Nori A3 · Tesla Optimus Gen 2

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

Manual

One action, on command

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.

Not compared, because fewer than two of these robots carry a published figure: Price, Suction, Runtime, Charge time, Noise, Weight.

04 Ownership

What the numbers leave out.

The trade-off

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

Nori A3

At $1,688 you get the hardware; the chores are a project you record yourself.

Off-board inference keeps the onboard computer at Raspberry Pi 5 cost, which makes the home network part of the robot.

Tesla Optimus Gen 2

Vertical integration gives Tesla unmatched manufacturing leverage, but public evidence cannot yet separate autonomous capability from teleoperated demonstration.

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.

Nori A3

Households wanting chores done on delivery: No independent source documents which tasks work when the robot arrives, and Nori's own paper reports no measured task performance. Routines are recorded as demonstrations first.
Multi-level homes needing help on more than one floor: The base is wheeled and differentially driven. Nothing in Nori's documentation describes stair climbing, so a second floor means carrying a 20.4 kg robot.
Homes with unreliable internet or no appetite for off-board processing: Policy inference runs on an off-board backend, and Nori's paper names network connectivity as a requirement. Without it, the onboard Raspberry Pi 5 has no learned behavior to run.
Tasks involving heavy items held in the grippers: The 55 kg rating belongs to the lift column. Each arm is rated for 1.5 kg, which limits handling to light household objects.
Buyers who need warranty terms and a support record: Y Combinator lists Nori Robotics as founded in 2026 with five people, and the order page states no warranty or return terms.

Tesla Optimus Gen 2

Consumer or residential deployment: Tesla has not announced consumer pricing or availability for any Optimus generation. No retail path exists.
Commercial service robotics (hospitality, delivery, logistics): Optimus Gen 2 is not positioned as a commercial service platform. Task-specific performance and real-world reliability are undocumented.
Autonomous operation without remote pilot oversight: Extent of human-in-the-loop requirements and teleop fallback is not publicly detailed. Field operation liabilities are unaddressed.

What stays your job

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

Nori A3

Daily: Recharge the battery, which Nori rates for 6 to 8 hours of operation.
As needed: Record new demonstrations in Nori Lab to add or retrain a task.
As needed: Restart work after the thermal interlock disables the motor bus at 138°F.
As needed: Replace broken parts using the replacement CAD Nori supplies.
As needed: Take backend policy updates, which reach deployed units without a hardware change.
As needed: Clean the lidar window and four camera lenses when perception inputs look obstructed.

Tesla Optimus Gen 2

As needed: No service program exists; Optimus operates only inside Tesla facilities with internal engineering support, and no maintenance documentation of any kind has been published.
As needed: Battery charging and pack management are internal to Tesla; capacity, charge time, and pack service life are unpublished.
As needed: Actuator and joint service falls to Tesla engineering; the Gen 2 hands and limbs have no published wear or replacement data.
As needed: Software and behavior model updates are pushed internally; no public firmware changelog exists.
As needed: No parts catalog, consumable list, or owner procedure exists; there is nothing an owner could schedule.

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.
