If the “small brain” in your robot can fully understand and verify what the “big brain” is doing, why did you build the expensive big brain in the first place?

This is the trap autonomous robotics has been stuck in for a decade…

Copper is entering a new phase with v1.0.0-rc1.
After two years of rapid iteration, we are starting to make explicit compatibility promises and defining the first stable API surface shaped by real-world use.

This is not about being “done”. It is about freezing the right contracts so teams can build with confidence, while keeping room to evolve toward a deterministic, specifiable, and eventually certifiable robotics runtime.

copper-rs v0.15 is out: multithreaded core, deterministic subsystems, and swarm support. We now extend strict determinism beyond a single process to entire distributed robots, replaying systems spanning multiple computers and MCUs as one unified execution with 100% fidelity, and even scaling that to fleets. This release also introduces a parallel runtime (parallel-rt) to push system bandwidth higher with minimal latency impact, plus a high precision scheduler for tighter control of execution cycles. With this, we have effectively checked all roadmap boxes on the path to 1.0. Full details in the release notes.
