Hello from Ultimate Robotics — who we are and why we're here

We're an open hardware team from Kyiv, Ukraine. We've been building open source hardware since 2012 — started with robotics, ended up making biosignal sensors because the tools we needed didn't exist at prices that made sense. That's how uE...

About

uDevices is the open hardware line from Ultimate Robotics — a small independent team based in Kyiv, Ukraine, building since 2012. 

We make uMyo, a wireless wearable EMG sensor, and uECG, a wearable ECG sensor. Both are fully open source — firmware, hardware, schematics. We sell assembled devices to fund continued development, but everything we build belongs to the community. 
Our work runs on UF1 — an open adapter protocol that lets any device plug into the same toolchain. The hardware is the product. The protocol is the infrastructure. 
We don't paywall tools or tier the community. If you're a maker, researcher, student, or developer working with biosignals — this is built for you.
