Fourier GR-1 · Leju Kuavo 5

All humanoid robots. Every measure below is plotted against the full class, so a difference can be read against how much the class itself varies.

01 Classification

What each one does on its own.

The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.

Generalized

Any task, any setting

Environmental

Handles new obstacles without help

III

Conditional

Finishes familiar jobs on its own

Assisted

Runs preset routines, needs rescue

02 Assessment

Where they actually differ.

The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

None of these robots carries a scored assessment yet, so there is nothing to plot here. The classification and evidence below still apply.

03 Measured against the class

How far apart is a long way?

A number only means something next to the spread it sits in. Each track below is the real range across every classified robot in the class, with the median marked.

These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.

04 Ownership

What the numbers leave out.

The trade-off

What each design gives up to be good at what it is good at.

Fourier GR-1

GR-1 walks and reaches to a marked position on its own; any task beyond that defaults to a human teleoperator.

Documented deployments name Chinese hospitals and European auto plants as sites, not tasks: Fourier publishes no task-level detail for either program.

No published battery capacity or runtime figure exists for the GR-1, so planning a multi-day deployment depends on terms set by the distributor, not Fourier.

Fourier’s decade of rehab-robotics experience explains why the GR-1 was engineered for safe human proximity, but gait training and patient spotting belong to the ExoMotus exoskeleton line, not to any documented GR-1 task.

Leju Kuavo 5

Swappable legs, wheels and hands make one platform fit many jobs; none of those jobs has a published result yet.

Who each one is wrong for

Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.

Fourier GR-1

Consumers or small-business owners seeking autonomous help at home: Fourier publishes no GR-1 price; distributors list it quote-only, with both purchase and lease paths. The platform requires on-site integration and dedicated technician availability, and no consumer support ecosystem exists.
Environments without continuous supervision and safety protocols: Teleoperation fallback is mandatory for complex tasks; unattended operation is not supported or recommended.
Applications requiring instantaneous generalization across novel environments: Operates within structured, pre-programmed task domains. Manual task scripting and environment reconfiguration required between deployments.

Leju Kuavo 5

Buyers who need a published price before committing: Leju has not publicly revealed pricing for Kuavo 5, and no quote or channel appears in the sources reviewed.
Households wanting a home robot now: Home services appear only as an application area on Leju's page; no home deployment, price or consumer channel exists.
Operators requiring documented unsupervised task completion: No success rates or autonomy results are published for Kuavo 5's factory demonstrations.
Procurement teams needing a firm delivery date: No delivery or availability date is published, and humanoid.guide lists Kuavo 5 as a prototype not yet for sale.

What stays your job

The upkeep ownership hands back to you, whatever the autonomy level says.

Fourier GR-1

Daily: Battery charge cycle check and dock connectivity verification.
Weekly: Joint range-of-motion inspection on shoulders, elbows, hips, knees for actuator play or grinding noise.
Monthly: Filter cleaning on cooling system (if deployed in dusty environments); sensor lens wipe on cameras and depth sensors.
Every 3-6 months: Firmware update review and installation by technician.
Annually: Full system calibration and load testing.
As needed: Emergency manual override procedures if autonomous motion stalls.
Service terms: Fourier publishes no lubrication interval, wear-replacement schedule or service pricing for the GR-1’s integrated FSA actuator modules. Those terms come from the supplying distributor and should be established before a deployment is budgeted.

Leju Kuavo 5

As needed: Leju publishes no owner maintenance schedule for Kuavo 5, which has no published price or sale channel.

05 Evidence

How much each of these is standing on.

Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
