“…Support staff deeply familiar with networking and web technologies are already in place at most research laboratories and teaching institutions. While prior work has introduced web technology into laboratories [4][5][6][7][8], these have lacked the comprehensive standardization required for true interoperability. Recently, however W3C, the primary international standards organization for the open web, have moved to standardise the Web of Things, with solid industry and community support [9].…”

We present the OpenFlexure Microscope software stack which provides computer control of our open source motorised microscope. Our diverse community of users needs both graphical and script-based interfaces. We split the control code into client and server applications interfaced via a web API conforming to the W3C Web of Things standard. A graphical interface is viewed either in a web browser or in our cross-platform Electron application, and gives basic interactive control including common operations such as Z stack acquisition and tiled scanning. Automated control is possible from Python and M atlab , or any language that supports HTTP requests. Network control makes the software stack more robust, allows multiple microscopes to be controlled by one computer, and facilitates sharing of equipment. Graphical and script-based clients can run simultaneously, making it easier to monitor ongoing experiments. We have included an extension mechanism to add functionality, for example controlling additional hardware components or adding automation routines. Using a Web of Things approach has resulted in a user-friendly and extremely versatile software control solution for the OpenFlexure Microscope, and we believe this approach could be generalized in the future to make automated experiments involving several instruments much easier to implement.

A service oriented architecture for simultaneous access in the field of remote labs has been proposed and validated using stress load testing. The innovation of this work lies on the use of the parameters collected for the typical student and tested with the Artillery.io tool. Then, we have evaluated the performance of the laboratory by defining 5s the maximum waiting time that a request cannot be exceeded. This article also describes a use case showing how this architecture was designed and developed with 109 students.

Automated and computerised control of scientific instrumentation is almost ubiquitous in the modern laboratory. Most instrumentation is controlled over decades old communication busses or is accessed via proprietary system libraries. This limits which languages and operating systems can be used to control instruments, and poses a significant problem when interfacing multiple instruments into the same experiment. Here we present the OpenFlexure Microscope software stack as an example of how a scientific instrument can be controlled using existing, cross-platform, language-independent, industry-supported standards. We split the control code into client and server applications interfaced via a web API that conforms to the W3C Web of Things standard. This enables simple control of the microscope from multiple languages, provides a modern graphical control interface, and minimises duplicated code. Network control also makes the software stack more robust, allows multiple microscopes to be controlled by one computer, and facilitates sharing of equipment between local or remote users. Using a Web of Things approach in research laboratories has the potential to solve many of the key challenges of experiment integration, using technology that is already well established.
