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…
MPC-Based Hierarchical Task Space Control of Underactuated and Constrained Robots for Execution of Multiple Tasks
Jaemin Lee, Seung Hyeon Bang, Efstathios Bakolas +1
This paper proposes an MPC-based controller to efficiently execute multiple hierarchical tasks for underactuated and constrained robotic systems. Existing task-space controllers or…
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…
