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…
Obstacle-Avoidant Leader Following with a Quadruped Robot
Carmen Scheidemann, Lennart Werner, Victor Reijgwart +5
Personal mobile robotic assistants are expected to find wide applications in industry and healthcare. For example, people with limited mobility can benefit from robots helping with…
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…
Dynamic Throwing with Robotic Material Handling Machines
Lennart Werner, Fang Nan, Pol Eyschen +3
Automation of hydraulic material handling machinery is currently limited to semi-static pick-and-place cycles. Dynamic throwing motions which utilize the passive joints, can greatl…
