armnet-core API Reference¶
armnet_core
¶
Shared wire types for the armnet platform.
Single source of truth for everything that crosses a component boundary (orchestrator HTTP API request/response bodies, NATS message envelopes, runtime SDK return values).
TELEOP_EVENTS
module-attribute
¶
TELEOP_EVENTS = (TELEOP_EVENT_NEXT_EPISODE, TELEOP_EVENT_RERECORD_EPISODE, TELEOP_EVENT_STOP_RECORDING)
TerminalStatus
module-attribute
¶
TerminalStatus = frozenset({JobStatus.SUCCEEDED, JobStatus.FAILED, JobStatus.TIMEOUT, JobStatus.CANCELLED})
CompletionStatus
¶
Bases: NamedTuple
Whether an episode has finished, how it went, and who decided.
bool(status) is status.complete, so a caller that only cares
whether to keep going can use it directly.
scored_by names the judge — an environment's own name when its
instrumentation decided, "operator" for a human verdict, "monitor"
for the automated completion model. Recorded with results so a success rate
can be read knowing what produced it.

Environment
¶
Bases: Protocol
A kind of workcell and the tasks it offers.

tasks
¶
tasks() -> Mapping[str, TaskSpec]
Every task this environment can run, keyed by slug.
Source code in core/src/armnet_core/environment.py
173 174 | |
connect
¶
connect(config: Mapping[str, Any], *, task: Optional[str], report_progress: Optional[Callable[[str], None]] = None) -> Optional[InstrumentedCell]
Open a session, or return None if this cell has no hardware.
config is the cell's environment block, passed through untouched
from its configuration file.

176 177 178 179 180 181 182 183 184 185 186 187 | |
EnvironmentNotFound
¶
Bases: LookupError
Raised when no installed package provides the named environment.
Source code in core/src/armnet_core/environment.py
190 191 | |
InstrumentedCell
¶
Bases: Protocol
A live session against one cell's instrumentation, for one job.
Implementations own everything about their kind of workcell: the transport,
how a task's goal is expressed, and how the scene is restored between
episodes. Job code sees only this interface, through ctx.cell.
No method here may raise because the hardware misbehaved. Instrumentation is an aid to a rollout, never the thing that fails one, so a silent panel reports "nothing known" and lets the operator decide.

instrument
¶
instrument(robot: Any) -> Any
Return robot, wrapped if this environment records alongside it.
The wrapper must not change the observation the policy sees. Readings
belong in a sidecar, not in observation.state, or a policy trained
without the instrumentation will behave differently with it attached.
Source code in core/src/armnet_core/environment.py
111 112 113 114 115 116 117 | |
readings
¶
readings() -> Mapping[str, Reading]
Current value of every channel, empty if nothing has been heard.
Source code in core/src/armnet_core/environment.py
119 120 | |
begin_episode
¶
begin_episode() -> Iterable[str]
Open an episode window and report anything wrong with the scene.
Returns human-readable problems — a goal already satisfied before the rollout starts, say — which make the episode unscorable rather than failed. An empty iterable means the scene is ready.
Source code in core/src/armnet_core/environment.py
122 123 124 125 126 127 128 | |
episode_status
¶
episode_status(*, final: bool = False) -> CompletionStatus
Whether the instrumentation can call this episode yet.
complete=False means "no verdict", whether because the goal is
unmet or because nothing readable bears on it. Callers fall back to
another judge; they cannot distinguish, and should not need to.
final=True says the episode is out of time and asks for a last
word. An unmet goal is then a failure rather than an abstention: an
operator should not be asked to confirm a failure the instrumentation
can see. Channels that read nothing still abstain.

130 131 132 133 134 135 136 137 138 139 140 141 | |
reset_scene
¶
reset_scene(*, confirm: bool, reset_cell: Callable[[bool], None]) -> None
Restore the state this task starts from.
reset_cell returns the arm to rest and, when passed True, waits
for an operator. Implementations decide whether a human is needed;
confirm=True means the caller has already decided one is.
Source code in core/src/armnet_core/environment.py
143 144 145 146 147 148 149 | |
attach_dataset
¶
attach_dataset(dataset_root: Any) -> None

record_frame
¶
record_frame() -> None
Buffer the current readings against the frame just recorded.
Source code in core/src/armnet_core/environment.py

