Founder of Athena Labs. Physical AI that doesn't start at $15,000: robot arms and rugged edge AI computers for schools, labs and industry, designed and built in Almaty.

Building Tetsu. Describe it, build it: from one sentence to real CAD, wiring and firmware for robots and hardware.

First exit at 15 ($50k). Math olympiad. Into AI, robotics, physical AI, startups and venture.

Research

SUSS: What a Transformer Learns When It Adapts to Unknown Physics In-Context. A pre-registered mechanistic study. Small transformers are Bayes-optimal while data are scarce, the mechanism I pre-registered (an estimate in the residual stream) is not there, and the sufficient statistics turn out to live in the attention key-value memory: swapping only those keys and values between episodes moves 91-94% of the behaviour, and a second pre-registration confirmed it on three other architectures (11 of 11 tests). Also MuJoCo contact physics and an in-context controller that learns to explore. Paper · Project page · DOI 10.5281/zenodo.24031898

LISTEN: When Do Robot Policies Learn to Listen? A controlled, pre-registered study of why language-conditioned robot policies ignore their instructions. Holding the data budget, expert and architecture fixed and raising only the share of scenes demonstrated with several instructions from 0 to 0.5 lifts counterfactual instruction following from 48.9% to 71.3%.

Robot learning from scratch

No RL libraries, no IK packages, no OpenCV, no pretrained models: the interesting parts are written by hand, then measured.

ZOOMIES: the quadruped walking on velocity commands YOINK: the arm finding cubes with its camera and sorting them by colour COPYCAT: a learned policy placing a cube on a pad ARMageddon: the arm tracking a figure-eight with inverse kinematics

Project What it is Headline
ARMageddon inverse kinematics for a 6-DoF arm in pure NumPy 99.6% of 500 random 6D poses, about 0.7 ms per solve
YOINK vision-based pick-and-place: RGB-D cube detection, friction grasping 810 of 810 cubes sorted, every one on the first grab
COPYCAT imitation learning: scripted expert, DART noise, BC vs action chunking with 200 demos: ACT-lite 98%, chunked MLP 100%, plain BC 82%
ZOOMIES a quadruped I designed plus PPO written from scratch, 1024 robots in parallel walks in about 20 minutes, survives a 1.5 m/s kick 93% of the time
SPUD Isaac-lite for weak laptops: layer streaming and huge simulations a 2B-parameter model in 0.5-0.65 GB of VRAM; 65,536 robots walking at once

Out in the world

  • WetlandEar: open acoustic monitoring for nature reserves in Kazakhstan. The species classifier (wetlandear-ml) gets 74.2% per 3-second clip and 85.0% per recording across 268 species, against 56.3% for BirdNET on its own.
  • 365step: an EdTech app for SAT, IELTS, ENT and programming, with an AI tutor.

How I work

  • Hypotheses and tests go in a commit before the main experiments run. What failed stays in the paper.
  • Every number should be traceable to a results file the code wrote, not to my memory.
  • If it doesn't run on a 4 GB laptop, it doesn't ship. The laptop has opinions about this and falls asleep mid-run to share them.
