Ultimate Robotics
We build embodied, open hardware for human–machine interaction — serious tech, outside the startup machine.
2026
a full open suite for working with EMG and IMU data (currently supports uMyos; other sensors welcome and planned) — written in MoonBit + Valence UI.

decoding
built from scratch at the July 2026 hackathon — a camera watches a session and labels the gestures, so the muscle-signal recognizer can learn from footage instead of scarce hand-labels.

the ecosystem around the sensor — a LiPo charger, a CR2032 holder.
new two-piece PCB, 3D-printed enclosure.

uMyo driving a game as a controller — muscles as input (a demo from this era).
2022
proof of concept, then the first uMyo available for sale.
modular IoT sensor system
sensing
composable ESP32 sensor nodes — CO₂, particulates, humidity, temperature, ambient light, relays — daisy-chainable, USB-A or USB-C. Built right before the full-scale invasion.
2021
a four-channel wearable EMG; several iterations of an e-textile bracelet.
gesture recognition (k-means)
decoding
cluster the muscle-signal features, name the clusters, and you have gestures — the recognition line, made public.
muscle ──► [ 200ms window ] ──► amplitude + band-energy ──► [ sorter ] ──► gesture
a few numbers k-means / NN
How the recognition works, briefly
Muscle signal → a few numbers per short window (amplitude and frequency-band energy) → sort those numbers into named piles. Every method is a different sorter — nearest-neighbour, k-means, and, under the products, a decade of hand-built ML (autoencoders, self-organizing maps, PCA). The camera-labeling work exists to feed that sorter the labels a person can't be bothered to write.
plant monitoring that talks to you over a Telegram bot.
musical instrument digitization
decoding
capturing how a stringed instrument is actually played — which strings, the process — from its sound.
wildlife telemetry
biosignal
a uECG firmware variant for a research lab studying animals; they published with it.
2020
an open patient monitor for nRF52-based devices — the many-sensor branch.
an open-source pulse oximeter.
HackCorona · #EUvsVirus
uECG, uOxy and uDoc taken to the pandemic hackathons — the open-patient-monitor moment, why uDoc and uOxy exist.

open wireless ECG wearable, on-board processing — a successful Indiegogo campaign, devices shipped.
individual-finger control from EMG (with uECG)
decoding
a robotic hand's fingers, one muscle signal each — the recognition high-water mark.

an AR module that clips onto your glasses.
EMG/EXG capacitive electrodes
biosignal
single-channel hex-shaped boards reading electrical activity.
the line drawn — no person-tracking
