Actuation at roughly 40–60% of total humanoid hardware cost
After reviewing current teardown estimates, McKinsey supply-chain analysis, Interact Analysis actuator research, Morgan Stanley Optimus estimates, Nvidia humanoid ecosystem announcements and industry BOM studies, here the estimated humanoid value distribution today :
| System | Share of Hardware BOM |
| Actuators, motors, reducers, joint modules, hands | 45–60% |
| AI Compute & Control | 10–18% |
| Vision & Perception Sensors | 5–12% |
| Power Electronics & Battery Management | 8–15% |
| Networking, Connectivity & Safety Electronics | 3–8% |
| Magnets & Rare Earth Materials | 5–10% |
| Mechanical Structure, Bearings & Thermal | 10–20% |

Actuation remains by far the largest value pool. Multiple studies place joint actuators above 30% of BOM and often above 50% in simpler humanoids. McKinsey estimates actuation at roughly 40–60% of total humanoid hardware cost.
For Tesla Optimus specifically, industry estimates suggest actuators account for roughly 56% of hardware cost, with reducers alone around 15%.
Sources supporting the distribution include public McKinsey humanoid teardown analysis, Interact Analysis actuator cost studies, Morgan Stanley Optimus BOM estimates, Reuters reporting on Nvidia’s humanoid ecosystem and Schaeffler actuator supply chain expansion.

Key takeaway from these sources:
While AI compute receives most of the attention, current research consistently shows that actuators, motors, reducers and joint modules represent the largest value pool in humanoid robots—typically accounting for 45–60% of total hardware cost. The humanoid opportunity is therefore not only an AI story, but equally a motion-control, power-electronics and semiconductor story.
