Shadow Hand Teleop System

MVIG-RHOS, SJTU

About

  Recently, with the emergence of GPT, robot planning and reasoning systems based on basic large language models have been rapidly developed, but the current SOTA system (Robot Transformer-2, RoboAgent) already suffers from a number of shortcomings:
  (a) Insufficient robustness to external disturbances: current mainstream models perform poorly in the face of external disturbances, are difficult to replan strategies in real time in dynamic environments, and often require manual intervention or are unable to automatically adapt to new situations, and thus are inefficient in the face of external changes.
  (b) Data Efficiency Problem: Many SOTA systems require a large amount of data during training, which can lead to data inefficiency. Improving these systems to increase data efficiency is an important challenge.
  (c) Insufficient scalability and migratability: current SOTA systems are usually only able to perform well in specific tasks or domains, and struggle to handle a wider range of tasks. Even for very similar environments, it is difficult to do policy migration.
  Specifically, on dexterous hand reasoning and planning: current mainstream models perform well in executing strategies in static environments, but still lack robust and effective Re-Planning capabilities in the face of external disturbances. Our research goal is to address this problem by proposing a new planning approach with a dual-layer planner with replaceable strategies and goals at both coarse and fine grains to cope with changing environments; at the same time, we will introduce a planner and an executor capable of generating or replacing new strategies when planning errors are detected at both the vision and executor side to ensure that the target task is accomplished.

EgoPCA: A New Framework for Egocentric Hand-Object Interaction Understanding

MVIG-RHOS, SJTU

demo
With the surge in attention to Egocentric Hand-Object Interaction (Ego-HOI), large-scale datasets such as Ego4D and EPIC-KITCHENS have been proposed. However, most current research is built on resources derived from third-person video action recognition. This inherent domain gap between first- and third-person action videos, which have not been adequately addressed before, makes current Ego-HOI suboptimal. This paper rethinks and proposes a new framework as an infrastructure to advance Ego-HOI recognition, contributing a new baseline, comprehensive pretrain sets, and balanced test sets, which are complete with a training-finetuning strategy. With our new framework, we not only achieve state-of-the-art performance on Ego-HOI benchmarks but also build several new and effective mechanisms and settings to advance further research. We believe our data and the findings will pave a new way for Ego-HOI understanding.

RHOS

About

Hi, this is the website of RHOS team at MVIG. We study Human Activity Understanding, Visual Reasoning, and Embodied AI. We are building a knowledge-driven system that enables intelligent agents to perceive human activities, reason human behavior logics, learn skills from human activities, and interact with environment.

Research Interests:

(S) Embodied AI: how to make agents learn skills from humans and interact with human & scene & object.
(S-1) Human Activity Understanding: how to learn and ground complex/ambiguous human activity concepts (body motion, human-object/human/scene interaction) and object concepts from multi-modal information (2D-3D-4D).
(S-2) Visual Reasoning: how to mine, capture, and embed the logics and causal relations from human activities.
(S-3) General Multi-Modal Foundation Models: especially for human-centric perception tasks.
(S-4) Activity Understanding from A Cognitive Perspective: work with multidisciplinary researchers to study how the brain perceives activities.
(E) Human-Robot Interaction (e.g. for Smart Hospital): work with the healthcare team (doctors and engineers) in SJTU to develop intelligent robots to help people.

Projects

HAKE

Human Activity Knowledge Engine•2018•Project Page

Human Activity Knowledge Engine (HAKE) is a knowledge-driven system that aims at enabling intelligent agents to perceive human activities, reason human behavior logics, learn skills from human activities, and interact with objects and environments.

OCL

Object Concept Learning•2022•Project Page

We propose a challenging Object Concept Learning (OCL) task to push the envelope of object understanding. It requires machines to reason out object affordances and simultaneously give the reason: what attributes make an object possess these affordances.

Pangea

Unified Action Semantic Space•2023•Project Page

We design an action semantic space given verb taxonomy hierarchy and covering massive actions. Thus, we can gather multi-modal datasets into a unified database in a unified label system, i.e., bridging “isolated islands” into a “Pangea”. So then, we propose a bidirectional mapping model between physical and semantic space to use Pangea fully.

EgoPCA

EgoPCA: A New Framework for EgoHOI•2023•Project Page

We rethink and propose a new framework as an infrastructure to advance Ego-HOI recognition by Probing, Curation and Adaption (EgoPCA). We contribute comprehensive pre-train sets, balanced test sets and a new baseline, which are complete with a training-finetuning strategy and several new and effective mechanisms and settings to advance further research.

Human-Agent Joint Learning

Robotic Teleoperation, Robot Manipulation, Imitation Learning•2023•Project Page

A human-agent joint learning teleoperation system for faster data collection, less human effort, and efficient robot manipulation skill acquisition.

Video-Distillation

Video Distillation via Static-Dynamic Disentanglement•2023•Project Page

We provide the first systematic study of video distillation and introduce a taxonomy to categorize temporal compression, which motivates our unified framework of disentangling the dynamic and static information in the videos. It first distills the videos into still images as static memory and then compensates the dynamic and motion information with a learnable dynamic memory block.

About

Hi, this is the website of RHOS team at MVIG. We study Human Activity Understanding, Visual Reasoning, and Embodied AI. We are building a knowledge-driven system that enables intelligent agents to perceive human activities, reason human behavior logics, learn skills from human activities, and interact with environment.

