ROS_I means ROS Industrial
ROS_I 解决了哪些问题：
1. 让自动化可以互相协作，操纵器、末端执行器、感知系统/传感器，移动平台，周边设备，都可只用一种语言（ROS messages）交流。在无视OEM厂商品牌或者通信总线的情况下，也能协作。
2. 免费的封装模块库，提供了高级能力，最好的技术可以得到传播，绕开了专有厂商的锁定，再培训或价格问题。
3. 为制造自动化软件的开源开发，提供了监管和结构。在这个项目中的代码都是被复审过，并且自动评估质量指标。
4. 为学术研究提供了一个自我审查的渠道，使之可以快速应用到工业中。
Can I develop closed-source software for ROS-I and sell it for profit?
A: Yes! We desire for the ROS-I community to foster all manner of new businesses selling ROS-I compatible software nodes, development tools, GUIs, support and integration services.
Is ROS-Industrial suitable for real-time control?
A: Like ROS, ROS-I nominally runs on Ubuntu Linux, which is not a real-time OS. ROS-I is fast enough to run closed-loop with perception systems for manufacturing automation applications, but (at least for now) ROS-I must be used as a high-level controller in
conjunction with a low-level real-time controller (usually the one from the OEM), which closes servo feedback loops and provides safety behavior (e.g. an E-stop).
