Inside 1X's NEO Factory: Robots Building Robots in Hayward

1X Technologies calls it the NEO Factory. At 58,000 square feet with over 200 employees, it's the first vertically integrated humanoid robot manufacturing facility in the United States. And if 1X delivers on its promises, some of the NEOs rolling off this line will be in customers' homes before the year is out.

What Does "Vertically Integrated" Actually Mean?

Most robot companies design a product, then outsource the building. They buy motors from one supplier, batteries from another, sensors from a third, and assemble everything in a contract manufacturer's facility — often in China or Southeast Asia. That's how phones, laptops, and most consumer electronics work.

1X is doing something different. At the Hayward factory, the company builds the critical components in-house:

• Motors (Revo2): Started from a spool of copper, wound into coils, fabricated into stators, and assembled into tendon-driven actuators. 1X has manufactured 17,000 motors since production began.
• Batteries: Aerospace-grade cells with a proprietary Battery Management System sampling at 100 Hz — roughly 100× faster than typical commercial packs. The welding line completes a weld every 500 milliseconds.
• Tendons: Custom-braided from proprietary materials using a decade of materials science R&D.
• Hands: 22-degree-of-freedom hands manufactured on a dedicated production line, with integrated tactile sensing and molded soft "flesh" over structural components.
• Sensors and electronics: Custom motor electronics, stereo fisheye cameras, beam-forming microphones, and Inertial Measurement Units (IMUs) mounted on in-house racks.

The reason this matters isn't just manufacturing coolness. Vertical integration gives 1X three real advantages:

1. Faster iteration. When you control the motor design and the motor manufacturing and the motor electronics, you can improve the whole stack in days instead of negotiating with suppliers for months.
2. Cost control. Middlemen margins disappear. 1X's VP of Manufacturing, Vikram Kothari (previously at SpaceX overseeing Dragon and Starship programs), explicitly positions this as "the lowest-cost hardware" approach.
3. Supply chain resilience. In a geopolitical environment where Chinese-made robotics components face potential U.S. import restrictions, building motors and batteries in California is a strategic hedge.

The Numbers: What 1X Is Actually Promising

Let's separate the milestone from the marketing. Here's what's confirmed:

The 10,000-unit first-year capacity is notable because all of it sold out within five days of pre-orders opening on October 28, 2025. That's real demand — though at $200 refundable deposits, not all pre-order holders will necessarily convert to full purchases.

The 100,000-unit target for end of 2027 is aspirational. 1X says a second factory in San Carlos is planned to come online later in 2026 to help reach that number. But scaling from 10,000 to 100,000 in under two years would be an extraordinary manufacturing ramp, even with vertical integration.

NEO's Specs From Our Database

Here's what the 1X NEO looks like on paper, based on our database:

• Height: 167 cm (5'6")
• Weight: 30 kg (66 lbs)
• Battery life: ~4 hours
• Max speed: ~4 mph
• AI: 1X Embodied Intelligence with proprietary world model (called "Redwood" by third-party sources)
• Sensors: RGB cameras, depth sensors, tactile skin, microphone array
• Status: Pre-order; first shipments planned for 2026

The 30 kg weight is remarkably light for a humanoid — most competitors are 50+ kg. 1X achieves this through its tendon-driven actuation system, which replaces heavy traditional actuators with lightweight cables and compact Revo2 motors. The trade-off is that tendon systems are harder to manufacture at scale, which is exactly why 1X needs a dedicated factory.

From CAD to Walking in One Month

One detail from the factory tour deserves more attention: 1X's New Product Introduction (NPI) line has compressed the time from CAD design to a walking prototype from one year (for the very first NEO) to one month (for the latest revision).

This acceleration comes from co-locating hardware design engineers with manufacturing engineers next to the Machine Park. Designers can go from releasing a CAD file to holding a physical part in hours, test it, find problems, and iterate — all before committing to mass production.

Why this matters for buyers: if you pre-order a NEO, the robot that arrives at your door may be a significantly improved version compared to what existed when you placed the deposit. Rapid iteration cuts both ways — it means better products, but it also means the specifications and capabilities could shift between pre-order and delivery.

