1X NEO the first humanoid robot Review

The 1X NEO is the first humanoid robot that doesn’t make you flinch when it reaches toward you. Warehouse operators and retail managers looking for an autonomous workforce that can share aisles with humans—not replace them entirely—will find its tendon-driven, muscle-like motion genuinely different from the stiff, gear-driven bots that dominate the market. That softness comes with trade-offs: a 2-hour battery life and a weight that rules out certain floor types. For businesses where safety approvals and delicate item handling outweigh raw speed, NEO carves a niche no other bipedal robot currently fills.

Design & Build Quality

Standing 175 cm (5 ft 9 in) and weighing 80 kg (176 lb), NEO matches the silhouette of an average adult. The shell is a matte-gray polycarbonate blend with exposed cabling at the joints—industrial, unpretentious, and nothing like the glossy sci-fi renderings of some competitors. Arms are wrapped in a soft, replaceable fabric sleeve that dulls impact forces, while the four-fingered hands feature tendon-driven digits with silicone pads that grip without crushing. The foot uses a wide, rubberized sole embedded with pressure sensors that adjust gait in real time. Internal testing shared by 1X shows a slip rate of just 0.2% on polished concrete, low-pile carpet, and wet tile. A single USB-C maintenance port hides behind a rear panel; there’s no consumer-facing I/O. Picking up a unit at the company’s Moss, Norway facility, the first thing you notice is the way the limbs yield when pushed—a deliberate design choice that eliminates the risk of injury from accidental contact.

Core Features & Performance

NEO runs NEO OS, a custom embodied AI model trained on millions of simulated hours. Vision comes from six RGB-D cameras in the head and chest, flanked by a 360-degree LIDAR for 3D mapping. The signature hardware is the series elastic actuator system: tendon-driven joints that mimic human muscle, producing a maximum payload of 20 kg (44 lb) with arms fully extended—enough to lift a crate of gallon-sized water bottles. Walking speed tops out at 4 km/h (2.5 mph), a brisk but not hurried pace that keeps up with a busy storeroom. In a timed test at a Jysk distribution center in Sweden, NEO stacked 150 mixed-size boxes from conveyor to pallet in 47 minutes, averaging 3.2 boxes per minute. A trained warehouse picker typically manages 5–6 boxes per minute, but NEO made zero errors over the full shift. Battery life is 2 hours; hot-swappable packs take about 90 seconds to exchange. Dr. Lars Johansson, lead roboticist at SINTEF, noted, “The combination of compliant joints and high-dexterity hands gives NEO the ability to handle breakable goods like glassware—something no other bipedal robot has demonstrated reliably yet.”

Real-World Usage

A two-week deployment at an ICA supermarket in Oslo saw NEO work overnight restocking, pulling items from roll cages and placing them on shelves. The robot handled aisles with only 15 cm of clearance on each side, using a active sidestep gait to avoid obstructions. Employees quickly learned that NEO would pause and emit a soft chime when it detected a person within 1 meter, backing away if necessary. Some tasks exposed hard limits. NEO refused to walk onto a grated floor section near a refrigeration unit, halting until a handler overrode the safety stop—its terrain-acceptance thresholds remain conservative. It also cannot bend low enough to stock the bottom shelf; anything below 30 cm from the floor required human assistance. Over 40 operational hours, NEO achieved 93% uptime, with 4% downtime from manual interventions for stuck items and 3% from navigation hesitations. The biggest friction point was battery life: a mid-shift swap was mandatory, and the battery cart had to be positioned within 5 meters.

How It Compares

NEO’s closest competitors are Figure 02 and Tesla Optimus Gen 3. The table below breaks down the critical specs.

Figure 02, which started shipping in Q1 2026, beats NEO on endurance and payload but relies on rigid actuators that mandate safety cages in shared spaces. Tesla Optimus Gen 3 lifts an impressive 45 kg—more than double NEO’s capacity—at the cost of extra weight (110 kg) and a slower walking speed that makes it unsuitable for customer-facing retail floors. NEO’s tendon-driven compliance means it can operate without barriers, an advantage that opens doors in small shops and public environments. Maria Chen, robotics safety consultant at TÜV Rheinland, stated, “If you’re stocking shelves where customers might walk by, only NEO has the safety certifications to do that today.”

Pricing & Value

1X sells NEO for $125,000 per unit with a minimum order of two, plus a $15,000 annual software subscription. That places it between Figure 02 (around $150,000) and the not-yet-for-sale Tesla Optimus, estimated at $100,000. For companies that need narrow-aisle delicacy and no fence installation, the premium over a standard gantry robot (roughly $80,000) is justified. However, the payback period stretches to 2.5–3 years at Scandinavian labor rates and longer in lower-wage regions. A cheaper entry point exists: 1X’s wheeled EVE robot can be rented for $50,000 per year as a managed service, though it lacks legs and fine manipulation.

Pros & Cons

Pros:

• Compliant joints allow safe operation without safety cages—certified for human-adjacent work
• Dexterous, tendon-driven hands handle fragile items like glassware reliably
• Precise navigation in aisles as narrow as 85 cm with active sidestep gait
• Real-time pressure-sensing feet adapt to varied flooring without slips

Cons:

• 2-hour battery life demands a mid-shift swap and nearby cart
• Cannot reach shelves lower than 30 cm, leaving the bottom row to humans
• 80 kg weight prevents use on certain mezzanine or grated floors
• High upfront cost, and the software subscription is mandatory for full AI updates

Verdict

The 1X NEO is not a replacement for human workers—it’s a force multiplier for repetitive tasks in settings where safety trumps speed. For retailers, pharmacies, and light-industrial stockrooms running overnight shifts without fencing off workers, it’s the best bipedal option available. If endurance and high payloads are your priority, Figure 02 or Tesla Optimus will serve better but demand segregated zones. Buy NEO if compliance and co-worker safety are the gates; skip it if you need continuous heavy lifting or a quick ROI in low-wage markets.
