Editorial analysis
Configurations explain much of the spread
The dataset separates standard Unitree G1 from its maximum EDU configuration. It also keeps basic, gripper and dexterous-hand versions of Booster T1 in separate rows. These are hardware choices rather than revisions to one universal count.
Count active joints on the same basis
A hand can contribute many joints while a mobile or upper-body platform has no articulated legs. Passive movement, coupled joints and independently driven axes should not be silently mixed. The total and body-region fields must be read together.
More articulation is not a task score
Extra joints can expand posture options, but the table does not measure control accuracy, actuator load or task success. Select a configuration using the motions required by the application. A high total alone does not show that a robot can grasp a particular object or recover reliably.
