1. 3D Symmetry Detection under Partial Observation
Goal: develop a 3D symmetry detection method robust to partial observations (occlusion, incomplete scans) and shape deformation (physical damage, noisy scans), then validate it on real 3D shapes captured with an RGBD camera. Building on the lab's work on correspondence-based symmetry detection, the intern will treat symmetry detection as a self-matching problem, using geometry-aware biases such as group-equivariance to handle noisy, incomplete real-world geometry.
Tasks: design/implement the pipeline, train and evaluate on synthetic and real RGBD data, and analyze robustness to occlusion and deformation.
Requirements: systematic programming skills and linear algebra, and basic knowledge of (or interest in) abstract algebra and group theory. Prior 3D vision/deep learning experience is a plus, not required.

2. Robust Robot Action Policies
Goal: Enhance the robustness of robot action policies, such as vision-language-action (VLA) models and world-action models (WAM). Specifically, we explore neural network architectures and training strategies that enable these models to operate robustly against visual input degradation, paraphrasing of natural language commands, and the discrepancy between intended and executed actions. While we investigate individual degradation factors, our ultimate goal is to construct a single, unified model that remains robust across these various types of degradation.
Tasks:
Construct a benchmark to evaluate the robustness of action policy models under realistic degradation scenarios.
Develop solutions tailored to specific types of degradation.
Build a model capable of handling multiple types of degradation.
Conduct experiments using real robot hardware.
Requirements:
Proficient programming skills
Experience in computer vision and deep learning (preferred)

3. Multimodal Memory for AI Agent
Goal: Explore effective memory structures for AI agents, with a primary focus on knowledge graphs. By advancing the text-based knowledge graph construction and utilization techniques developed in our lab, we aim to build a system that automatically constructs and leverages knowledge graphs from multimodal data and AI agents that better utilize such memory structures. This system will then be applied to complex, multi-hop multimodal question-answering and life assistant AI systems.
Tasks:
Develop techniques that construct multimodal knowledge graph autonomously by detecting components within multimodal data and establishing their corresponding relationships.
Build an agent capable of exploring and navigating knowledge graphs effectively.
Apply these systems to question-answering and/or life assistant AI.
Requirements:
Proficient programming skills

4. Adversarial Attacks for Embodied and Physical AI
Goal: Develop embodied and Physical AI systems that can perceive, reason, plan, and act reliably under adversarial attacks and unexpected real-world conditions. The project considers a broad range of systems, including embodied navigation agents, robot manipulation policies, world-model-based agents, and vision-language-action models. We investigate how attacks on sensors, visual observations, language instructions, internal world representations, and action execution propagate through the closed-loop perception–action pipeline.
Tasks:
Construct a benchmark for evaluating adversarial robustness across embodied navigation, robot manipulation, and language-guided control tasks.
Develop attacks targeting different stages of the embodied AI pipeline, including adversarial patches, sensor spoofing, visual prompt injection, corrupted world states, and action-level perturbations.
Analyze how local errors in perception or reasoning propagate into planning failures, incorrect trajectories, and unsafe physical actions.
Requirements:
Proficient programming skills
Basic knowledge of computer vision, deep learning, and linear algebra
Interest in adversarial robustness, embodied AI, or robot learning

5. Dexterous Grasp Generation
Goal: Enable multi-fingered robotic hands to decide how to grasp an object. A grasp that is merely stable is often not the right one. Gripping a knife by the blade holds it firmly but makes it unusable, a grasp designed for a five-fingered hand may be infeasible on a four-fingered one. We therefore study generative models that produce robot grasps conditioned on what the object will be used for (task intent) and which hand is doing the grasping (hand morphology). While we investigate these factors individually, our ultimate goal is to build a single model that handles both together and works on real robot hardware.
Tasks:
Develop task-oriented grasp generation grounded in language or task specifications.
Design morphology-aware representations that generalize across different hand embodiments.
Build a unified model capable of handling both conditioning factors jointly.
Conduct experiments using real robot hardware.
Requirements:
Proficient programming skills
Experience in computer vision and deep learning (preferred)

6. Active Perception for Object Manipulation
Goal: This project studies how a robot can actively move its wrist-mounted camera to a better viewpoint before grasping, rather than relying on a single fixed view. Most existing grasping pipelines assume a single, often fixed RGB-D observation, which frequently leaves target objects partially occluded, leading to inaccurate shape estimation and unstable grasps. From this partial observation, the system reconstructs the scene, selects the next-best camera pose expected to reveal previously occluded regions, moves the arm to acquire this view, and executes a dexterous grasp with a multi-fingered hand using the updated reconstruction. We aim to show that this active, viewpoint-aware strategy improves grasp success rate and robustness compared to single-view baselines, especially for objects with complex geometry and in cluttered scenes.
Tasks:
Build a simulation environment and validate grasp execution using target grasp poses.
Design and implement the perception–action closed loop (reconstruction, next-best-view selection, camera move, grasp).
Train and improve the next-best-view selection policy, and analyze failure cases.
Extend to real robot environments.
Requirements:
Proficient programming skills
Experience in deep learning
Experience with robot simulators (preferred)

7. Robotic Manipulation in Cluttered Environments
Goal: Improve vision-language-action (VLA) models and other robot manipulation policies to operate reliably in realistic, obstacle-rich environments. Existing benchmarks mostly cover simple pick-and-place scenarios; in real-world settings, however, obstacle placements can make the target object inaccessible without interacting with surrounding objects, requiring the robot to reason about such interactions. We aim to build a simulation-based benchmark that evaluates robot policies in such environments across different difficulty levels and use it to analyze failures and improve performance.
Tasks:
Construct a benchmark for robot manipulation in realistic cluttered environments.
Evaluate VLA policies (e.g., OpenVLA, π0.5, GR00T N1.6) and analyze their failures.
Build training data and improve VLA performance through fine-tuning.
Extend to real robot environments.
Requirements:
Proficient programming skills
Experience in deep learning
Experience with robot simulators (preferred)
