Left out because at least one manufacturer does not publish a figure: price.
DOBOT Atom
Straight-knee biped humanoid with mass production batches shipping globally. Features ±0.05mm arm repeatability for precision industrial tasks.
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.
