Real-Time Excavation Trajectory Modulation for Slip and Rollover Prevention

RA-L 2025

We propose a novel real-time excavation trajectory modulation framework on a slope for an autonomous excavator with a low-level digital kinematic control as common for hydraulic industrial excavators. Excavation on a slope is challenging because of a higher risk of slips and rollovers. To deal with

Online 3D Edge Reconstruction of Wiry Structures From Monocular Image Sequences

RA-L 2023

Three-dimensional (3D) reconstruction of wiry structures from vision suffers from thin geometry, lack of texture, and severe self-occlusions. We propose an online 3D edge reconstruction framework that uses monocular image sequences to reconstruct the wiry structures whose skeletons are mainly straig

Precision Motion Control of Robotized Industrial Hydraulic Excavators via Data-Driven Model Inversion

RA-L 2022

This work proposes a novel precision motion control framework of robotized industrial hydraulic excavators via data-driven model inversion. Rather than employing a single neural network to approximate the whole excavator dynamics, including input delays and dead-zones, we construct a physics-inspire
