Copper-Rs:机器人实时遥测确定性数字孪生
Copper-Rs: Live Telemetry Deterministic Twins for Robots

Copper 通过确定性流式架构实现了无缝的远程机器人管理。其工作流程是捕获极简输入,并通过受前向纠错(FEC)保护的“Copperlists”进行流式传输。这确保了即使在丢包严重的网络连接下,“Twin Copper”堆栈也能实时解码、重排并修复数据。 如果数据丢失极其严重,系统会利用自愈恢复点将数字孪生与物理机器人瞬间重新同步,确保远程堆栈始终是本地堆栈的完美镜像。用户可以记录标准的确定性文件,或构建自定义遥测仪表板来监控消息、任务状态和错误日志,就如同在本地操作机器人一样。通过将日志系统与本地依赖项解耦,Copper 提供了强大且高保真的远程操作体验。

Let’s follow step by step how this magic happens:


(1)‍ ‍This is your normal copper stack

(2) This is your normal .copper onboard logging system. This becomes optional if you rely fully on this log streaming feature.

(3) You can set the series of minimal inputs to deterministically anything coming downstream of those input.

(4) Copper will stream its copperlists with FEC, it is done by sending after the fact error packet corrections for the past packets.

(5) Twin Copper decode, fix, reorder the stream from the lossy connection based on the redundancy in the protocol

(6) What if really we miss too much? No worries your stack can send recovery points (that are themselves self healing) to jump restart at any point your twin.

(7) Twin Copper stack is now exactly what is running your robot!

(8) You can log a standard .copper deterministic log

(9) You can build a full Telemetry display to expose exactly what is interesting for you operationally to watch: could be messages, task states, error states, even tasks fields or structured logging exactly like any locally running copper!
