Torque Controlled Locomotion of a Biped Robot with Link Flexibility
Nahuel A Villa, Pierre Fernbach, Maximilien Naveau +4
When a big and heavy robot moves, it exerts large forces on the environment and on its own structure, its angular momentum can varysubstantially, and even the robot's structure can…
Learning How to Walk: Warm-starting Optimal Control Solver with Memory of Motion
Teguh Santoso Lembono, Carlos Mastalli, Pierre Fernbach +2
In this paper, we propose a framework to build a memory of motion for warm-starting an optimal control solver for the locomotion task of a humanoid robot. We use HPP Loco3D, a vers…
SL1M: Sparse L1-norm Minimization for contact planning on uneven terrain
Steve Tonneau, Daeun Song, Pierre Fernbach +3
One of the main challenges of planning legged locomotion in complex environments is the combinatorial contact selection problem. Recent contributions propose to use integer variabl…
Contact Planning for the ANYmal Quadruped Robot using an Acyclic Reachability-Based Planner
Mathieu Geisert, Thomas Yates, Asil Orgen +2
Despite the great progress in quadrupedal robotics during the last decade, selecting good contacts (footholds) in highly uneven and cluttered environments still remains an open cha…
