Tesla's Optimus engineer, Milan Kovac, praised the latest clever hand as a "groundbreaking achievement" and explained that compared to the previous generation's product, this new hand and forearm have twice the degrees of freedom, with 22 degrees of freedom in the hand and 3 in the wrist and forearm. According to Kovac, this video was conducted in real-time via remote operation in the lab, and Tesla plans to manufacture robots with the new clever hand soon.
