Modernizing Legacy Systems: A Strategic Imperative for Robotics OEMs

For numerous Robotics Original Equipment Manufacturers (OEMs), legacy systems—dated firmware, monolithic software designs, and aged hardware dependencies—are slowing progress down. These legacy systems, which used to support the foundation of robotic platforms, are now challenges.

The pressure of modernizing legacy systems and integrating scalable, future-ready architectures has never been greater. If you work for a machine or robot builder OEM, or if you're a manufacturer with machines and/or robots in your facility, then the subject of automation system obsolescence will arise sooner or later.

Modernizing Legacy Systems in Robotic OEM

When modernizing legacy systems, robotics OEMs typically face three choices: fully replace the old system for long-term gains or extend its life temporarily with patchwork fixes. Each path comes with trade-offs in cost, downtime, and sustainability. There is a third option, which is to retrofit part of the automation system with new components while keeping other parts in place.

But here’s the good news: Modernizing legacy systems isn’t about abandoning what’s worked in the past. It’s about keeping what still works and adding what’s needed to stay current and competitive. Modernizing means making your existing systems smarter, faster, and ready for what’s next.

Why Legacy Systems Are Holding Back Robotics OEMs

Firmware and embedded systems are central to any robotics platform.  These legacy systems have difficulty responding to the expanding demand for improved intelligence, connectivity, and security.  As a result, many robotics OEMs face significant challenges in modernizing legacy systems to support next-generation capabilities.

1. Slow Innovation: Proprietary platforms and old firmware hinder the integration of new technologies, preventing you from adding cutting-edge features or responding to client requests.

2. Security Risks: Your products are at risk if you fail to adopt robust security features such as encrypted communication and secure booting.

3. Limited Scalability: When it comes to growing operations or adding new features, older systems are ill-equipped to manage the complexity of today's robots.

4. Integration Problems: Most of the time, legacy systems can't connect to modern cloud-based or Internet of Things systems, which renders remote monitoring and data-driven decision-making tricky.

For robotics OEMs, continuing to rely on antiquated technologies is like to running a sophisticated operation on obsolete software. It makes it more difficult to innovate and also increases the maintenance expenses.

Modernizing Legacy Systems: What It Means

Modernizing legacy systems involves upgrading outdated software, infrastructure, and applications to meet current business demands. This process integrates legacy data with new technology to enhance effectiveness, efficiency, and scalability. For robotics OEMs, modernizing legacy systems ensures that platforms stay secure, intelligent, and adaptable to future needs.

1. Refactoring Firmware for Modularity: The first step in modernizing your robotics platform is refactoring old firmware. Older systems are typically monolithic, which means they are huge, stiff, and difficult to maintain. By restructuring this firmware into modular components, you can increase flexibility, accelerate feature development, and simplify update management.

2. Upgrading to Modern RTOS: Many older robotics systems rely on bespoke or out-of-date real-time operating systems (RTOS), which lack the necessary scalability. Upgrading to a contemporary RTOS improves memory management, job scheduling, and interaction with other technologies, such as AI and edge computing.

3. Hardware Abstraction Layers implementation: Most robotics OEMs face the challenge of tightly coupled hardware and software, which makes it hard to add new sensors, actuators, or CPUs. Hardware abstraction layers (HAL) provide a layer of decoupling, enabling your program to communicate with many hardware pieces without needing large rewrites. This makes your platform more flexible and future-proof.

4. Support Secure OTA Updates: The need for secure, real-time firmware updates is critical in robotics, as legacy systems often lack safe upgrade paths and live monitoring. Regami Over The Air (ROTA) enables encrypted bootloaders and secure OTA updates, keeping platforms protected without downtime.

The Strategic Advantage of Modernizing Legacy Systems

For robotics OEMs, the question is not if modernization is needed but when it will deliver the greatest return. Here are several reasons why now is the right time to act:

1. Extend the Product Lifecycle: Rather than rushing to reinvent hardware, a well-executed modernization approach may extend the life of your current items. This is especially important for OEMs that have invested considerably in their hardware platforms. Modernization revitalizes outdated systems, allowing them to grow, integrate, and meet new requirements without a complete rebuild.

2. Enable continuous innovation: Modernized systems provide a strong platform for ongoing innovation. With safe OTA updates and modular software, you can roll out new features, increase security, and boost performance without requiring severe downtime or disrupting the production process. This ensures that your robotics systems remain cutting-edge, offering value to consumers without the need to start from scratch.

3. Open up new sources of revenue: New technologies provide new business models like subscription, remote diagnosis, and data insight. These additional offerings can significantly raise revenue and keep you ahead of your competition that is relying on outdated technology.

4. Comply with all regulatory and compliance requirements: Regulations controlling data privacy, security, and safety requirements change in parallel with the robotics sector. Legacy systems lacking compliance capabilities jeopardize your goods and reputation. Modernization guarantees that your systems satisfy current and future regulatory standards.  

It’s time to move beyond patchwork solutions. Let Regami 's Digital Engineering services help you modernize and transform your systems for the future.
