OTRetarget: Joint Robot and Object Motion Retargeting via Optimal Transport
Guillaume Besset, Erwann Carn, Timothée Carecchio +5
Transferring human motion to humanoid robots requires adapting the demonstrated motion to the robot morphology while preserving interactions with the environment. This is particula…
Infeasible optimization problems and the hierarchical augmented Lagrangian method in imitation learning
Roland Andrews, Justin Carpentier, Ajay Sathya
Imitation learning (IL) is an effective approach to train complex robotics policies. Recent works have introduced hard constraints into imitation-learning optimization problems to…
Constrained Dynamics Simulation: More With Less
Ajay Suresha Sathya
Efficient robot dynamics simulation is a fundamental problem key for robot control, identification, design and analysis. This research statement explores my current progress in thi…
PV-OSIMr: A Lowest Order Complexity Algorithm for Computing the Delassus Matrix
Ajay Suresha Sathya, Wilm Decre, Jan Swevers
We present PV-OSIMr, an efficient algorithm for computing the Delassus matrix (also known as the inverse operational space inertia matrix) for a kinematic tree, with the lowest ord…
Efficient Constrained Dynamics Algorithms based on an Equivalent LQR Formulation using Gauss' Principle of Least Constraint
Ajay Suresha Sathya, Herman Bruyninckx, Wilm Decre +1
We derive a family of efficient constrained dynamics algorithms by formulating an equivalent linear quadratic regulator (LQR) problem using Gauss principle of least constraint and…
