Isaac Lab Teleop

isaaclab_teleop integrates the IsaacTeleop retargeting framework with Isaac Lab, providing a single teleoperation device class that manages OpenXR sessions, XR anchor synchronization, retargeting pipelines, and action-tensor generation.

Key Features

  • IsaacTeleopDevice -- unified device that wraps an IsaacTeleop TeleopSession behind a context-manager interface. Returns a flat torch.Tensor action each frame.
  • IsaacTeleopCfg / XrCfg -- declarative configuration for retargeting pipelines, XR anchor placement, rotation modes, and tuning UI.
  • Deferred session creation -- if OpenXR handles are not yet available (e.g. the user has not clicked Start AR), the session is created transparently on the first advance() call once handles appear.
  • Teleop commands -- register callbacks for START, STOP, and RESET commands dispatched via XR controller buttons or the Carbonite message bus.
  • XR anchor rotation modes -- FIXED, FOLLOW_PRIM, FOLLOW_PRIM_SMOOTHED, and CUSTOM modes for controlling how the anchor orientation tracks the reference prim.
  • Retargeting tuning UI -- optional ImGui window for real-time adjustment of retargeter parameters when retargeters_to_tune is provided.

Architecture

IsaacTeleopDevice composes three focused collaborators:

Component Responsibility
XrAnchorManager XR anchor prim setup, dynamic/static synchronization, coordinate-frame transform computation
TeleopSessionLifecycle Pipeline building, OpenXR handle acquisition, session create/destroy, action-tensor extraction
CommandHandler Callback registration and XR message-bus command dispatch

Usage

1. Configure Your Environment

Add an isaac_teleop attribute to your environment config:

from isaaclab_teleop import IsaacTeleopCfg, XrCfg

@configclass
class MyEnvCfg(ManagerBasedRLEnvCfg):
    def __post_init__(self):
        super().__post_init__()

        pipeline, retargeters = my_pipeline_builder()
        self.isaac_teleop = IsaacTeleopCfg(
            xr_cfg=XrCfg(
                anchor_pos=(0.5, 0.0, 0.5),
                anchor_prim_path="{ENV_REGEX_NS}/Robot/base_link",
            ),
            pipeline_builder=lambda: pipeline,
            retargeters_to_tune=lambda: retargeters,
        )

Both pipeline_builder and retargeters_to_tune must be callables (lambdas or functions) because @configclass deep-copies mutable attributes and retargeter objects often contain non-picklable handles.

2. Define a Pipeline Builder

Create a function that builds your IsaacTeleop retargeting pipeline. The builder should return an OutputCombiner with an "action" key containing the flattened action tensor (typically via TensorReorderer). Optionally return a list of retargeters to expose in the tuning UI:

from isaacteleop.retargeting_engine.deviceio_source_nodes import ControllersSource
from isaacteleop.retargeters import (
    GripperRetargeter, Se3AbsRetargeter, TensorReorderer,
)
from isaacteleop.retargeting_engine.interface import OutputCombiner

def my_pipeline_builder():
    controllers = ControllersSource(name="controllers")
    se3 = Se3AbsRetargeter(cfg, name="ee_pose")
    # ... connect retargeters and flatten with TensorReorderer ...
    pipeline = OutputCombiner({"action": reorderer.output("output")})
    return pipeline, [se3]

3. Run Teleoperation

The existing teleop scripts automatically detect isaac_teleop in the environment config:

./isaaclab.sh -p scripts/environments/teleoperation/teleop_se3_agent.py \
    --task My-IsaacTeleop-Env-v0

4. Programmatic Usage

IsaacTeleopDevice supports Python's context-manager protocol:

from isaaclab_teleop import IsaacTeleopCfg, IsaacTeleopDevice

cfg = IsaacTeleopCfg(pipeline_builder=my_pipeline_builder)

with IsaacTeleopDevice(cfg) as device:
    device.add_callback("RESET", env.reset)
    while running:
        action = device.advance()
        if action is not None:
            env.step(action.repeat(num_envs, 1))

advance() returns None while waiting for the OpenXR session, so callers can continue rendering without blocking.

Configuration Reference

IsaacTeleopCfg

Field Type Default Description
xr_cfg XrCfg XrCfg() XR anchor position, rotation, and dynamic-anchoring settings
pipeline_builder Callable[[], OutputCombiner] required Builds the retargeting pipeline
retargeters_to_tune Callable[[], list[BaseRetargeter]] | None None Retargeters to expose in the tuning UI
plugins list[PluginConfig] [] IsaacTeleop plugin configurations
sim_device str "cuda:0" Torch device for output action tensors
retargeting_execution RetargetingExecutionConfig | None None (resolved at session start to mode="pipelined", pacing=DeadlinePacingConfig(safety_margin_s=0.025)) IsaacTeleop retargeting execution settings; deferred so the config imports without isaacteleop
teleoperation_active_default bool False Whether teleoperation is active on session start
app_name str "IsaacLabTeleop" Application name for the IsaacTeleop session

The 25 ms DeadlinePacingConfig safety margin staggers IsaacTeleop's Python work behind Isaac Lab's step Python, giving native work such as rendering time to overlap instead of having both Python stacks contend for the GIL at the start of the step.

XrCfg

Field Type Default Description
anchor_pos tuple[float, float, float] (0, 0, 0) XR anchor position in world frame
anchor_rot tuple[float, float, float, float] (0, 0, 0, 1) XR anchor rotation (quaternion xyzw)
anchor_prim_path str | None None Prim to attach anchor to for dynamic positioning
anchor_rotation_mode XrAnchorRotationMode FIXED How anchor rotation tracks the reference prim
anchor_rotation_smoothing_time float 1.0 Slerp time constant (seconds) for FOLLOW_PRIM_SMOOTHED mode
anchor_rotation_custom_func Callable identity Custom rotation function for CUSTOM mode
near_plane float 0.15 Near clipping plane distance for the XR device
fixed_anchor_height bool True Fix anchor height to initial value of the reference prim

Utilities

  • remove_camera_configs(env_cfg) -- strips camera sensors and their associated observation terms from an environment config. XR does not support additional cameras as they cause rendering conflicts.

Run with Docker

Teleoperation with Isaac Lab runs in a single container. Build the image yourself and run a single container. Do not use Docker Compose for this workflow (no multi-container setup). Everything runs inside one container with Isaac Lab.

Inside the container: install Isaac Teleop once (./isaaclab.sh -p -m pip install 'isaacteleop[retargeters,cloudxr]~=1.0.0' --extra-index-url https://pypi.nvidia.com), then start the CloudXR runtime with --accept-eula so there is no interactive EULA prompt, and run your teleop script. Example:

./isaaclab.sh -p -m isaacteleop.cloudxr --accept-eula &
source ~/.cloudxr/run/cloudxr.env
./isaaclab.sh -p scripts/tools/record_demos.py --task Isaac-PickPlace-Locomanipulation-G1-Abs-v0 --num_demos 5 --dataset_file ./datasets/dataset.hdf5 --xr --visualizer kit

In the Isaac Sim UI, set the AR panel to System OpenXR Runtime and click Start XR. For the full flow and options, see the CloudXR teleoperation how-to and Isaac Teleop Quick Start.

For a fully headless experience, replace --visualizer kit with --headless when running docker and XR teleop session will run automatically.

Dependencies

  • isaaclab -- core Isaac Lab framework
