ROS is a great platform for building robotics software applications, but it can be painful when you have a mix of different operating systems and package dependencies.
A client complained to me
"... it's been a headache lately trying to work with ROS 2 on different operating systems. It seems like every time I try to compile or run our applications on certain platforms, we run into all sorts of issues with missing dependencies, incompatible libraries, or conflicting system configurations. It's like a never-ending cycle of compilation errors, linker failures, and runtime crashes"
Take these steps to break the cycle
Leverage Containerisation Technologies
Utilize containerisation technologies such as Docker to encapsulate ROS 2 nodes along with their dependencies and runtime environments.
Containers encapsulate an application and its dependencies, making it easy to deploy and run the same application consistently across different environments, regardless of the underlying operating system or hardware architecture. This portability simplifies cross-platform development and ensures consistent behavior across diverse deployment targets.
Containers facilitate reproducible builds and deployments by capturing the entire application environment in a portable, immutable artefact. You can version-control container images and track changes to the application's configuration and dependencies over time, ensuring consistency and reliability in software releases.
Cross-Platform Testing
Cross-platform testing ensures that ROS 2 applications behave consistently across different operating systems and hardware architectures. By testing on diverse platforms, you can verify compatibility and identify platform-specific issues early in the development cycle, reducing the risk of runtime errors or deployment failures in production environments.
Establish comprehensive testing procedures that verify cross-platform compatibility of ROS 2 nodes under different operating systems and hardware configurations.
Automated testing frameworks can help identify and address communication issues early in the development cycle, ensuring reliable cross-platform performance.
Platform-Specific Adapters
Develop platform-specific communication adapters or wrappers that encapsulate platform-dependent functionality and expose a unified interface to ROS 2 nodes. By decoupling ROS 2 nodes from platform-specific dependencies and constraints, adapters enhance portability and facilitate deployment on a wide range of operating systems and hardware platforms. You can leverage adapters to bridge the gap between ROS 2 applications and target platforms, enabling cross-platform communication without sacrificing functionality or performance.
Adapters facilitate integration with legacy systems or third-party software components that may have platform-specific requirements or communication protocols. By providing compatibility bridges between ROS 2 and existing systems, adapters enable seamless interoperability and data exchange, allowing organizations to leverage ROS 2 capabilities within their existing infrastructure.
