Autonomy Ladder

Why Level II.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyCopes with everyday clutter and frees itself, shown by independent testing.
IIIConditional AutonomyFinishes whole jobs in familiar spaces; struggles at the edges.
To reach Level IIIMost sessions finish without intervention. Rescue is occasional, not routine.
IIAssisted AutonomyThis robot

Fourier GR-1 runs preset routines on its own, and the owner is its recovery system.

Navigation and control

Vision-only (6 RGB cameras + AI 3D mapping); autonomous navigation and obstacle avoidance.
Why this level
- Teleoperation fallback for complex tasks limits the GR-1 to Level II.
- Autonomous scripted walking and reaching qualify as Level II assisted autonomy.
- End-to-end unscripted task completion requires human pilot oversight within the current operating model.

Human Readiness

Not consumer-ready.

One question: what does buying this robot today walk you into? The state is computed from the record, and recomputed daily.

Not consumer-readyThis robot

Fourier GR-1 ships to commercial and research buyers, not to households.

The readiness scale measures household purchase timing, so no tier applies. A consumer version reaching general availability would start the clock.

Pre-Consumer Assessment

How this projection was reached

75of 100

PromisingAt or above 90% of the 87 robots we assess before release

SpeculativeConceptPlausiblePromisingReady

The hatched tail is unreachable by construction. A projection does not publish as a full mark, because the evidence that settles it does not exist yet: whether the thing ships and works in ordinary use. Those 10 points are what shipping has to earn.

Held below its arithmetic86 → 75

Capped at 75: nothing is pre-order ready without a date, a price and regulatory evidence (readiness is 50, below the floor of 60).

The reading

Fourier's established research platform with proven deployment history, but teleoperation dependency caps autonomy. Engineering maturity and safety practices support the institutional track record; the path to consumer availability or full Level III autonomy remains undefined.

Still open

Upgrade path from teleoperated fallback to fully autonomous complex tasks
Dock/charging infrastructure requirements and site integration costs
Long-term joint durability data under continuous industrial operation
Scaling manufacturability beyond the current 100+ units delivered

This is a projection from pre-shipping signals, not a measurement. When the robot ships, the assessment is archived, a first Robovations Score is computed from the field record, and the change is logged on the tracker rather than appearing as a new number.

Common questions

What people actually ask.

5 answered

OperationWhat tasks has the Fourier GR-1 been deployed to in the field?

Documented GR-1 deployments are in Chinese tier-one hospitals and in European automotive factories, both structured environments with on-site technicians. Fourier does not publish task-level detail for either, so the specific duties within them are not established. Rehabilitation work such as gait training and patient spotting belongs to Fourier’s ExoMotus exoskeleton line rather than to the GR-1; no source documents the humanoid performing it, and patient spotting is a load-bearing safety function that would need its own validation.

OperationDoes the GR-1 require teleoperation, or can it run fully autonomous tasks?

Both. Autonomous scripted tasks (walking, reaching to marked positions) run independently; complex multi-step tasks default to teleoperated control by an on-site pilot. This architectural choice keeps Level III+ autonomy out of reach for now.

OperationWhat did Fourier build before the GR-1?

The GR-1 is Fourier’s first humanoid and its first general-purpose platform. The company’s earlier products are rehabilitation and exoskeleton systems, the ArmMotus and ExoMotus lines and RehabHub, shipped commercially since 2017. That clinical heritage is where Fourier’s experience of machines working in direct physical contact with people comes from, and it is the background the GR-1 program was built on.

OperationWhat is the power/charging model for multi-day deployments?

Fourier publishes no battery capacity or runtime figure for the GR-1, and none appears in the launch material or in coverage of the production version. Charging arrangements for multi-day work, including whether packs are swappable on site, are not documented either and have to be established with the supplying distributor before a deployment is planned around them.

OperationIs there a software development kit (SDK) for reprogramming the GR-1?

Yes. Fourier publishes ROS-compatible SDK and simulation tools. Research institutions can write custom task modules and deploy them via the onboard compute stack.
