SoftBiT: Soft Bimanual Teleoperation with Proprioceptive Visual Augmentation

Tai Inui, Uksang Yoo, Jeffrey Ichnowski, Jean Oh

HRI2025, VAM-HRI Workshop

We proposed SoftBit, a teleoperation interface that enhances user awareness through real-time soft robot finger shape visualization in extended reality (XR). The system combines proprioceptive sensing with an XR headset (Meta Quest2) to provide users with intuitive visual feedback about finger deformations during manipulation tasks. SoftBiT’s key innovation is a real-time sim-to-real pipeline that estimates and visualizes soft finger shapes, helping users better understand robot-object interactions even when direct visual feedback is limited.

TriForce Band: Leveraging Triaxial Tactile Sensing for Wrist Force-Myography Gesture Recognition

Tai Inui, Tamon Miyake, Yushi Wang, Shigeki Sugano

UIST2025 Poster

We introduced TriForce Band, a compact gesture input wristband built from a single triaxial magnetic tactile sensor module. A five-participant, ten-gesture experiment resulted with a classification accuracy of 93.0%.

Geodiffussr: Generative Terrain Texturing with Elevation Fidelity

Tai Inui, Alex Matsumura, Edgar Simo-Serra

Preprint

We introduced Geodiffussr, a flow matching-based pipeline that generates realistic, text prompt-guided texture map while strictly respecting an input Digital Elevation Map (DEM). We fuse geometry into the UNet at coarse-to-fine resolutions with Multi-scale Content Aggregation (MCA), allowing the model to respect global landforms and local ridgelines alike.

Events

Introduction to AI: Computer Vision, Robotics, and 3D Reconstruction

Kuma Lab x Google Developer Group on Campus (GDGoC)

Kuma Lab and Google Developer Group on Campus collaborated to host a hands-on workshop on AI. We introduced the basic concepts of AI, through its applications in 3 fields: Computer Vision, Robot Learning, and 3D Reconstruction.

Introduction to Unity

Google Developer Group on Campus (GDGoC)

Under Google Developer Group on Campus, we hosted a hands-on workshop on game development with Unity. After introducing the basic concepts of Unity, we recreated Flappy Bird with the audience.

Robot and Art

Kuma Lab

The core members of Kuma Lab hosted a workshop on "Robotic Art", where we explored how the two fields that seem to be far apart: Robotics and Art, can go together to form an interesting topic of research.

Introduction to Reinforcement Learning

Kuma Lab

Under Kuma Lab, I hosted a virtual session on introductory reinforcement learning. This covered basic concepts like Q-learning, Policy Gradient, and Actor-Critic.

Projects

Language Conditioned Autonomous Pick and Place via VLA Models

Tokyo Robotics

During my internship at Tokyo Robotics, I collaborated with a friend to deploy a VLA model onto a humanoid robot. It can now perform pick and place tasks from language instructions.

TableTopTwin: A Table-top Size Telepresence Robot

GEEK Camp Hackathon

Made a tabletop size telepresence robot that mimics your movements via a webcam. Won the top award at the GEEK Camp Hackathon.
