Real-to-Sim: Predicting Residual Errors of Robotic Systems with Sparse Data using a Learning-based Unscented Kalman Filter

no code implementations7 Sep 2022 Alexander Schperberg, Yusuke Tanaka, Feng Xu, Marcel Menner, Dennis Hong

Achieving highly accurate dynamic or simulator models that are close to the real robot can facilitate model-based controls (e. g., model predictive control or linear-quadradic regulators), model-based trajectory planning (e. g., trajectory optimization), and decrease the amount of learning time necessary for reinforcement learning methods.

Simultaneous Contact-Rich Grasping and Locomotion via Distributed Optimization Enabling Free-Climbing for Multi-Limbed Robots

no code implementations4 Jul 2022 Yuki Shirai, Xuan Lin, Alexander Schperberg, Yusuke Tanaka, Hayato Kato, Varit Vichathorn, Dennis Hong

While motion planning of locomotion for legged robots has shown great success, motion planning for legged robots with dexterous multi-finger grasping is not mature yet.

SABER: Data-Driven Motion Planner for Autonomously Navigating Heterogeneous Robots

1 code implementation3 Aug 2021 Alexander Schperberg, Stephanie Tsuei, Stefano Soatto, Dennis Hong

We present an end-to-end online motion planning framework that uses a data-driven approach to navigate a heterogeneous robot team towards a global goal while avoiding obstacles in uncertain environments.

Risk-Averse MPC via Visual-Inertial Input and Recurrent Networks for Online Collision Avoidance

no code implementations28 Jul 2020 Alexander Schperberg, Kenny Chen, Stephanie Tsuei, Michael Jewett, Joshua Hooks, Stefano Soatto, Ankur Mehta, Dennis Hong

In this paper, we propose an online path planning architecture that extends the model predictive control (MPC) formulation to consider future location uncertainties for safer navigation through cluttered environments.
