SweepMe! – Flexible Lab Automation for Modern Research SweepMe! is a software platform that allows you to connect and automate measuring instruments from different manufacturers using a drag-and-drop interface. It empowers everyone in the lab to build test sequences – even without advanced programming skills. 🔁 Our open-source Python drivers and reusable modules simplify recurring test setups. Instead of reinventing the wheel, users benefit from a growing library of stable, proven components. This saves valuable time and enables faster validation of new test sequences. 📦 SweepMe! promotes sustainable workflows. Test procedures can be maintained and adapted even when staff changes, since the structure and modules are consistent and easy to understand – unlike custom-built, undocumented code. 🌍 Whether you’re at your home institute or working on-site at another lab: SweepMe! helps you get started quickly. Simply bring your sequence and run it on the local hardware. The shared logic and unified data format make collaboration and exchange with colleagues easier than ever. 📊 Built-in visualization, consistent file structure, and Python integration provide full flexibility and transparency – from quick experiments to long-term automation projects. Add complexity step by step, without needing to redesign your entire system. ⚙️ SweepMe! supports legacy hardware as well as modern instruments, making it ideal for upgrading old test setups or bridging the gap between generations of devices. ⏱️ Save time, reduce maintenance costs, and accelerate your test workflows – all with a low-cost solution and fast return on investment.

Controllab makes digital twins to test control software and build training simulators for the high-tech systems and marine & offshore markets. Our customers develop machines that use lot of control software. Testing this software is done when the machine is assembled on site. Problems in the control software can lead to delays and even damage. Our digital twins are simulation models that closely resemble a real machine. By coupling these twins to the control software, our customers can do tests without a real machine. They can solve problems easily and deliver software that works right the first time. With in-house developed simulation tools and over 30 years of experience, we can build digital twins that resemble real machines very accurately. We have special technology to make these twins run in real-time and show the machine in 3D animation. This makes our digital twins ideal for interfacing with control software. Our digital twins are so realistic, customers even use them for training. If you are developing machines, start using our digital twins and enjoy the benefits they bring: • Quality: On a digital twin you can test operations that are too expensive or too dangerous to do on a real machine. • Efficiency: On a digital twin you can instantly change anything. This means you can work much faster. • Costs: With a digital twin there are no operational costs of the real machine.
