Learning Forward Dynamics Model and Informed Trajectory Sampler for Safe Quadruped Navigation

1 code implementation19 Apr 2022 Yunho Kim, Chanyoung Kim, Jemin Hwangbo

For autonomous quadruped robot navigation in various complex environments, a typical SOTA system is composed of four main modules -- mapper, global planner, local planner, and command-tracking controller -- in a hierarchical manner.

Concurrent Training of a Control Policy and a State Estimator for Dynamic and Robust Legged Locomotion

1 code implementation11 Feb 2022 Gwanghyeon Ji, Juhyeok Mun, Hyeongjun Kim, Jemin Hwangbo

In this paper, we propose a locomotion training framework where a control policy and a state estimator are trained concurrently.

D-Grasp: Physically Plausible Dynamic Grasp Synthesis for Hand-Object Interactions

1 code implementation CVPR 2022 Sammy Christen, Muhammed Kocabas, Emre Aksan, Jemin Hwangbo, Jie Song, Otmar Hilliges

We introduce the dynamic grasp synthesis task: given an object with a known 6D pose and a grasp reference, our goal is to generate motions that move the object to a target 6D pose.

Learning agile and dynamic motor skills for legged robots

2 code implementations24 Jan 2019 Jemin Hwangbo, Joonho Lee, Alexey Dosovitskiy, Dario Bellicoso, Vassilios Tsounis, Vladlen Koltun, Marco Hutter

In the present work, we introduce a method for training a neural network policy in simulation and transferring it to a state-of-the-art legged system, thereby leveraging fast, automated, and cost-effective data generation schemes.
