All humanoid robots. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | PrimeBOT T1 | Zeroth Bridge |
|---|---|---|
| Where it operates | ||
| Home / residential | DependsMarketed as a home companion capable of switching to a wheeled form indoors, but no independent home deployment has been documented. | DependsBuilt as a developer and research platform, not a home appliance; it performs no documented household task. |
| Office / retailthey differ | PoorNo commercial deployment, payload rating or service-context documentation exists for the T1 despite its unusual transformable design. | DependsSold to universities, research teams and developers for skill building, not packaged for a commercial service role. |
| Warehouse / factory | PoorThe quadruped stance suggests rough-terrain potential, but no industrial payload, duty-cycle or ruggedization specs have been published. | PoorNo ingress rating or industrial payload spec; a 2 kg two-finger grip suits bench work, not factory duty. |
| Primary tasks | ||
| Household chores | PoorNo manipulation or chore-completion capability is documented; the T1's published capability is the quadruped-to-wheeled transformation itself. | PoorBuilt-in skills are walking, squatting, dancing and backflips; no household or workplace chore is documented. |
| Social / care | DependsPositioned as a companion machine, but independent verification of conversational or social-interaction capability beyond the transformation demo is absent. | DependsCarries a microphone array and touch sensing but no documented conversational or companion software ships with it. |
| Specialized jobthey differ | PoorNo specialized task capability such as delivery or monitoring is documented beyond the demonstrated form-changing mechanism. | GoodA published joint map, open SDK and VR teleoperation suit specialized locomotion and manipulation research. |
| Supervision needs | ||
| Fully autonomous | PoorNo autonomous, unsupervised task completion is documented; the transformation itself is described as a commanded action. | PoorNo autonomous task completion is documented; it cannot be left to run a job unattended. |
| With oversight | DependsCommanded transformation between quadruped and wheeled-humanoid forms fits an owner actively directing or observing the robot. | DependsFall recovery is undocumented for a 13 kg biped doing backflips; keep a person watching and the area clear. |
| Teleoperated | GoodThe demonstrated transformation mechanism suits an early tester evaluating the robot as a supervised, experimental unit. | GoodTele_Bridge provides real-time whole-body VR teleoperation, the robot's intended hands-on operating mode. |
| Timeline | ||
| Ready today | PoorNot shipping; pre-order windows opened in China on 24 Aug and 3 Sep 2026 with no delivery date confirmed. | PoorAnnounced September 2026 as a first-batch pre-order with no delivery date; no delivered unit is documented. |
| Near-term (1–2 yrs) | DependsA near-term buyer should expect the transformation mechanism's durability and support terms to still be unsettled at delivery. | DependsBeta SDK and simulation access opened September 2026, but hardware ship timing is still unstated. |
| Research phase | GoodFits an interest in monitoring novel transformable humanoid mechanisms more than a purchase decision made today. | GoodPositioned as an open research and development biped, which is the maturity stage it genuinely occupies. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
How much the claim can be trusted.
None of these has shipped, so they are assessed on track record, engineering plausibility and how the demonstrations match the claims.

How far apart is a long way?
A number only means something next to the spread it sits in. Each track 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.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
PrimeBOT T1
The transformation mechanism is demonstrated, but pre-order buyers commit before its durability over repeated cycles has been independently tested.
A pre-order date is not a shipping date, and PrimeBOT has not shown the T1 completing a task without a script.
Zeroth Bridge
$3,999 buys a biped with a published joint map and no published runtime.
Because control is replayed motion or live teleoperation, every new behavior is something a developer has to build.
Two weights on one page: about 10 kg in the header, about 13 kg in the spec table.
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.
PrimeBOT T1
- Buyers needing a confirmed price today
- No verified MSRP or price range has been published for the T1 in China or elsewhere, so a cost-based purchase decision cannot yet be made.
- Households wanting proven daily task automation
- No independent source documents the T1 completing chores or specialized tasks end to end; the confirmed capability is the form-changing mechanism, not task work.
- Buyers outside mainland China wanting an import or support path
- Availability, shipping and support outside China are undocumented; buyers relying on an international purchase or warranty path have no confirmed option today.
- Anyone requiring durability data on the transformation mechanism
- No independent testing of the quadruped-to-wheeled-humanoid transition over repeated cycles has been published, so its long-term mechanical reliability is unverified.
- Anyone requiring an established manufacturer track record
- PrimeBOT's (Qiyuan's) prior shipped consumer-robotics history could not be verified from available sourcing, so buyers who weigh manufacturer reliability heavily should wait for more evidence.
Zeroth Bridge
- Households expecting a robot that does chores
- Launch materials list walking, squatting, dancing, backflips and obstacle avoidance as its built-in skills. None of the sources reviewed describes a household task such as tidying, fetching or laundry.
- Buyers who need a firm delivery date
- Zeroth's store calls the first batch a pre-order and names no ship window. Chinese coverage reports 1,000 JD.com units booked within a week without stating when they deliver.
- Anyone wanting unattended operation around people or pets
- Control runs through replayed motion or live teleoperation, and no fall-recovery or emergency-stop behavior is documented for a 13 kg machine that performs backflips.
- Projects that need camera-based perception out of the box
- The sensor list names an IMU, a circular microphone array and capacitive touch sensing and does not list a camera, although obstacle avoidance is advertised. Confirm the perception hardware before planning vision work.
- Manipulation work needing heavy payloads or dexterous hands
- The end effector is a two-finger gripper rated for 2 kg, on arms reaching 30 to 40 cm, which limits the platform to light, simple grasps.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
PrimeBOT T1
- Daily: Recharge before use; PrimeBOT has not published runtime or charge-time figures for the T1.
- Weekly: Inspect the transformation joints and wheel/leg interfaces for debris or wear after switching forms.
- Monthly: Check for firmware or app updates; PrimeBOT has not published an update cadence for the T1.
- Every 3-6 months: Inspect actuators involved in the quadruped-to-wheeled-humanoid transition for wear from repeated cycles.
- As needed: Recalibrate sensors or restore companion settings after a reset; the recalibration procedure is not documented.
Zeroth Bridge
- After every use: Recharge the pack; Zeroth lists a 12.6 V, 3.2 A charging input but no runtime or charge time.
- After every use: Clear a flat area before walking or acrobatic routines, since fall recovery is undocumented.
- As needed: Update the OpenBridge SDK and robot firmware as Zeroth releases builds.
- As needed: Inspect joints and two-finger grippers after falls or backflips; no inspection interval is published.
- As needed: Keep operation within the 0-40 C range Zeroth lists.
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.
| Robot | Evidence status | Sources reviewed | Last assessed |
|---|---|---|---|
| PrimeBOT T1 | Pre-Release | 3 | Sep 2026 |
| Zeroth Bridge | Pre-Release | 6 | Oct 2026 |
Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
