Geometry-Aided Vision-Based Localization of Future Mars Helicopters in Challenging Illumination Conditions

ICRA 2026poster

Planetary exploration using aerial assets has the potential for unprecedented scientific discoveries on Mars. While NASA's Mars helicopter Ingenuity proved flight in Martian atmosphere is possible, future Mars rotorcraft will require advanced navigation capabilities for long-range flights. One such …

Inter-Robot Range Measurements in Pose Graph Optimization

IROS 2020poster

For multiple robots performing exploration in a previously unmapped environment, such as planetary exploration, maintaining accurate localization and building a consistent map are vital. If the robots do not have a map to localize against and do not explore the same area, they may not be able to fin…

Thermal-Inertial Odometry for Autonomous Flight Throughout the Night

IROS 2019poster

Thermal cameras can enable autonomous flight at night without GPS. However, image-based navigation in the thermal infrared spectrum has been researched significantly less than in the visible spectrum. In this paper, we demonstrate closed-loop controlled outdoor flights at night on a quadrotor. Our s…
