Generative AI in the Foundation Layer
The Foundation Layer focuses on generating essential resources, such as synthetic data to augment limited datasets and reward signals to guide reinforcement learning, forming the backbone for model training and evaluation.
Data Generation: Generative models like GANs, VAEs, and diffusion models create synthetic data, videos, and annotations, alleviating data scarcity. Simulation-based generation (e.g., PyBullet, MuJoCo) is augmented with domain randomization and generative models (e.g., Gen2Sim, RoboGen) for diverse scenes and demonstrations.
Reward Generation: Vision-Language Models (VLMs) and Large Language Models (LLMs) provide structured supervision and policy scores, densifying sparse rewards and improving task execution. Examples include relabeling demonstrations (e.g., PAFF, Hindsight Experience Replay) and generating reward code (e.g., EUREKA).
Generative AI in the Intermediate Layer
The Intermediate Layer covers tasks like language, code, visual, and state generation, which enable robots to interpret instructions, process sensory data, and reason about their environment, bridging perception and action.
Natural Language Generation: LLMs (e.g., ChatGPT, Claude-3) decompose complex tasks into sub-goals, enabling physically-grounded plans (e.g., SayCan, Grounded Decoding), and leverage external memory (e.g., SayPlan, RoboMP2) for enhanced task planning.
Code Generation: LLMs/Multimodal Large Language Models (MLLMs) directly generate executable robot code (e.g., Code as Policies, RoboScript), facilitate decomposition-based planning (e.g., ProgPrompt, RoboCodeX), and incorporate physical constraints (e.g., VoxPoser, Prolog).
Visual Generation: Video diffusion models (e.g., UniPi, SLOWFAST-VGEN) are used for action planning, image diffusion models (e.g., SuSIE, CoTDiffusion) for subgoal images, and 3D generation (e.g., TAX-Pose, ManiGaussian) for spatial complexity.
State Generation: Generative models learn compact latent representations for observation (e.g., Nair et al., LIV) and dynamics modeling (e.g., Dreamer, ManiGaussian), enabling prediction of future states and transitions.
Generative AI in the Policy Layer
The Policy Layer directly addresses core robotic manipulation problems, including grasp generation and trajectory planning, translating insights from the lower layers into actionable control strategies.
Grasp Generation: Variational Autoencoders (VAEs) (e.g., Mousavian et al., Sundermeyer et al.) generate diverse, physically plausible grasps by learning latent distributions. Diffusion models (e.g., SE(3)-DiF, DexDiffuser) model multi-modal action distributions for precise 6-DOF and dexterous grasps. Other probabilistic models (e.g., UnidexGrasp) also contribute.
Trajectory Generation: Sampling-based methods (e.g., ALOHA, Diffusion Policy) explore feasible solutions from learned distributions. Large pre-trained models (e.g., RT-2, OpenVLA) predict trajectories from high-level inputs, and hybrid approaches (e.g., GenDP, BiKC) combine techniques for robustness.

Case Study: Mobile ALOHA - Learning Bimanual Mobile Manipulation
The Mobile ALOHA project demonstrates how generative models, particularly through low-cost whole-body teleoperation and imitation learning, enable robots to learn complex bimanual mobile manipulation tasks. By leveraging large datasets and advanced policy generation, ALOHA achieves high success rates for intricate tasks like battery insertion and cup opening, showcasing the potential for efficient skill acquisition and robust performance in real-world scenarios. This exemplifies how generative AI bridges the gap between complex human demonstrations and deployable robot policies.
