Physical AI terms with source trails.
Each page explains what the node means, why it matters, and how not to overread it.
models
Models
AI systems that reason about, simulate, or act in the physical world through robots, vehicles, sensors, and control loops.
ModelsWorld foundation modelsModels built to generate, reason about, or predict physical scenes and trajectories for training, testing, or planning.
ModelsVision-language-action modelsModels that connect visual observations and language instructions to robot actions.
ModelsEmbodied reasoningReasoning that accounts for spatial layout, physical affordances, task state, and what an embodied agent can do next.
data
Data
Robot trajectories, observations, actions, labels, task descriptions, and environment metadata used to train or evaluate policies.
DataCross-embodiment dataTraining data collected from multiple robot bodies, sensors, action spaces, and task environments.
DataSynthetic dataGenerated or simulated observations, trajectories, scenes, and annotations used to supplement real robot data.
DataLeRobotAn open-source robotics library and ecosystem focused on robot learning datasets, policies, training, and hardware deployment workflows.
simulation
Simulation
Software environments that approximate physics, sensors, robots, tasks, and environments for training or validation.
SimulationPhysics engineA computational engine for dynamics, contact, constraints, actuation, and other physical interactions.
SimulationDigital twinsStructured digital replicas of robots, spaces, assets, or processes used for simulation and operational reasoning.
SimulationSim-to-real transferThe transfer of policies, perception, or validation results from simulated environments to real hardware.
embodiment
Embodiment
Combining signals from cameras, depth sensors, force sensors, proprioception, IMUs, lidar, or tactile arrays.
EmbodimentState estimationEstimating the current state of the robot, objects, environment, and task from noisy observations.
EmbodimentTactile sensingContact-sensitive sensing used for manipulation, grasping, slip detection, and material interaction.
EmbodimentManipulationPhysical interaction with objects: grasping, pushing, folding, opening, placing, tool use, and deformable-object handling.
EmbodimentLocomotionMoving the robot body through the world: wheels, legs, balance, gait, terrain, and recovery.
EmbodimentHumanoid embodimentRobots with human-like body plans designed to operate in environments shaped for humans.
control
Control
The mapping from robot observations and goals to actions, often learned from demonstrations, reinforcement learning, or model outputs.
ControlMotion planningPlanning feasible paths, trajectories, or action sequences under geometry, dynamics, and task constraints.
ControlControl stackThe lower-level control, timing, safety interlocks, middleware, and execution layers beneath high-level policies.
ControlWhole-body controlCoordinating many joints and contacts so the whole robot body acts coherently.
ControlROS middlewareCommon robotics middleware used to connect sensors, actuators, messages, nodes, tools, and robot software components.
compute
Compute
The compute inside or near the robot that runs perception, policy, planning, safety, and communication workloads.
ComputeInference latencyThe delay between observation, model computation, command generation, and hardware actuation.
ComputeEnergy and thermal budgetThe power, battery, heat, and cooling constraints that bound onboard model size and runtime.
