On the Conic Complementarity of Planar Contacts
Yann de Mont-Marin, Louis Montaut, Jean Ponce +2
We present a unifying theoretical result that connects two foundational principles in robotics: the Signorini law for point contacts, which underpins many simulation methods for pr…
End-to-End and Highly-Efficient Differentiable Simulation for Robotics
Quentin Le Lidec, Louis Montaut, Yann de Mont-Marin +2
Over the past few years, robotics simulators have largely improved in efficiency and scalability, enabling them to generate years of simulated data in a few hours. Yet, efficiently…
PhysPose: Refining 6D Object Poses with Physical Constraints
Martin Malenický, Martin CÃfka, Médéric Fourmy +4
Accurate 6D object pose estimation from images is a key problem in object-centric scene understanding, enabling applications in robotics, augmented reality, and scene reconstructio…
Differentiable Simulation of Soft Robots with Frictional Contacts
Etienne Ménager, Louis Montaut, Quentin Le Lidec +1
In recent years, soft robotics simulators have evolved to offer various functionalities, including the simulation of different material types (e.g., elastic, hyper-elastic) and act…
Contact Models in Robotics: a Comparative Analysis
Quentin Le Lidec, Wilson Jallet, Louis Montaut +3
Physics simulation is ubiquitous in robotics. Whether in model-based approaches (e.g., trajectory optimization), or model-free algorithms (e.g., reinforcement learning), physics si…
From Compliant to Rigid Contact Simulation: a Unified and Efficient Approach
Justin Carpentier, Louis Montaut, Quentin Le Lidec
Whether rigid or compliant, contact interactions are inherent to robot motions, enabling them to move or manipulate things. Contact interactions result from complex physical phenom…
