An Error-State Model Predictive Control on Connected Matrix Lie Groups for Legged Robot Control

IROS 2022poster

This paper reports on a new error-state Model Predictive Control (MPC) approach to connected matrix Lie groups for robot control. The linearized tracking error dynamics and the linearized equations of motion are derived in the Lie algebra. Moreover, given an initial condition, the linearized trackin…

A New Framework for Registration of Semantic Point Clouds from Stereo and RGB-D Cameras

ICRA 2021poster

This paper reports on a novel nonparametric rigid point cloud registration framework, Semantic Continuous Visual Odometry (CVO), that jointly integrates geometric and semantic measurements such as color or semantic labels into the alignment process and does not require explicit data association. The…

Continuous Direct Sparse Visual Odometry from RGB-D Images

RSS 2019poster

This paper reports on a novel formulation and evaluation of visual odometry from RGB-D images. Assuming a static scene, the developed theoretical framework generalizes the widely used direct energy formulation (photometric error minimization) technique for obtaining a rigid body transformation that…
