Proposes the importance of position and force control and information in low-cost single-arm and dual-arm robot manipulation for research in daily tasks. Demonstrates the effectiveness of bilateral control-based imitation learning Bi-ACT. Examples include egg transportation and bottle cap opening.
DABI: Evaluation of Data Augmentation Methods Using Downsampling in Bilateral Control-Based Imitation Learning with Images
Evaluation of data augmentation methods using downsampling in bilateral control-based imitation learning with images. Addresses different sensor frequencies.
Bi-ACT: Bilateral Control-Based Imitation Learning via Action Chunking with Transformer
Proposes Bi-ACT, which fuses the well-known Action Chunking with Transformers (ACT) from ALOHA/ACT with bilateral control-based imitation learning using position and force control. The importance of force control for generalization to unseen objects became clear.
LfDT: Learning Dual-Arm Manipulation from Demonstration Translated from a Human and Robotic Arm
Proposes LfDT, a framework for dual-arm coordination tasks that performs domain translation from human-robot demonstration data pairs to robot-robot demonstration data, enabling imitation learning. Cross-domain correspondence in a CycleGAN-like manner.
MRReP: Mixed Reality-based Hand-drawn Reference Path Editing Interface for Mobile Robot Navigation
A mixed-reality interface for mobile robots in which users draw a hand-drawn reference path (HRP) on the floor; a custom planner integrates it into the ROS 2 navigation stack for autonomous driving. In a within-subject study against a conventional 2D map interface, MRReP improved path-specification accuracy, usability, and perceived workload, and enabled more stable route specification in the physical environment.
Mixed Reality-Based Robot Navigation Interface Using Spatial Pointing and Speech with Large Language Model
Mixed Reality (MR)-based robot navigation interface that replaces complex hand gestures with a natural, multimodal interface combining spatial pointing and LLM-based speech interaction. Significantly reduces task completion time and workload compared to conventional gesture-based MR systems.
MR-UBi: Mixed Reality-Based Underwater Robot Arm Teleoperation System with Reaction Torque Indicator via Bilateral Control
Mixed Reality (MR)-based underwater robot arm teleoperation system with reaction torque indicator for underwater environments. Achieves intuitive operation via bilateral control.
EmoLo: Emotion-Inspired Expressive Locomotion via Single-Policy Reinforcement Learning on Low-Cost Bipedal Robots
Style-conditioned reinforcement learning for emotion-inspired expressive locomotion on the low-cost bipedal robot Open Duck Mini V2. Three discrete styles—Happy, Neutral, and Sad—are served by a single shared policy, with sim-to-real transfer via ONNX inference on hardware.
