Ultimate Robotics
We build embodied, open hardware for human–machine interaction — serious tech, outside the startup machine.
2026

biosignal
a full open suite for working with EMG and IMU data (currently supports uMyos; other sensors welcome and planned) — written in MoonBit + Valence UI.

CV auto-labeling module

2021
uEMG bracelet
biosignal
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.
uPlant v1

plant monitoring that talks to you over a Telegram bot.