"Robots Building Robots": What's Actually Happening on the Line

The headline "robots building robots" is partially true. NEO units are already working on the factory floor, performing tasks like carrying parts, stocking bins, and handling logistics. But this isn't yet a fully autonomous robot-assembled production line. The assembly process still relies heavily on human workers using intelligent tooling and progressive bring-up verification.

What's more accurate is: 1X is using its own products as factory tools while simultaneously manufacturing them. It's a bootstrapping approach — the first NEOs help make the next NEOs, and each generation of improvements makes the factory more efficient.

The assembly line itself is designed around continuous flow rather than traditional departmental batches. Each station receives pre-kitted modules. Functionality is added progressively with in-line verification at every step. Every build is digitally traceable down to individual components and torque values.

The Privacy Question: Expert Mode in Context

No honest article about 1X can ignore the Expert Mode controversy. When NEO encounters a task it can't handle autonomously, a trained 1X operator can remotely take control — seeing through NEO's cameras and guiding it using VR equipment. 1X CEO Bernt Børnich has been blunt: "If you buy this product, it is because you're OK with that social contract."

The factory opening doesn't change the privacy calculus, but it does shift the timeline context. 1X claims full autonomy (no human operators) could arrive sometime in 2026, with 80–90% autonomy by 2027 and 95%+ by 2028. Those are claims, not guarantees. But the vertical integration approach means 1X controls both the hardware and the AI stack — they're not waiting on a third-party model provider to solve the autonomy problem.

For buyers weighing the decision today, the question is whether you're comfortable with the current limited autonomous capability and the Expert Mode privacy trade-off, in exchange for being among the first to own a home humanoid.

How Does 1X Compare to the Competition?

The humanoid robot space is getting crowded. Here's how 1X's factory approach stacks up against companies also pursuing home or near-home deployment:

Figure AI has been doubling production for three consecutive months and recently demonstrated its Helix 02 loading a dishwasher. Figure's focus is commercial deployment first (BMW, commercial kitchens), homes later. They build in the U.S. but rely on a more traditional supply chain.

Unitree is selling the G1 humanoid directly (we covered the AliExpress buying experience) and just opened its first retail store. But Unitree manufactures primarily in China, using a more traditional supply chain model. Their pricing is more aggressive but they lack the vertical integration 1X claims.

Tesla Optimus targets a sub-$20,000 price point but remains primarily a factory tool within Tesla's own facilities, with production timelines that keep shifting outward.

Zeroth M1 is available for pre-order at $2,899 as a sub-$3,000 humanoid — a very different price tier with correspondingly different capabilities.

1X's unique position is the combination of vertical integration, U.S.-based manufacturing, and a direct-to-consumer home robot focus. No other company is doing all three simultaneously.

When Will You Actually Get One?

Here's the honest timeline, based on what 1X has said publicly:

• Some NEOs will ship in 2026. 1X has promised this repeatedly and the factory is now producing units. Current production goes to R&D testing and internal home testing first.
• The 10,000-unit first run is sold out. If you didn't pre-order in October 2025, you're in the waitlist queue.
• San Carlos factory coming online later in 2026 should expand capacity, but 1X hasn't given a specific date for when waitlist orders ship.
• $499/month subscription option may open up additional availability beyond the early access purchases.

The three-month factory build-out is encouraging — it shows 1X can execute on infrastructure quickly. But manufacturing the first 100 robots is a very different challenge from manufacturing the 10,000th. The reliability lab has already accumulated 20 million+ test cycles, which suggests serious stress testing, but real-world home use will surface issues no lab can predict.

What This Means for Home Robotics

The NEO Factory is significant not because of what it produces today, but because of the manufacturing precedent it sets. If 1X can actually scale from 10,000 to 100,000 units while maintaining quality control, it proves that humanoid robots can be manufactured like consumer electronics — not hand-assembled lab prototypes.

The "robots building robots" milestone, even in its current partial form, is the beginning of a compounding loop. Every NEO that works on the factory floor generates training data, improves processes, and helps build the next one faster. If this works, the cost per unit drops with each production run.

For anyone tracking when humanoid robots become real consumer products rather than perpetual demos, a factory in Hayward, California that's actually winding copper into motors and shipping finished robots is a more meaningful milestone than another trade-show video.

The robots are being built. Now we find out if they work.
