Green Harmonic x Tesla (Optimus Harmonic Drive Reducers)

Electric-vehicle and AI company (NASDAQ: TSLA), founded 2003 and headquartered in Austin, Texas, with a physical-AI program spanning three robotics fronts: a [robotaxi ride-hailing service](/models/tesla-robotaxi), the [Optimus](/models/tesla-optimus) humanoid robot, and the forthcoming purpose-built [Cybercab](/models/tesla-cybercab). Robotaxi: Tesla launched robotaxi service in Austin in July 2025 and operates in two markets as of mid-2026: Austin (unsupervised L4 driverless; small active fleet of ~14, of ~42 vehicles registered with the Texas DMV, late May 2026) and the San Francisco Bay Area (supervised L2 under a CPUC TCP permit; ~1,655 vehicles registered with CPUC but only ~9 active as of late May 2026, down from a ~168 peak in January 2026). The active US unsupervised fleet is ~20 (14 Austin / 3 Dallas / 3 Houston) and has declined since a late-2025 / early-2026 peak; registered counts far exceed the active operating fleet. The vehicles are 2026 Model Y cars running Tesla's [Full Self-Driving / Autonomous Driving System](/brains/tesla-fsd-bot). At its Q4 2025 earnings call (January 2026), Tesla announced plans to expand to seven additional US cities (Dallas, Houston, Phoenix, Miami, Orlando, Tampa, Las Vegas) in H1 2026; Dallas and Houston launched in April 2026, while the other five (Phoenix, Miami, Orlando, Tampa, Las Vegas) slipped to 'preparations underway'. The Austin operation carries a [federally-mandated crash-reporting record](/incidents/tesla-robotaxi-austin-nhtsa-crash-record-2025-2026) (17 NHTSA-reported incidents July 2025 to March 2026, including two teleoperator-caused crashes; zero major crashes and no citations per Austin PD), and NHTSA has separately inquired into videos of erratic driving. Optimus: Tesla's humanoid robot, with Gen 3 mass production commencing at the Fremont factory on January 21, 2026. Notably, at the January 2026 earnings call [Musk](/people/elon-musk) admitted that as of then zero Optimus robots were doing 'useful work' in Tesla's factories. Units at Fremont and Giga Texas are in a supervised learning and data-collection phase, not yet performing productive autonomous manufacturing work. Tesla committed $20B+ in 2026 capex toward Optimus, plans to convert its Fremont Model S/X lines to Optimus manufacturing (toward a stated 1-million-unit/year capacity by end-2026), and is constructing a dedicated Giga Texas facility, all production-capacity ambitions, with first productive internal deployment projected for late 2026 to 2027. Cybercab: a purpose-built, steering-wheel-free dedicated robotaxi vehicle, with production expected to begin around April 2026, not yet the deployed service vehicle as of early 2026. Tesla's physical-AI program operates under intense regulatory and public scrutiny, and is notable for the gap between its publicly stated targets and demonstrated results.
