Figure AI — Architecture Analysis
AI-FirstFigure AI is the highest-valued private humanoid company in the world ( $39B post-money, Series C, September 2025 [1]). Founded 2022 in Sunnyvale by Brett Adcock with a team drawn heavily from Boston Dynamics, Tesla, and Apple; ex-OpenAI engineers joined later via the now-ended OpenAI partnership. Where Tesla bets on vertical integration and Boston Dynamics on locomotion R&D, Figure bets on an in-house foundation model (Helix VLA) and an early commercial deployment at BMW Spartanburg.
AI-first, hardware-second: Figure's public technical output is dominated by Helix VLA papers and video demos, not actuator specs or supplier announcements. This page reflects that asymmetry: rich on the software story, deliberately honest about hardware blanks.
No public teardown: Unlike Tesla (where Morgan Stanley, China Merchants Securities, and patent filings provide a near-complete picture), Figure has no published BOM analysis, no patent portfolio of comparable depth, and no investor filings from Chinese tier-1 suppliers. Spec gaps below are flagged “Not publicly disclosed — pending teardown” rather than guessed.
Helix architecture:Per Figure's February 2025 whitepaper [2], Helix uses a System 1 / System 2 split: a fast (200 Hz) 80M-parameter visuomotor policy on-board, plus a slower (~7 Hz) 7B-parameter VLM that reasons over scene + language. This is the first publicly-announced VLA model with full upper-body continuous control. Trained on Figure's own teleop corpus after the OpenAI partnership ended.

Component-by-Component Teardown
Each Figure subsystem mapped to the closest commodity equivalent from our verified parts catalog. Where Figure has not disclosed a spec, the row is labelled Not Disclosed rather than filled in with speculation.
| Subsystem | Figure Implementation | Public Spec | Commodity Equivalent | Price | Gap |
|---|---|---|---|---|---|
| Hip / Shoulder Actuator | Figure proprietary rotary — believed to be brushless DC + harmonic reducer (not publicly confirmed) | Torque/RPM specs not publicly disclosed; Figure 02 demos suggest peak torque comparable to Optimus class (100–180 Nm range) | Harmonic FHA-25C (108 Nm) or EYOU PH20-101 (182 Nm) | $660–$2,400 | Not Disclosed |
| Knee / Leg Actuator | Figure proprietary — believed rotary (no linear-actuator patents on file matching Tesla's planetary roller screw approach) | Not publicly disclosed | T-Motor RMD-X8 (80 Nm) or CubeMars AK10-9 (50 Nm) | $420–$1,650 | Not Disclosed |
| Hand / Finger Actuation | Figure 03 hands — 16 DOF per hand (publicly stated in Oct 2025 reveal). Tendon-driven design publicly described. | 16 DOF/hand; tendon routing; tactile fingertip sensing claimed; per-finger DOF not broken down publicly | Dynamixel XL330 array (servo-per-DOF, 32 servos for both hands) | $65/servo (~$2,080 for 32) | Partial Gap |
| Compute | NVIDIA-based on-board compute (Figure has confirmed NVIDIA as a partner; specific module not publicly named) | Believed Jetson AGX Thor or Orin-class. Helix VLA inference runs on-board. Cloud offload for training only. | NVIDIA Jetson AGX Thor (2,070 FP4 TFLOPS, 130W) | $3,499 | Close Match |
| Battery | Third-party Li-ion pack (vendor not publicly disclosed) | Runtime ~5 hours stated for Figure 02; pack capacity, cell chemistry, and pack designer not in public record | Victron Lithium 48V 50Ah (2.4 kWh) | $3,200 | Not Disclosed |
| Vision | RGB cameras (count not publicly fixed; press images suggest stereo head + chest cameras) | 4K-class RGB; no LiDAR mentioned in any public reveal; Helix uses vision tokens directly into the VLM | Intel RealSense D455 + Logitech C920 | $400–$800 | Partial Gap |
| Tactile Skin | Fingertip tactile sensing on Figure 03 hands (claimed) | Cell count, modality (capacitive / resistive / barometric), and resolution not publicly disclosed | No drop-in commodity equivalent — research-grade only | Research only ($2K+ per finger) | Not Disclosed |
| Frame / Structure | Figure-designed structural frame; materials not broken out publicly | Figure 02: 60 kg, 165 cm. Figure 03 weight unchanged. Photographs suggest aluminum + composite, no carbon-fiber claims. | Carbon fiber mid-tier or aluminum frame | $3,500–$22,000 | Partial Gap |
Hip / Shoulder Actuator
Not DisclosedFigure does not publish actuator specs, supplier names, or torque tables. Press materials describe "electric actuators throughout" and "proprietary joint design." Architecturally Figure 02 appears closer to a conventional rotary stack than to Tesla's mixed rotary+linear approach. No teardown of a production Figure 02 exists in the public record. This is the largest spec gap in the entire stack.
