When to pick which

When to pick Kepler K2 Bumblebee

Select the Kepler K2 Bumblebee for heavy-duty industrial environments, such as automotive assembly lines or large-scale logistics hubs requiring significant material handling. Its 30kg payload capacity is 50% higher than the Optimus, making it the superior choice for transporting heavy crates or operating industrial tools. With 52 degrees of freedom, it offers the high-precision dexterity necessary for complex research and development or intricate assembly tasks that require human-like manipulation. The eight-hour runtime ensures it can complete a standard industrial shift on a single charge, providing a reliable solution for high-volume manufacturing facilities prioritizing mechanical versatility and lifting power.

When to pick Optimus

Opt for the Tesla Optimus in high-speed logistics operations or service-oriented sectors like elder care and household assistance. Its top speed of 2.23 m/s—double that of the Kepler—makes it far more efficient for navigating expansive warehouse floors or large residential facilities quickly. The lighter 57kg chassis reduces safety risks in human-populated environments and improves energy efficiency during locomotion. Choose this platform for large-scale deployments where rapid mobility and integration into autonomous software ecosystems are prioritized. The 3 kWh high-density NMC battery supports high-intensity bursts of activity, making it ideal for time-sensitive tasks and dynamic environments.
