Competitors XPeng and Xiaomi Cyberone rapidly copying Tesla Optimus knee joint design, indicating patent enforcement risk and design convergence in humanoid robotics
Elon Musk· Tesla / SpaceX / xAI· Robotics· 2026-05-30· about XPeng, Xiaomi
“The competition is already on Tesla's course. As an X-Peng, in 2025, its humanoid robot of the next generation was introduced from Eisen. Analysts quickly recognized similarities between Knie, architecture and Tesla's optimal system. The construction seemed to be a modified, round-shaped hook and a corresponding connection piece, similar hip configurations to be included.”
Why it matters
Rapid design copying by competitors suggests Tesla's mechanical innovations may face patent challenges or accelerate industry-wide adoption of similar architectures, reducing Tesla's unique advantage.
Investment implication
Patent disputes may arise; however, if Tesla's knee design becomes industry standard, it validates the architecture and may pressure all humanoid robotics makers on cost and complexity, benefiting efficient manufacturers.
