Copper is a Rust runtime and SDK for building, running, recording, and deterministically replaying static robot task graphs, from Linux down to bare-metal microcontrollers. It emphasizes zero-allocation realtime execution, compile-time wiring of task graphs declared in RON, and interoperability with ROS 2 via Zenoh.

Use cases

• build a deterministic robot control runtime in rust
• replay recorded robot runs for debugging
• replace ros2 with a faster realtime framework
• run robot software on bare-metal microcontrollers
• simulate a balance bot or flight controller in the browser
• record and inspect robot sensor data offline

When to choose

• you need deterministic, zero-allocation realtime execution for robot task graphs
• you want to record a run and replay it exactly for debugging or testing
• you target hardware from Linux SBCs down to bare-metal MCUs in Rust
• you want progressive migration from ROS 2 via Zenoh interop

When to avoid

• you need a mature ecosystem of off-the-shelf robot drivers and packages like ROS offers
• your team works primarily in C++ or Python rather than Rust
• you need dynamically reconfigurable task graphs at runtime
• you need a quick prototype without learning a new framework
