RAI Institute released video of AthenaZero, a 5'3" humanoid prototype with a six-foot wingspan, juggling three balls using only palm-contact feedback — no external cameras or tools. The robot has a one-degree-of-freedom torso, two seven-degree-of-freedom arms, and six-degree-of-freedom hands, demonstrating real-time bimanual coordination at speeds requiring sub-millisecond reaction times. The demo hit 181 upvotes and 37 comments on r/singularity, verified by coverage on Phemex and TechEBlog.