Research Interests:

(S) Embodied AI: how to make agents learn skills from humans and interact with human & scene & object.
(S-1) Human Activity Understanding: how to learn and ground complex/ambiguous human activity concepts (body motion, human-object/human/scene interaction) and object concepts from multi-modal information (2D-3D-4D).
(S-2) Visual Reasoning: how to mine, capture, and embed the logics and causal relations from human activities.
(S-3) General Multi-Modal Foundation Models: especially for human-centric perception tasks.
(S-4) Activity Understanding from A Cognitive Perspective: work with multidisciplinary researchers to study how the brain perceives activities.
(E) Human-Robot Interaction (e.g. for Smart Hospital): work with the healthcare team (doctors and engineers) in SJTU to develop intelligent robots to help people.

Human-Agent Joint Learning for Efficient Robot Manipulation Skill Acquisition

MVIG-RHOS, SJTU

demodemodemo
Employing a teleoperation system for gathering demonstrations offers the potential for more efficient learning of robot manipulation. However, teleoperating a robot arm equipped with a dexterous hand or gripper, via a teleoperation system poses significant challenges due to its high dimensionality, complex motions, and differences in physiological structure. In this study, we introduce a novel system for joint learning between human operators and robots, that enables human operators to share control of a robot end-effector with a learned assistive agent, facilitating simultaneous human demonstration collection and robot manipulation teaching. In this setup, as data accumulates, the assistive agent gradually learns. Consequently, less human effort and attention are required, enhancing the efficiency of the data collection process. It also allows the human operator to adjust the control ratio to achieve a trade-off between manual and automated control. We conducted experiments in both simulated environments and physical real-world settings. Through user studies and quantitative evaluations, it is evident that the proposed system could enhance data collection efficiency and reduce the need for human adaptation while ensuring the collected data is of sufficient quality for downstream tasks.

OCL: Object Concept Learning

MVIG-RHOS, SJTU

demo
Understanding objects is a central building block of artificial intelligence, especially for embodied AI. Even though object recognition excels with deep learning, current machines still struggle to learn higher-level knowledge, e.g., what attributes does an object have, what can we do with an object. In this work, we propose a challenging Object Concept Learning (OCL) task to push the envelope of object understanding. It requires machines to reason out object affordances and simultaneously give the reason: what attributes make an object possesses these affordances. To support OCL, we build a densely annotated knowledge base including extensive labels for three levels of object concept: categories, attributes, and affordances, together with their causal relations. By analyzing the causal structure of OCL, we present a strong baseline, Object Concept Reasoning Network (OCRN). It leverages causal intervention and concept instantiation to infer the three levels following their causal relations.

Pangea: Unified Semantic Space for Human Action Understanding

MVIG-RHOS, SJTU

CVPR 2024, Highlight

demo
Action understanding matters and attracts attention. It can be formed as the mapping from the action physical space to the semantic space. Typically, researchers built action datasets according to idiosyncratic choices to define classes and push the envelope of benchmarks respectively. Thus, datasets are incompatible with each other like “Isolated Islands” due to semantic gaps and various class granularities, e.g., do housework in dataset A and wash plate in dataset B. We argue that a more principled semantic space is an urgent need to concentrate the community efforts and enable us to use all datasets together to pursue generalizable action learning. To this end, we design a Poincare action semantic space in view of verb taxonomy hierarchy and covering massive actions. By aligning the classes of previous datasets to our semantic space, we gather (image/video/skeleton/MoCap) datasets into a unified database in a unified label system, i.e., bridging “isolated islands” into a “Pangea”. Accordingly, we propose a bidirectional mapping model between physical and semantic space to fully use Pangea. In extensive experiments, our method shows significant superiority, especially in transfer learning.

Symbol-LLM: Leverage Language Models for Symbolic System in Visual Human Activity Reasoning

MVIG-RHOS, SJTU

demo
Human reasoning can be understood as a cooperation between the intuitive, associative ``System-1'' and the deliberative, logical ``System-2''. For existing System-1-like methods in visual activity understanding, it is crucial to integrate System-2 processing to improve explainability, generalization, and data efficiency. One possible path of activity reasoning is building a symbolic system composed of symbols and rules, where one rule connects multiple symbols, implying human knowledge and reasoning abilities. Previous methods have made progress, but are defective with limited symbols from handcraft and limited rules from visual-based annotations, failing to cover the complex patterns of activities and lacking compositional generalization. To overcome the defects, we propose a new symbolic system with two ideal important properties: broad-coverage symbols and rational rules. Collecting massive human knowledge via manual annotations is expensive to instantiate this symbolic system. Instead, we leverage the recent advancement of LLMs (Large Language Models) as an approximation of the two ideal properties, i.e., Symbols from Large Language Models (Symbol-LLM). Then, given an image, visual contents from the images are extracted and checked as symbols and activity semantics are reasoned out based on rules via fuzzy logic calculation. Our method shows superiority in extensive activity understanding tasks.

Dancing with Still Images: Video Distillation via Static-Dynamic Disentanglement

MVIG-RHOS, SJTU

teaset
Recently, dataset distillation has paved the way towards efficient machine learning, especially for image datasets. However, the distillation for videos, characterized by an exclusive temporal dimension, remains an underexplored domain. In this work, we provide the first systematic study of video distillation and introduce a taxonomy to categorize temporal compression. Our investigation reveals that the temporal information is usually not well learned during distillation, and the temporal dimension of synthetic data contributes little. The observations motivate our unified framework of disentangling the dynamic and static information in the videos. It first distills the videos into still images as static memory and then compensates the dynamic and motion information with a learnable dynamic memory block. Our method achieves state-of-the-art on video datasets at different scales, with notably smaller storage expenditure. Our code will be publicly available.

Method and Results

Overview of our method

demo

The synthetic videos are learned in two stages:
Stage 1: static memory learning with image distillation on one frame per video.
Stage 2: the static (frozen) and dynamic memory are combined.
