What is a BOM?
A BOM (Bill of Materials) is the complete list of every component, material, and sub-assembly needed to build one unit of a product. For a robot, it’s the spreadsheet that separates a 150,000 prototype.
What’s in a Humanoid BOM
| Tier | Components | Typical Cost |
|---|---|---|
| Compute | GPU/AI accelerator, CPU, memory | 8,000 |
| Actuators | Motors, gearboxes, encoders (20–40 units) | 15,000 |
| Sensors | LiDAR, cameras, imu, tactile sensors | 3,000 |
| Battery | lfp-battery pack, BMS, charging circuitry | 3,000 |
| Frame / Structure | Aluminum, carbon fiber, plastics | 2,000 |
| Cables / Connectors | Wiring harnesses, power distribution | 800 |
| Software / Licensing | OS, middleware, AI model weights | 5,000 |
Total BOM for a humanoid in 2026: ~40,000 depending on specs and volume.
BOM vs. Retail Price
| Robot | Estimated BOM | Retail Price | Margin |
|---|---|---|---|
| Unitree G1 | ~12,000 | $13,500 | Thin — volume play |
| Figure 02 | ~35,000 | Not sold; raas model | N/A |
| boston-dynamics-atlas | Boston Dynamics Atlas]]|Boston Dynamics Atlas]] | ~$100,000+ | Not sold |
| Tesla Optimus (target) | ~20,000 | TBD | Vertical integration goal |
The Volume Effect
At 1,000 units/year, each actuator costs 150–$200. This is why Tesla’s 10M robot/year target matters — not just for revenue, but for BOM cost collapse.
The Bottom Line
The BOM is the economic reality of robotics. finance|Investors]] and major-players\ who understand BOMs know that the companies winning aren’t just those with the best AI — they’re the ones who can drive component costs down through volume, vertical integration, or Supply Chain control.
