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.