commit_episode
¶
commit_episode(episode_index: int) -> None
Persist buffered readings for a saved episode.
Source code in core/src/armnet_core/environment.py
157 158 | |
discard_episode
¶
discard_episode() -> None
Drop buffered readings for an episode that will not be saved.
Source code in core/src/armnet_core/environment.py
160 161 | |
close
¶
close() -> None
Release the connection.
Source code in core/src/armnet_core/environment.py
163 164 | |
Reading
dataclass
¶
One instrumentation channel's current value.
continuous separates channels that sweep through values as they move,
such as a slider or a dial, from ones that jump between a few states, such
as a switch. Anything watching the instrumentation has to treat those
differently: a switch is worth reporting on every change, while a dial
being turned would otherwise report continuously.

CellStatusSummary
¶
Bases: BaseModel
Aggregate availability for an embodiment, optionally scoped to a task.
Callers ask by task, which is what they think in; the orchestrator
resolves it to the environment that can run it and matches cells on that.
Both are echoed back. task is None when the summary aggregates
across the whole embodiment, which is what a task-less job needs.

¶
traceback: Optional[str] = Field(default=None, description="Python traceback from the customer's `@main`-decorated function if it raised. Extracted by the cell from the `[armnet:traceback]:json` marker line in stdout. Capped at ~64 KiB on the cell side; the full untruncated traceback is also in `stderr` for power users.

raise_for_status
¶
raise_for_status() -> None
Raise :class:RemoteExecutionError iff this result isn't SUCCEEDED.
The httpx-style "opt-in raising" pattern. Use it when you'd rather
bail than branch on result.status::
result = execute(...)
result.raise_for_status()
do_thing(result.return_value)
For successful results this is a no-op.

JobSpec
¶
Bases: BaseModel
The fields a client supplies when creating a job.
This is the body of POST /jobs. The orchestrator wraps it into a
:class:Job (assigning id, status, timestamps) before
persisting.

instance-attribute
¶
username: Optional[str] = Field(default=None, description='Authenticated armnet username. Set by the orchestrator from the API key; clients should not rely on supplied values being preserved.')
JobStatus
¶
Bases: str, Enum
Job lifecycle states.
Mirrors the design doc §3.5 state machine. A job is created SUBMITTED;
if the target cell isn't available it becomes QUEUED (run when the cell
next comes online — the
scheduler is a later phase), otherwise it is DISPATCHED to a cell, then
RUNNING, then a terminal state.

JobStatusTransition
¶
Bases: BaseModel
One entry in a job's status-change audit trail.
Emitted by the orchestrator's GET /jobs/{id}/status-transitions so users
can trace a job's lifecycle. detail carries optional context (e.g. the
cell id on dispatch/run, or the failure message on a terminal state).

RegistryCredentials
¶
Bases: BaseModel
Short-lived credentials for pushing to the platform's image registry.
Returned by POST /registry/credentials. The orchestrator mints
these on demand by impersonating a dedicated image-pusher service
account. Customers never need to know about Google Cloud, IAM, or
service accounts — they just Image.build(...).push().
The password is an OAuth2 access token valid for ~1 hour. The
SDK caches it on disk and refreshes within 5 minutes of expiry.

RemoteExecutionError
¶
Bases: RuntimeError
Raised by :meth:JobResult.raise_for_status for non-succeeded results.
The exception's __str__ includes the underlying status, any
platform-side error, and the user's traceback (if any), so an
unhandled raise prints all the diagnostic context an operator needs.
The original :class:JobResult is available as :attr:result for
structured access.

RobotArmConfig
¶
Bases: BaseModel
Named arm configuration for multi-arm (bimanual) cells.
The runtime derives each arm's connector endpoint from the cell-level
robot_connector_endpoint plus the arm name; port is the physical
serial device that arm is wired to on the edge Pi, used by the Fleet Agent
to provision the (bimanual) edge connector with the per-arm port mapping
(--arm-ports). Optional because the edge can also be provisioned
out-of-band, but set it so the agent can bring a bimanual cell up itself.

RobotCellConfig
¶
Bases: BaseModel
Physical robot cell configuration loaded from robot_cell.json.
This is operator-owned configuration, not job input. The cell and local Docker runner use it to inject the same robot metadata into the runtime context for every job that lands on this cell.
The JSON file may use a nested structure with top-level groups:
cell, robot, data_interface, policy. A model validator
flattens nested input into the canonical flat field set for backward
compatibility with all existing consumers.

