Verdict
Atlas (Electric Humanoid) leads on 3 of the 3 weighted dimensions both makers disclose.
Atlas (Electric Humanoid) leads on degrees of freedom (56 vs 43), payload (50 kg instantaneous, 30 kg sustained vs About 3 kg per arm) and battery life (4 h vs 3 h).
Left out because at least one manufacturer does not publish a figure: price and max speed.
Atlas (Electric Humanoid)
Boston Dynamics' fully electric production humanoid, unveiled Jan 5, 2026. Built for industrial material handling, with autonomous battery swapping and a 360° camera view. The company has not published a price or a top speed.
Fourier GR-3
Fourier's first “care-bot” humanoid, designed for interactive companionship with soft covering materials and a moderate height. About 71 kg and 164 cm, with a hot-swappable battery and about 3 h runtime per Fourier's developer documentation.
