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-2 runs preset routines on its own, and the owner is its recovery system.
What it does on its own
- Bipedal walking demonstrated at launch, with a published maximum of 5 km/h (3.1 mph)
- Dual anthropomorphic arms with 7 DOF per side, ending in twelve-DOF dexterous hands
- Six array-type tactile sensors per hand detect force, identify an object's material and shape, and adjust grip in real time
- Single-arm load capacity of 3 kg (6.6 lb)
- FSA 2.0 actuators rated above 380 Nm peak torque
Why this level
- Fourier GR-2 is a 175 cm biped that walks at up to 5 km/h, carrying its perception and compute onboard rather than depending on a tethered controller, so locomotion is not what limits its placement.
- Task autonomy is.
- Work is set up as programmed task scripts or run under remote operation in controlled settings, and independent task selection or re-sequencing without that supervision is not documented.
- That dependence, not the platform's ability to move, is what holds it at Level II.
What holds it at Level II
- Demonstrated work is operator-directed or pre-programmed. Autonomous task selection is not documented.
- Perception and control run onboard, on a 14-core Intel Core i7 base platform under Ubuntu 20.04, so the platform does not depend on external infrastructure to perceive. What that stack has been shown doing is manipulation within a prepared area.
- Walking is demonstrated at up to 5 km/h on flat flooring; autonomous navigation of an unmapped environment is not.
- Stairs and uneven terrain are undocumented.
- Roughly 120 minutes of runtime means an operator is in the loop at least once every two hours to swap a pack.

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-2 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 arithmetic85 → 75

Capped at 75: nothing is pre-order ready without a date, a price and regulatory evidence (readiness is 35, below the floor of 60).

The reading

Plausible dual-arm platform with demonstrated factory dexterity. Fourier's track record in humanoid robotics mitigates engineering risk; the industrial-only positioning and absent consumer timeline are the primary uncertainties. Whether the platform ever scales beyond pilot deployments will determine readiness for broader markets.

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.

6 answered

OperationDoes the GR-2 operate without a human supervisor or teleoperator?

Not in published deployments. The platform executes pre-programmed task sequences or accepts remote-pilot control in structured factory settings. Autonomous perception and decision-making capabilities are not documented.

OperationWhat are the arm payload and grip strength specifications?

Fourier publishes a single-arm load capacity of 3 kg (6.6 lb). A combined dual-arm figure does not appear in the published specifications. Grip is regulated by the six tactile arrays in each hand, which read force and material and adjust in real time rather than applying a fixed clamping force.

OperationCan the GR-2 climb stairs or operate on uneven surfaces?

Not demonstrated. The GR-2 walks, and Fourier showed it walking at the September 2024 launch with a published maximum of 5 km/h, but the demonstrations are on flat flooring. Stair climbing and uneven-terrain locomotion do not appear in Fourier’s published material.

OperationWhat is the sensor suite for object detection and environmental awareness?

The published detail is on touch: each hand carries six array-type tactile sensors that read force, identify an object’s material and shape, and adjust grip in real time. Perception and control run onboard, on a 14-core Intel Core i7 base platform under Ubuntu 20.04, with a higher-performance compute module offered as an option. Fourier’s launch material details the tactile array rather than the vision and ranging hardware.

OperationWhen will consumer pricing and availability be announced?

No official timeline has been disclosed. The platform remains positioned as an industrial research and pilot offering.

OperationHow long does a fully charged unit operate before requiring recharge?

Fourier’s support documentation gives a 950 Wh pack, about 120 minutes of runtime and about 120 minutes to recharge. The pack is detachable and hot-swappable, so a unit with spares on hand is not held to the two hour limit.
