# K-Scale Ecosystem Skill

> *"Moving humanity up the Kardashev scale"* — Ben Bolte, K-Scale Labs

## Trigger Conditions

- User asks about K-Scale Labs, their robots, or open-source robotics stack
- Questions spanning simulation → training → deployment pipeline
- Humanoid robot development workflows
- Integration of multiple K-Scale repositories

## Overview

**K-Scale Labs** is building open-source humanoid robots with a complete software stack:

## GF(3) Trit Assignment

```
Trit: 0 (ERGODIC)
Role: Coordination (ecosystem meta-skill)
Color: #86E3BE
URI: skill://kscale-ecosystem#86E3BE
```

### Balanced Triads

```
# Corrected trit assignments from share3_hash:
kscale-ecosystem (0) ⊗ kscale-ksim (0) ⊗ kscale-kos (-1) = -1 ≢ 0

# Balanced triad with gym:
kscale-ksim (0) ⊗ kscale-kos (-1) ⊗ gym (+1) = 0 ✓

# Balanced quad with skill-creator:
kscale-ecosystem (0) ⊗ kscale-ksim (0) ⊗ kscale-kos (-1) ⊗ skill-creator (+1) = 0 ✓
```

### Skill Trits

| Skill | Trit | Color | Role |
|-------|------|-------|------|
| `kscale-ecosystem` | 0 | `#86E3BE` | Coordination (meta-skill) |
| `kscale-ksim` | 0 | `#25BC3D` | Coordination (simulation) |
| `kscale-kos` | -1 | `#7758D6` | Validation (firmware) |
| `kscale-kinfer` | -1 | `#6E5FE4` | Validation (inference) |
| `gym` | +1 | (balancer) | Generation (RL environment) |

## Mutual Awareness Pattern

These skills form a **mutually-aware cluster**:

```yaml
# In kscale-ksim.md
related_skills:
  - kscale-kos      # deploys trained policies
  - kscale-kinfer   # exports models
  - kscale-ecosystem # meta-context

# In kscale-kos.md  
related_skills:
  - kscale-ksim     # receives policies from
  - kscale-kinfer   # uses for inference
  - kscale-ecosystem # meta-context

# In kscale-kinfer.md
related_skills:
  - kscale-ksim     # receives models from
  - kscale-kos      # runs on
  - kscale-ecosystem # meta-context
```

## Development Workflow

### 1. Model Preparation
```bash
# Convert URDF to MuJoCo format
urdf2mjcf robot.urdf --output robot.xml
```

### 2. Policy Training
```bash
# Train walking policy with ksim-gym
cd ksim-gym
python train.py --robot kbot --task walk --steps 80
# ~30 min on RTX 4090
```

### 3. Model Export
```bash
# Export to ONNX for deployment
python export.py --checkpoint model.ckpt --output policy.onnx
```

### 4. Deployment
```bash
# Deploy to K-Bot via KOS
kos deploy --model policy.onnx --robot 192.168.1.100
```

## Key Technologies

| Layer | Technology | Purpose |
|-------|------------|---------|
| Physics | MuJoCo/MJX | Accurate contact simulation |
| Compute | JAX | GPU-accelerated training |
| Learning | PPO | Policy optimization |
| Inference | ONNX Runtime | Cross-platform deployment |
| Firmware | Rust | Safe, real-time control |
| Protocol | gRPC | Robot communication |
