Safety at home and office: 35-70 kg of falling metal, and almost nothing is certified

Applies to: Everyone; decisive for anyone considering a platform humanoid (Unitree, Booster) in a home, school, or open-plan office

The short version

A G1 is 35 kg, an H1 is 47 kg with 360 N-m joints; a fall or flail at head height is a serious injury risk, and an e-stop on a biped causes a fall rather than preventing one. Research humanoids are run on gantries/tethers with clear floor space. ISO 13482 (2014) exists but has no binding test methods; the EU Machinery Regulation 2023/1230 bites from January 20, 2027. No purchasable humanoid is certified safe for unsupervised home use in mid-2026.

The facts

01
Mass and torque numbers: Unitree G1 is about 35 kg with battery; H1 is 180 cm / 47 kg with joints producing up to about 360 N-m (roughly 265 lb-ft); Unitree's own G1 page warns the robot 'has a complex structure and extremely powerful power' and tells users to 'keep a sufficient safe distance', explicitly framing it as a civilian machine whose limitations individuals should understand before buying.
02
The May 2025 viral H1 incident is the canonical example: a tethered H1 at a Chinese facility violently flailed when its balance controller fought the tether force in a feedback loop, nearly striking two technicians (New Atlas, Fox News); the cause was a known failure mode, not 'rogue AI', but the kinetic energy on display is exactly what a bystander would absorb.
03
The e-stop paradox: unlike a fixed industrial arm, you cannot simply cut power to a walking biped, because power loss guarantees an uncontrolled fall and secondary collision; 2026 research (arXiv 'Learning Safe-Stoppability Monitors for Humanoid Robots') formalizes that a humanoid e-stop must execute a controlled fallback behavior rather than a power cut, and this capability is still a research topic, not a shipped feature.
04
Standard lab practice for a reason: humanoids are developed and demonstrated on overhead gantries, hoists, or tethers with cleared floor areas; high-profile demos have used tethers and counterweights out of camera view (Kite Compliance's humanoid field-safety review), and buyers should replicate this: a rolling gantry, a spotter, and a keep-out radius during any untethered operation.
05
Certification reality: ISO 13482 (personal care robots, 2014) is the only home-adjacent standard, and per IEEE Spectrum's May 2026 analysis its ongoing revision still 'does not set limits, propose testing methods, or have enforcement mechanisms'; industrial deployments lean on ISO 10218:2025 and the in-development ISO 25785-1 for legged industrial mobile robots; as of mid-2026 no consumer humanoid on the market advertises third-party certification to ISO 13482.
06
EU-specific: the Machinery Regulation (EU) 2023/1230 replaces the Machinery Directive on January 20, 2027, and explicitly extends CE conformity requirements to autonomous mobile machinery, AI-driven behavior, and cybersecurity; anyone importing a Chinese humanoid into the EU for professional use becomes the 'importer' with CE obligations, and after Jan 2027 conformity must be shown under the new regulation (TUV Rheinland, EU-OSHA).
07
The one robot designed around home safety proves the rule: 1X NEO weighs only 30 kg, uses tendon-driven low-inertia actuation, a soft polymer lattice exterior, and quotes a Head Injury Criterion under 250 (humanoid.guide), an engineering posture no metal-skeleton platform robot (G1, H1, T1) attempts; that is why manufacturers of platform humanoids position them for research/commercial use, not homes.
08
Practical floor rules for an office or lab: minimum 3-4 m clear radius during dynamic motion, hard-surface flooring checks (a 47 kg fall can crack tile and whatever it lands on), physical e-stop within reach plus wireless e-stop on the RC, gantry for early development, no operation around children, and treat stairs and glass walls as exclusion zones; these mirror the hazard list (falls, limb strikes, entrapment) in current safety literature (Automate.org, Kite Compliance).
