Humanoid Robot Specs & Models

Robot Specifications Comparison

Side-by-side specs for the major humanoid robots: height, weight, DOF (independent joints), payload, battery life, and target price.

Battery Life Comparison

How many hours each robot can run on one battery charge. Tesla Optimus leads at 10-12 hours; most competitors land at 2-6 hours, which limits unattended factory shifts.

Degrees of Freedom Comparison

Degrees of freedom (DOF) = the number of independently moving joints in the robot. More DOF means more human-like motion and dexterity. 1X NEO leads with 75, Boston Dynamics Atlas has 56, Tesla Optimus 50+; humans have roughly 244 for reference.

Rated Payload vs Robot Mass

Manufacturer-rated payload (kg) against published robot mass. Payload is a datasheet number, not a continuous industrial duty cycle. Galbot is wheeled, not bipedal.

Published Walk Speed

Peak or typical walk speed in km/h as published by the manufacturer. Demo speeds are not shift-long averages. AgiBot A2 at 11.9 km/h is a peak figure.

Payload as a Share of Robot Mass

Rated payload divided by published mass. 1X NEO is the datasheet outlier (25 kg on a 30 kg robot). That ratio is not a measured continuous-duty result.