Knee / Leg Actuator
Not DisclosedUnlike Tesla's well-documented planetary roller screw linear actuators (8,000 N), Figure has not published a knee architecture. Walking gait videos suggest a conventional rotary knee with reducer. If Figure uses harmonic drives at the knee, this is the most likely Suzhou Green Harmonic / Harmonic Drive Systems sourcing point — but Figure has named neither vendor.
Hand / Finger Actuation
Partial GapFigure 03 hands are tendon-driven, similar architectural class to Tesla Gen 3 (22 DOF) and Shadow Robot Hand. Figure claims 16 DOF/hand vs Tesla 22 — fewer total DOF, simpler routing. Actuator vendor for the tendon drives is not disclosed. Tactile sensing is claimed but resolution and cell count are not in the public record. This is the most-publicized component of Figure 03 but the spec sheet is still high-level.
Compute
Close MatchFigure has stated publicly that the robot runs an end-to-end vision-language-action model (Helix) on-board. The Helix whitepaper (Feb 2025) describes a System 1 / System 2 split: a fast 80M-parameter visuomotor policy plus a slower 7B-parameter VLM reasoner. This compute profile fits Jetson Thor. Figure has not confirmed the specific module. NVIDIA is a Series B investor, so Thor is the natural assumption.
Battery
Not DisclosedFigure has stated 5-hour runtime targets in press materials. No public confirmation of cell vendor, chemistry, pack architecture, or BMS design. Most likely sourced from a Korean or Chinese tier-1 (LG Energy, Samsung SDI, CATL, BYD) but no announcement on record. Pending teardown.
Vision
Partial GapFigure follows the vision-language-action paradigm pioneered by RT-2 / OpenVLA. Helix consumes camera frames directly into the VLM without an explicit depth/occupancy intermediate (per the Feb 2025 whitepaper). Camera count and sensor model are not on the public record. Architecturally this is closer to Tesla's vision-only doctrine than to Boston Dynamics' LiDAR-equipped Atlas.
Tactile Skin
Not DisclosedFigure has shown video of fingertip tactile feedback influencing grip force in Figure 03 demos. No technical paper has been published. Most likely candidates: Contactile (Australian capacitive arrays), GelSight (vision-based tactile, MIT spinout), or Figure's own development. Not publicly disclosed.
Frame / Structure
Partial GapNo Giga-Press analog. Figure manufactures at BotQ (Sunnyvale, CA) — a stated 12,000 units/year capacity facility. Frame is presumably machined and assembled rather than die-cast at Tesla's scale. Figure has not published a structural decomposition.

What Would It Cost to Build a Figure-Equivalent?
Running the closest commodity BOM through the HUMA Build Compiler — targeting 165 cm, 60 kg, 20 kg payload, 5 hr runtime, pro compute, 56 total DOF (24 body + 32 hand).
A commodity Figure-equivalent costs $38,565 vs Figure's current customer price of $150,000–$200,000 (target: $50,000 at volume). Commodity hardware now beats Figure's long-run target on price alone. The defensible moat is Helix, not the chassis.
