test is in the Alpha course. Team CERBERUS deploys a combination of legged, flying and roving robotic systems.
