Each square represents one hurdle-jumping trial. Astra iterated controller design through repeated physics simulations.

The Shift

Robotics design moves from months to hours

Astra integrates natural-language planning, code generation, CAD design, physics simulation, and iterative refinement into a single autonomous workflow. Engineers specify what they want; the AI builds, tests, and improves the design in simulation before fabrication.
