Industries / Industrial IoT

Bare metal to RTOS in days. Fieldbus variants without fragmenting what you already have.

Industrial product teams face two compounding challenges: getting to a working RTOS-based system fast enough to maintain confidence, and scaling across customer variants and fieldbus protocols without the codebase fragmenting. ROSA is built for both.

Let's talk

The challenge

Why firmware complexity compounds in Industrial IoT

Industrial product families grow in two directions at once. Customer-specific variants multiply the maintenance surface, while the underlying platform ages toward a transition nobody wants to do. The move from bare metal to RTOS is usually the right call. Getting there without months of lost momentum is where most teams struggle.

Quick Prototyping

First working module on your hardware in days, not months.

The decision to move from bare metal to RTOS is usually the right one. The transition is where teams lose months. RTOS expertise is hard to hire, bring-up work is unpredictable, and demonstrators that should take days drag on until leadership starts asking questions. ROSA abstracts the RTOS complexity behind clean, consistent APIs. Your team works with structured node templates and auto-generated interfaces. The first working node on real industrial hardware lands within days, and a capped pilot puts ROSA on your own SoC in one week.

What this means in practice

  • — First working module on real hardware in days, regardless of RTOS
  • — RTOS complexity abstracted behind consistent APIs. Your team does not need to become RTOS specialists.
  • — Auto-generated interfaces eliminate the manual bring-up work that delays most transitions
  • — Built-in HIL testing validates your system as you build it, not after months of integration

Customer Variants

Each customer configuration should cost less than the last.

Industrial product families grow by accumulation. Each customer wants something slightly different: a different fieldbus, a different hardware platform, a different feature set. Without shared modules, each requirement becomes a fork. Each fork adds maintenance surface. ROSA inverts this. Customer-specific requirements are expressed as configuration on shared modules, not as forks. The application logic stays shared. The more configurations you support, the lower the incremental cost of each new one.

What this means in practice

  • — Customer-specific configurations handled through configuration and hardware abstraction, not codebase forks
  • — Application logic shared across all customer variants. One codebase, many configurations.
  • — Each new customer configuration adds less overhead than the last
  • — Maintenance burden stays flat as your customer portfolio grows

Protocol Scaling

Add a fieldbus without touching your application logic.

CAN, Modbus, Profinet, EtherCAT: each fieldbus protocol carries its own integration complexity. Without a shared abstraction, adding a new protocol means rewriting parts of the application or maintaining separate codebases per protocol. ROSA ships fieldbus integration as maintained modules. Your application logic is written once and runs regardless of the fieldbus in play. Adding a protocol is a configuration change.

What this means in practice

  • — CAN, Modbus, Profinet, and other fieldbus protocols arrive as maintained ROSA modules
  • — Application logic runs unchanged across different fieldbus configurations
  • — Adding a new protocol does not require touching product code
  • — Protocol updates managed centrally across your full portfolio

Long-term Support

Industrial equipment runs for a decade. Your platform needs to keep up.

Industrial devices ship with long support commitments. Security patches, driver updates, and hardware bring-ups keep arriving years after the original team has moved on. Most in-house firmware bases were not designed to be maintained by someone else. ROSA was designed for exactly that: 4Rooks keeps the OS base and the shared modules current, secure, and patched for the duration of your product lifecycle.

What this means in practice

  • — The long-term care of the OS base and shared modules sits with 4Rooks, not your engineering team
  • — Security and driver updates made once, centrally, for every device in your fleet
  • — New hardware bring-ups land without disrupting existing products
  • — A predictable maintenance path for the duration of your product lifecycle