TeleopAction
¶
Bases: BaseModel
A single remote-teleoperation action for a running job.
Sent by the client (sampling a local leader arm) to the orchestrator over a
websocket, forwarded to the cell on the job's teleop NATS subject, and kept
by the cell as a most-recent-value register. timestamp (unix seconds, on
the client clock) is used to drop out-of-order/stale messages so the cell
always holds the freshest action.

TeleopEvent
¶
Bases: BaseModel
A discrete recording-control event for a running teleop job.
Travels the same path as :class:TeleopAction (client websocket →
orchestrator → the job's teleop NATS subject → cell), but with different
delivery semantics: actions are a freshest-wins stream where drops are
fine, whereas events are rare, user-initiated commands that the cell queues
in order so none is lost between runtime polls.
The event values mirror LeRobot's dataset-recording keyboard controls:
Right Arrow ends the current episode and moves on (next_episode), Left
Arrow discards and re-records it (rerecord_episode), and Esc stops the
whole session (stop_recording).

environment_for
¶
environment_for(name: str) -> Environment
Load the environment registered under name.
Loading is deferred to here so that importing this module costs nothing: an environment's drivers are only imported by a process that actually intends to talk to one.

task_environment
¶
task_environment(task: Optional[str]) -> Optional[str]
Name the environment that owns task, or None if unowned.
Used where the mapping is needed without a database — chiefly tests and
local runs. The orchestrator resolves through the tasks table instead,
so routing never depends on which environment packages it has installed.

armnet_core.enums
¶
Embodiment, environment and task wire-type aliases.
These are stable string slugs that appear in HTTP bodies, NATS subjects, env
vars injected into customer containers, and cell configuration (for example
"lerobot/so-101", "busybox", "busybox_left_toggle_down").
The three name different things:
Embodiment is the robot — what arms the cell has.
Environment is what the robot is working on: an instrumented BusyBox panel,
a table of wooden blocks. A cell is assigned one, and can then run any task
that environment offers without being reconfigured.
Task is a single job to perform within an environment. Users request a
task; the platform resolves it to an environment to find a cell that can run
it.
Valid embodiments and environments live in the orchestrator's Postgres database
(see db/), which routing treats as the source of truth so it never depends
on which environment packages happen to be installed. Task behaviour — the
goal, how it is scored, how the scene is restored — lives in the environment's
own package, because it is inseparable from that environment's instrumentation.
The database mirrors those tasks for validation and routing.
armnet_core.models
¶
External-facing wire types for the armnet platform.
Customer-touching models only — request/response bodies for the
orchestrator HTTP API and the result payloads embedded in those responses.
Internal NATS message envelopes (JobDispatch, CellHeartbeat) live
in the separate armnet-protocol package alongside the NATS subject
taxonomy.
Keep this module dependency-light (pydantic + stdlib only) so it can be imported from any component without dragging in HTTP or NATS clients.

JobStatus
¶
Bases: str, Enum
Job lifecycle states.
Mirrors the design doc §3.5 state machine. A job is created SUBMITTED;
if the target cell isn't available it becomes QUEUED (run when the cell
next comes online — the
scheduler is a later phase), otherwise it is DISPATCHED to a cell, then
RUNNING, then a terminal state.

RobotArmConfig
¶
Bases: BaseModel
Named arm configuration for multi-arm (bimanual) cells.
The runtime derives each arm's connector endpoint from the cell-level
robot_connector_endpoint plus the arm name; port is the physical
serial device that arm is wired to on the edge Pi, used by the Fleet Agent
to provision the (bimanual) edge connector with the per-arm port mapping
(--arm-ports). Optional because the edge can also be provisioned
out-of-band, but set it so the agent can bring a bimanual cell up itself.

RobotCellConfig
¶
Bases: BaseModel
Physical robot cell configuration loaded from robot_cell.json.
This is operator-owned configuration, not job input. The cell and local Docker runner use it to inject the same robot metadata into the runtime context for every job that lands on this cell.
The JSON file may use a nested structure with top-level groups:
cell, robot, data_interface, policy. A model validator
flattens nested input into the canonical flat field set for backward
compatibility with all existing consumers.
