Size Doesn't Matter: Material-State Reinforcement Learning for Excavator Transferable Soil Manipulation
Lennart Werner, Pol Eyschen, Sean Costello +3
Earthmoving tasks such as excavation, backfilling, or embankment construction require deliberate repositioning of deformable soil. For these tasks, human operators use all shovel f…
High Precision Hydraulic Excavator Control for Heavy-Duty Grading
Lennart Werner, Pol Eyschen, Sean Costello +2
High-precision heavy-duty grading is a common step in earthworks, traditionally carried out manually by skilled operators. Removing a significant amount of material while achieving…
Calibrated Dynamic Modeling for Force and Payload Estimation in Hydraulic Machinery
Lennart Werner, Pol Eyschen, Sean Costello +2
Accurate real-time estimation of end effector interaction forces in hydraulic excavators is a key enabler for advanced automation in heavy machinery. Accurate knowledge of these fo…
Direction Finding for Software Defined Radios with Switched Uniform Circular Arrays
Lennart Werner, Markus Gardill, Marco Hutter
Accurate Direction of Arrival (DoA) estimation is critical for applications in robotics and communication, but high costs and complexity of coherent multi-channel receivers hinder…
