Skill · Unitree G1

Two-arm choice

Two pathways, two arms: whichever pathway the neurons answer on, that arm rises.

01 Pathways

How the neurons drive it.

A pathway is one cue: the electrode we pulse, the electrodes we read, and the rule that decides when it is ON. This skill has two.

“right”

Pulse electrode
13at 10 Hz
Read electrodes
5 6 12 14 20 21 22
ON at
0.6spikes per electrode per 100 ms

We pulse electrode 13 at 10 Hz. When electrodes 5, 6, 12, 14, 20, 21 and 22 average at least 0.6 spikes per 100 ms, and twice the rate of the rest of the array, “right” is ON.

“left”

Pulse electrode
50at 10 Hz
Read electrodes
41 42 43 49 51 57 58 59
ON at
0.6spikes per electrode per 100 ms

We pulse electrode 50 at 10 Hz. When electrodes 41, 42, 43, 49, 51, 57, 58 and 59 average at least 0.6 spikes per 100 ms, and twice the rate of the rest of the array, “left” is ON.

These are the skill file’s starting electrodes, numbered column by column across the 8 × 8 array. Calibration moves each pathway onto electrodes your culture actually answers on and raises its ON threshold above resting noise.

03 The test

Moves only while cued.

Pulse ‘right’ 1–3 s, then ‘left’ 4–6 s: each arm rises only during its own window.

The test · 7 s · moves only while cued
right
right: pulsed 1–3 s

It passes when

  1. 01Right arm up in its window
  2. 02Left arm down in right window
  3. 03Left arm up in its window
  4. 04Right arm down in left window

04 Proof

Proof it is the neurons.

Validation replays this test three times on the same spontaneous activity. The skill counts only if it passes with stimulation and fails under both controls; if it also passes without the neurons, it is marked invalid.

With stimulationShould pass
No stimulationShould fail
Spikes blockedShould fail
