Documentation

MH-FLOCKE is a biologically grounded spiking neural network system for quadruped robot locomotion. No reinforcement learning, no gradient descent — the robot learns from embodied experience using the same principles biological nervous systems use.

The system runs on two platforms: a Unitree Go2 in MuJoCo simulation (1,376 neurons) and a Freenove Robot Dog on a Raspberry Pi 4 (560 neurons, real hardware, ~5 watts). Same architecture, same code, different bodies.

Key Results

Config Distance (m) Falls Variance
SNN + Cerebellum 45.15 ± 0.67 0 σ = 0.67
CPG only 40.73 ± 6.14 0.2 σ = 6.14
PPO Baseline 12.83 ± 7.78 0 σ = 7.78

3.5× further than PPO with 11.6× lower variance. 10-seed validation on Unitree Go2, 50k steps each. Zero falls across all seeds.

What Makes It Different

  • Spiking neurons — Izhikevich model with biologically realistic dynamics, not differentiable activations
  • Cerebellar forward model — Marr-Albus-Ito architecture with 4,000 granule cells for motor prediction and correction
  • Central Pattern Generator — innate locomotion rhythm that the SNN learns to modulate, not replace
  • Reward-modulated STDP — learning through spike timing and dopamine, not backpropagation
  • PID closed-loop steering — IMU-based drift compensation with asymmetric stride (v0.5.1)
  • Meta-learning loop — autonomous strategy adaptation through episode analysis, curiosity, and hypothesis testing (v0.5.1)
  • Runs on a Raspberry Pi — 38 steps/sec at ~5 watts, real-time on a 100€ robot kit
