Tesla also recently posted a short clip of what appears to be a prototype of its humanoid robot’s hands. Tesla has nicknamed its humanoid robot Optimus. The brief video Tesla posted on Twitter shows Optimus making a heart sign with its hands. 

The teaser Tesla recently posted shows the company’s progress with the design of Optimus’ hands and hints at the design of the entire robot. The teaser poster of this year’s AI Day also features robot hands—and arms—forming a heart shape. Compared to the AI Day 2022 teaser poster, the hands featured in the video seem more refined.
