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.

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 under 24 hours.

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 in under 24 hours.

What this means in practice

  • — First working module on real hardware in under 24 hours, 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 a shared foundation, each requirement becomes a fork. Each fork adds maintenance surface. ROSA inverts this. Customer configurations are handled at the platform layer. 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 platform-layer 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 layer, adding a new protocol means rewriting parts of the application or maintaining separate codebases per protocol. ROSA handles fieldbus integration at the platform layer. Your application logic is written once and runs regardless of what is underneath. Adding a protocol is a configuration change.

What this means in practice

  • — CAN, Modbus, Profinet, and other fieldbus protocols abstracted at the platform layer
  • — 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 embedded platforms were not designed to be maintained by someone else. ROSA was. Lifecycle management, long-term support, and security patching are built in from the first line of code and handled by 4Rooks for the duration of your product lifecycle.

What this means in practice

  • — Long-term support obligations handled by 4Rooks, not your engineering team
  • — Security and driver updates managed at the platform layer across your full device fleet
  • — New hardware bring-ups handled without disrupting existing products
  • — Fixed support cost for the duration of your product lifecycle
