Control and Evaluation of a Humanoid Robot with Rolling Contact Knees
Seung Hyeon Bang, Carlos Gonzalez, Junhyeok Ahn +2
In this paper, we introduce the humanoid robot DRACO 3 by providing a high-level description of its design and control. This robot features proximal actuation and mechanical artifa…
Data-Driven Safety Verification for Legged Robots
Junhyeok Ahn, Seung Hyeon Bang, Carlos Gonzalez +2
Planning safe motions for legged robots requires sophisticated safety verification tools. However, designing such tools for such complex systems is challenging due to the nonlinear…
Data-Efficient and Safe Learning for Humanoid Locomotion Aided by a Dynamic Balancing Model
Junhyeok Ahn, Jaemin Lee, Luis Sentis
In this letter, we formulate a novel Markov Decision Process (MDP) for safe and data-efficient learning for humanoid locomotion aided by a dynamic balancing model. In our previous…
Control of A High Performance Bipedal Robot using Viscoelastic Liquid Cooled Actuators
Junhyeok Ahn, Donghyun Kim, SeungHyeon Bang +2
This paper describes the control, and evaluation of a new human-scaled biped robot with liquid cooled viscoelastic actuators (VLCA). Based on the lessons learned from previous work…
Fast Kinodynamic Bipedal Locomotion Planning with Moving Obstacles
Junhyeok Ahn, Orion Campbell, Donghyun Kim +1
We present a sampling-based kinodynamic planning framework for a bipedal robot in complex environments. Unlike other footstep planner which typically plan footstep locations and th…
