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

Zeroth Bridge runs preset routines on its own, and the owner is its recovery system.
Why this level
- Zeroth lists two control modes: FlowMimic, which replays captured motion such as walking, squatting and backflips, and Tele_Bridge, real-time whole-body teleoperation with VR support.
- Replayed motion plus a teleoperation mode caps the classification at Level II.
- Launch materials describe no end-to-end autonomous task.

Human Readiness

Pre-release.

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

Pre-releaseThis robot

Zeroth Bridge has not shipped to consumers, and a readiness rating is a claim about buying today.

Until consumer shipping starts, the Pre-Release Assessment carries the evaluation; the readiness clock starts at general availability.

PlausibleAt or above 20% of the 101 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.

The reading

Developer biped announced September 2026 with a published joint map, a $3,999 price and an open SDK, from a maker with no documented deliveries. Rechecked October 6, 2026: the store still reads "first batch now open for pre-order for universities, research teams, and developers," Order now, no delivery date.

Still open

Battery capacity, runtime per charge and recharge time
Whether the robot carries any camera or depth sensor for its advertised obstacle avoidance
Whether total weight is about 10 kg or about 13 kg, since Zeroth's page states both
How joints and actuators hold up after repeated falls and backflip routines

Track Record35% of the assessment38

What this asks

Has this maker shipped what it demoed before, on schedule, with the promised capability?

What it rests on

Zeroth's parent, Suzhou Lexiang, was founded in December 2024 and reported 2025 revenue in the tens of millions of yuan without naming what shipped (Sina, Dec 2025). Its M1 debuted at CES 2026 with pre-orders, and Mia's August 31, 2026 review describes M1 as still in reservation.

Engineering35% of the assessment66

What this asks

Are the demonstrated capabilities achievable in shipping form, or do they need breakthroughs not in evidence?

What it rests on

A small biped with 21 actuated joints and 178.6 g actuator modules rated 10 N-m peak is a familiar form, but a new platform for a maker whose earlier M1 is a 49 cm wheel-leg companion. Durability under repeated falls is undocumented.

Demo Match30% of the assessment58

What this asks

What has been shown to work, against what is claimed in marketing.

What it rests on

Robotics Tomorrow and Interesting Engineering repeat Zeroth's list of walking, obstacle avoidance, choreography and backflips from company material; no outlet reports hands-on use. Zeroth's own page gives two different weights.

Common questions

What people actually ask.

6 answered

OperationIs the Zeroth Bridge the same robot as the Bridge Geek Edition?

Coverage uses both names for the same 88 cm, 13 kg robot. Geek Edition is the name on the Chinese JD.com listing reported in launch coverage; Zeroth’s US store lists a single variant, Zeroth Bridge, at $3,999, and its Builder Program post calls that price the Developer Edition early-bird rate.

OwnershipHow much does the Bridge cost?

$3,999 on Zeroth’s US store. In China, launch coverage reports a RMB 12,888 pre-sale price that drops to RMB 8,888 after an 888 yuan deposit.

OperationWhen will first-batch Bridge orders ship?

Zeroth has not said. Rechecked October 6, 2026, its store still describes the first batch as open for pre-order and gives no delivery window.

OperationDoes the Bridge act on its own, or is it teleoperated?

Zeroth lists both control paths: FlowMimic replays captured motion, and Tele_Bridge provides real-time whole-body teleoperation with VR. No autonomous task completion is described, which places it at Level II.

OperationDoes the Bridge have cameras?

Zeroth’s spec sheet lists an IMU, a circular microphone array and capacitive touch sensing, and names no camera. Launch coverage still describes obstacle avoidance, so the perception hardware is unconfirmed.

OperationCan a developer get a Bridge free through the Builder Program?

Launch coverage says the top 200 of 500 shortlisted developers receive complimentary access, while the other 300 get priority purchase access and the SDK.