Main-bus voltage mismatch: battery is 48V but 1 main-bus actuators expect different voltage
Dynamixel XM430-W350-T expects 12V
Power budget OK: 3553W effective peak vs 7200W battery
Actuator peak 11359W × 30% + 145W non-actuator
Multiple actuator protocols: EtherCAT, CAN, UART — requires a multi-protocol gateway
Compute (NVIDIA Jetson AGX Thor (T5000 Module)) bridges to actuator bus via motor controller
EtherCAT actuators detected with standard Linux compute. EtherCAT requires a real-time kernel (PREEMPT_RT patch). Stock Jetson Ubuntu will have jitter issues without RT patches. Consider: (a) apply PREEMPT_RT to Jetson, (b) use a dedicated EtherCAT master (Beckhoff), or (c) switch actuators to CAN protocol.
Missing hip or knee actuators
Mass budget OK: 39.2 kg / 60 kg (65%)
Compute too weak for pro tier: 0 TOPS < 200 TOPS required
Full VLA models (Helix, GR00T N1.5, π0.5)
Thermal budget tight: 802W simultaneous heat vs 30W passive (27× — active cooling required)
Harmonic Drive FHA-25C ×4: 324W each (η=73%); T-Motor RMD-X8 Gimbal Motor ×2: 302W each (η=82%); CubeMars AK10-9 QDD Actuator ×2: 230W each (η=80%); EYOU PH11-101 Harmonic Actuator ×2: 72W each (η=70%)

Runtime marginal: 3.4h estimated vs 5h target
Battery 2400 Wh ÷ avg 713W (actuators 568W at 5% duty + 145W always-on). Power management or reduced duty may be needed.

In-House vs Partner-Led
Where Tesla is vertically integrated by default, Figure's architecture is software-vertical, hardware-partnered: Figure owns the AI brain end-to-end and assembles the robot in-house at BotQ, but pulls compute from NVIDIA, cloud from Microsoft, and most component vendors remain undisclosed.

Funding & Captable
Figure has raised $2.5B+ cumulative across three rounds, reaching a $39B post-money valuation in September 2025 [1]. The captable concentrates strategic capital from chips (NVIDIA, Intel, Qualcomm), cloud (Microsoft), telecom (T-Mobile), software (Salesforce), consumer electronics (LG), and the commercial customer itself (BMW).
Why $39B matters: At this valuation Figure trades at roughly $260M of paper-equity per shipped robot (using the ~150 units/2024 figure). The company is priced on the bet that Helix becomes the operating system of every humanoid, not on the present hardware. This is the diametric opposite of Tesla's vertical-integration thesis — and explains why Figure's public technical output emphasizes AI papers over BOM teardowns.
Figure vs Tesla Optimus — Side by Side
The two companies sit on opposite axes of the same market. Tesla owns the hardware floor; Figure is racing to own the software ceiling.
