Whole-Body Human Kinematics Estimation using Dynamical Inverse Kinematics and Contact-Aided Lie Group Kalman Filter
Prashanth Ramadoss, Lorenzo Rapetti, Yeshasvi Tirupachuri +6
Full-body motion estimation of a human through wearable sensing technologies is challenging in the absence of position sensors. This paper contributes to the development of a model…
An Experimental Comparison of Floating Base Estimators for Humanoid Robots with Flat Feet
Prashanth Ramadoss, Stefano Dafarra, Silvio Traversaro +1
Extended Kalman filtering is a common approach to achieve floating base estimation of a humanoid robot. These filters rely on measurements from an Inertial Measurement Unit (IMU) a…
Online Non-linear Centroidal MPC for Humanoid Robot Locomotion with Step Adjustment
Giulio Romualdi, Stefano Dafarra, Giuseppe L'Erario +3
This paper presents a Non-Linear Model Predictive Controller for humanoid robot locomotion with online step adjustment capabilities. The proposed controller considers the Centroida…
DILIGENT-KIO: A Proprioceptive Base Estimator for Humanoid Robots using Extended Kalman Filtering on Matrix Lie Groups
Prashanth Ramadoss, Giulio Romualdi, Stefano Dafarra +3
This paper presents a contact-aided inertial-kinematic floating base estimation for humanoid robots considering an evolution of the state and observations over matrix Lie groups. T…
Modeling of Visco-Elastic Environments for Humanoid Robot Motion Control
Giulio Romualdi, Stefano Dafarra, Daniele Pucci
This manuscript presents a model of compliant contacts for time-critical humanoid robot motion control. The proposed model considers the environment as a continuum of spring-damper…
Non-Linear Trajectory Optimization for Large Step-Ups: Application to the Humanoid Robot Atlas
Stefano Dafarra, Sylvain Bertrand, Robert J. Griffin +3
Performing large step-ups is a challenging task for a humanoid robot. It requires the robot to perform motions at the limit of its reachable workspace while straining to move its b…
