TreeLoc: 6-DoF LiDAR Global Localization in Forests via Inter-Tree Geometric Matching
Minwoo Jung, Nived Chebrolu, Lucas Carvalho de Lima +3
Reliable localization is crucial for navigation in forests, where GPS is often degraded and LiDAR measurements are repetitive, occluded, and structurally complex. These conditions…
An Efficient Locally Reactive Controller for Safe Navigation in Visual Teach and Repeat Missions
MatÃas Mattamala, Nived Chebrolu, Maurice Fallon
To achieve successful field autonomy, mobile robots need to freely adapt to changes in their environment. Visual navigation systems such as Visual Teach and Repeat (VT&R) often ass…
Visual Servoing-based Navigation for Monitoring Row-Crop Fields
Alireza Ahmadi, Lorenzo Nardi, Nived Chebrolu +1
Autonomous navigation is a pre-requisite for field robots to carry out precision agriculture tasks. Typically, a robot has to navigate through a whole crop field several times duri…
Building Forest Inventories with Autonomous Legged Robots -- System, Lessons, and Challenges Ahead
MatÃas Mattamala, Nived Chebrolu, Jonas Frey +5
Legged robots are increasingly being adopted in industries such as oil, gas, mining, nuclear, and agriculture. However, new challenges exist when moving into natural, less-structur…
Online Tree Reconstruction and Forest Inventory on a Mobile Robotic System
Leonard FreiÃmuth, Matias Mattamala, Nived Chebrolu +3
Terrestrial laser scanning (TLS) is the standard technique used to create accurate point clouds for digital forest inventories. However, the measurement process is demanding, requi…
Sapling-NeRF: Geo-Localised Sapling Reconstruction in Forests for Ecological Monitoring
Miguel Ãngel Muñoz-Bañón, Nived Chebrolu, Sruthi M. Krishna Moorthy +4
Saplings are key indicators of forest regeneration and overall forest health. However, their fine-scale architectural traits are difficult to capture with existing 3D sensing metho…
