Intro to Robot Operating System (ROS)
Robot Operating System (ROS) has revolutionized the world of robotics software. It serves as the foundational layer on which roboticists and engineers build, design, and control robotic systems. This open-source architecture offers middleware, libraries, and tools that cover a wide array of functionalities, including motion planning and computer vision.
An important highlight of ROS is its community support. A vast network of developers actively contributes to its ecosystem, ensuring a rapid development cycle and problem-solving capabilities. In terms of versatility, ROS is highly modular and supports an expansive range of hardware, from small hobbyist kits to industrial machines.
Although initially developed for academic research, ROS is making its way into various industrial sectors like manufacturing, logistics, and healthcare. To spearhead this transition, the ROS Industrial (ROS-I) project was created, featuring a consortium of major industry partners such as Boeing, Lockheed Martin, and Microsoft.
Developments in ROS 2
To keep up with the evolving needs of commercial projects, ROS 2 was launched in 2017 with an array of new features and enhancements. ROS 2 emphasizes real-time communication, scalability, and security. These improvements are particularly beneficial for industrial projects that involve large teams of robots coordinating their actions in real-time. ROS 2 extends the capabilities of ROS that were previously exclusive to expensive, proprietary software.
For example, Optimax, a U.S.-based optics manufacturer, switched from using ROS to ROS 2 for controlling their ABB robotic arm. This upgrade led to significantly smoother arm movements during the polishing phase of their manufacturing process.
Advantages of using Open-source Software in Industry
Open-source technology like ROS brings multiple advantages to industrial robotics. First, there is the issue of cost-effectiveness. Adopting open-source software often reduces the initial outlay, as open-source licenses like BSD and Apache 2.0 permit commercial usage without any associated costs.
Second, open-source software acts as a foundation for innovation. Engineers can build their unique functionalities upon it without having to develop every software component from scratch. This saves considerable time and resources.
Third, the common architecture and standardized hardware interfaces in ROS allow companies to create customized solutions. This is especially beneficial when a company needs to integrate hardware from multiple suppliers or wants to create highly specialized systems.
Considerations when using Open-source Software in Industry
Despite its advantages, open-source software does come with its set of considerations. For example, adopting open-source tools usually carries an ethical and sometimes legal responsibility to contribute back to the community. This could be in the form of bug fixes, new features, or other enhancements. This collaborative requirement may sometimes be at odds with a company’s desire to maintain a competitive edge.
Another concern lies in the reliability and safety of open-source software. Since it is a communal effort, there is always the risk of unvetted code or updates that could compromise the integrity of safety-critical applications.
Conclusion
The integration of open-source software like ROS in industrial robotics offers promising avenues for innovation and efficiency. As the field advances, it is crucial for industry stakeholders to engage with and contribute to the open-source community, thereby fostering a more robust and innovative environment that sets the stage for groundbreaking developments in industrial robotics.
