Wild Visual Navigation: Fast Traversability Learning via Pre-Trained Models and Online Self-Supervision

no code implementations10 Apr 2024 Matías Mattamala, Jonas Frey, Piotr Libera, Nived Chebrolu, Georg Martius, Cesar Cadena, Marco Hutter, Maurice Fallon

Natural environments such as forests and grasslands are challenging for robotic navigation because of the false perception of rigid obstacles from high grass, twigs, or bushes.

SiLVR: Scalable Lidar-Visual Reconstruction with Neural Radiance Fields for Robotic Inspection

no code implementations11 Mar 2024 Yifu Tao, Yash Bhalgat, Lanke Frank Tarimo Fu, Matias Mattamala, Nived Chebrolu, Maurice Fallon

We present a neural-field-based large-scale reconstruction system that fuses lidar and vision data to generate high-quality reconstructions that are geometrically accurate and capture photo-realistic textures.

Fast Traversability Estimation for Wild Visual Navigation

no code implementations15 May 2023 Jonas Frey, Matias Mattamala, Nived Chebrolu, Cesar Cadena, Maurice Fallon, Marco Hutter

We demonstrate the advantages of our approach with experiments and ablation studies in challenging environments in forests, parks, and grasslands.

Predicting Dense and Context-aware Cost Maps for Semantic Robot Navigation

no code implementations17 Oct 2022 Yash Goel, Narunas Vaskevicius, Luigi Palmieri, Nived Chebrolu, Cyrill Stachniss

The preliminary experiments suggest that the cost maps generated by our network are suitable for the MPC and can guide the agent to the semantic goal more efficiently than a baseline approach.
