Episode notes
Humanlike Forearm-Driven Hands Enable Extreme Dexterity
- Tesla Optimus Gen 3 mimics human biomechanics with 22 degrees of freedom in the hands for extreme dexterity.
- Fifty custom actuators sit in the forearms and use high-tension cables like tendons so fingers remain slim and agile.
Precision Sensing And Micro Cooling Enable Reliable Fine Manipulation
- Internal sensors give force sensitivity of 0.1 newtons and 0.05° joint accuracy for delicate manipulation.
- Micro-cooling channels thinner than a human hair circulate liquid coolant to manage heat from high-precision motors during continuous use.
Unified Multimodal Neural Chip Replaces Manual Motion Programming
- A unified neural network on a custom chip performs multimodal fusion of vision, touch, audio, and balance for ultra-low latency decisions.
- This architecture lets the robot react fluidly without manual line-by-line programming of movements.
