Mapping a robot's motors like a motor homunculus: Unitree G1's 43 motors closely resemble the distribution of the cerebral cortex

An author mapped the distribution of motor counts across a robot's body parts in the manner of a motor homunculus, finding that the proportions for each body part are similar to those in the human motor cortex. The Unitree G1, equipped with dexterous hands, has 43 motors in total, with the fingers alone accounting for 14 (about one-third), comparable to the roughly one-quarter to one-third share the hands occupy in the human motor cortex.

Part of the event: Unitree G1 motor distribution resembles proportions in the human motor cortex
