Hierarchical Action Chunking Transformer: Learning Temporal Multimodality from Demonstrations with Fast Imitation Behavior

IROS 2024poster

Behavioral cloning from human demonstrations has succeeded in programming a robot to generate fine-grained motion, but it is still challenging to learn multimodal trajectories such as with various speeds. This restricts the use of a robot dataset collected by multiusers because the different profici…

RGBD Fusion Grasp Network with Large-Scale Tableware Grasp Dataset

IROS 2023poster

This paper proposes a novel approach to address the technical challenges of stable object grasping, particularly in the context of handling tableware in a home environment. Handling tableware is particularly important, yet challenging, due to the flat nature of most tableware objects and the need to…

Model-Free Optimal Estimation and Sensor Placement Framework for Elastic Kinematic Chain

ICRA 2019poster

We propose a novel model-free optimal estimation and sensor placement framework for a high-DOF (degree-of-freedom) EKC (elastic kinematic chain) with only a limited number of IMU (inertial measurement unit) sensors based on POD (proper orthogonal decomposition) and MAP (maximum a posteriori) estimat…

LASDRA: Large-Size Aerial Skeleton System with Distributed Rotor Actuation

ICRA 2018poster

Electrical motor and hydraulic actuation widely-used in robotics are “internal actuation” with their actuators sitting at the joint between two links. This internal actuation is fundamentally limiting to construct a large-size dexterously-articulated robot, since any external force (and its own link…