| Dimension | Tesla Optimus | Figure 02 / 03 |
|---|---|---|
| Strategy | Vertical integration: design + build + train + deploy | Partnership-led hardware, in-house AI |
| Hand DOF | 22/hand (Gen 3, tendon-driven, 23 forearm linears) | 16/hand (Figure 03, tendon-driven) |
| Locomotion actuators | Mixed rotary + linear (planetary roller screw, 8,000 N) | Believed all-rotary; specs not disclosed |
| Compute | Custom AI4 / AI5 chip (Tesla-designed, Samsung/TSMC fab) | NVIDIA Jetson Thor-class (commodity) |
| Foundation model | End-to-end NN, 48 co-trained sub-networks, FSD-derived | Helix VLA (System 1 / System 2 split) |
| Training data moat | 8.2B vehicle miles + Cortex (~67K H100s) | Teleop corpus (size undisclosed) + Microsoft Azure compute |
| Manufacturing | Giga Press, Fremont line (Model S/X conversion) | BotQ Sunnyvale, 12K units/yr stated capacity |
| First customer | Internal (Tesla factories) — external pilots 2026 | BMW Spartanburg (live, Jan 2024 onward) |
| Valuation signal | Part of $800B+ Tesla parent | $39B private, AI-style multiple |
| Long-run unit price | <$20K target | $50K target (current $150–200K) |
Where Tesla is ahead
- •Hardware vertical integration (no commodity dependency)
- •Hand DOF (22 vs 16) and forearm linear-actuator architecture
- •Pre-existing FSD vision moat (8.2B miles transferred to robot)
- •Manufacturing scale (Giga Press, Fremont conversion)
- •Long-run unit cost target (<$20K vs $50K)
- •Custom silicon (AI5 vs commodity Jetson)
Where Figure is ahead
- •External commercial deployment (BMW live; Tesla still internal)
- •First publicly-announced VLA with full upper-body continuous control
- •AI talent density from OpenAI / DeepMind alumni network
- •Investor diversity (BMW, NVIDIA, Microsoft, OpenAI, LG, Salesforce)
- •Software releases cadence (Helix paper, video demos every quarter)
- •Lower hardware lock-in — easier to swap commodity components
Open Questions for the Portal
Items where Figure has not made the public record. We surface these here so visitors know what we know we don't know — and so the community can fill in gaps as teardowns appear.
Who supplies the rotary actuators?
Figure has not named a harmonic-drive partner, motor vendor, or contract assembler for joints. Candidates by elimination: Harmonic Drive Systems (Japan), Suzhou Green Harmonic (China — also Tesla supplier), Sumitomo, or fully Figure-internal. Pending teardown.
What battery cells and pack designer?
Pack supplier and cell chemistry not on record. Likely candidates: LG Energy (Series C strategic), Samsung SDI, CATL, BYD, or Northvolt. 5 hr runtime at humanoid power profile (~500 W mixed) implies ~2.5–3 kWh — consistent with a 48–52 V Li-ion pack.
Which Jetson module powers Helix on-board?
Figure has confirmed NVIDIA compute but not the SKU. Helix System 1 + System 2 split (80M policy + 7B VLM) fits Jetson AGX Thor. Could also be a multi-Orin configuration. Has implications for power budget and thermal headroom.
Tactile sensor cell count and modality?
Figure 03 fingertips show tactile feedback in demos but no spec sheet exists. Candidates: Contactile capacitive arrays, GelSight vision-based, custom barometric. Tactile resolution drives manipulation envelope.
Helix training corpus size?
Number of teleop demonstrations, hours of robot operation, and synthetic augmentation factor are all undisclosed. Tesla publishes 10,000× synthetic-per-real; Figure has published nothing comparable.
Contract manufacturer for high-volume scale-up?
BotQ stated capacity is 12K/yr. Beyond that, Figure has not announced a Foxconn / BYD / Flex-class CM. Required for the 100K+ unit ambition implied by the $39B valuation.
OpenAI partnership reversion terms?
Partnership ended early 2025 but the IP, training-data, and equity arrangement at termination is not public. OpenAI Startup Fund retains a Series B stake. Helix is described as Figure-built.
Figure 03 weight, exact DOF count, peak torque?
Figure 03 reveal (Oct 2025) showed redesigned hands (16 DOF) but did not republish a full body spec table. Whether Figure 03 changes body DOF from Figure 02's 24 is unclear.
Why This Matters for Kit Builders
A $39B valuation on ~150 shipped robots tells you the market is priced on which company owns the foundation model, not which ships the most chassis. Kit-builders should treat Helix-class VLA models as the core deliverable and the hardware as commodity packaging.
Figure on a BMW Spartanburg line is a public, ongoing existence proof that humanoids can do useful, repetitive work in a structured factory. That validates the whole category — and gives kit-builders a benchmark for what “good enough” means in the first commercial niche.
Figure's hardware is far more commodity-replicable than Tesla's. NVIDIA Jetson, off-the-shelf rotary actuators, third-party Li-ion: every layer except the brain is substitutable. Open-stack kits compete more directly with Figure 02 than with Optimus Gen 3.
