Agility Robotics Digit — Architecture Analysis

Commercial-Live

Agility Robotics shipped the first commercial humanoid deployment in history at GXO Logistics in June 2024 [1]. A 2015 spin-out from the Oregon State University Dynamic Robotics Lab, Agility brings a decade of biomimetic locomotion research (ATRIAS, Cassie) into a warehouse-focused humanoid product. Where Tesla bets on vertical integration and Figure on an in-house foundation model, Agility bets on the deepest non-Boston-Dynamics locomotion R&D lineage and a commercial-first business model (Robots-as-a-Service).

Commercial milestone: June 2024 GXO Logistics deployment is the first humanoid in history to do real, billed, multi-shift warehouse work for a paying customer [1]. Tesla, Figure, Apptronik, and Boston Dynamics all remain in pilot or internal-deployment stages as of writing. Agility's lead here is measured in production hours, not just press releases.

No public teardown: Agility publishes deployment milestones and high-level specs but does NOT publish actuator model numbers, peak torque tables, battery cell vendors, or contract-manufacturing partners. Cassie heritage is well-documented in OSU academic papers; the productised Digit stack is far less public. Spec gaps below are flagged “Not publicly disclosed” rather than guessed.

Backwards-knee design:Digit's most visible mechanical signature is its reverse-knee bipedal leg — biomimetic ostrich/emu kinematics inherited from OSU ATRIAS (2013) and Cassie (2017) [2]. The knee bends backwards relative to human anatomy, optimising walking energy economy. This is a deliberate departure from human-anatomical bipeds (Optimus, Figure, Atlas, Apollo). It divides opinion — some argue it's not a humanoid; Agility argues function beats form.

Component-by-Component Teardown

Each Digit subsystem mapped to the closest commodity equivalent from our verified parts catalog. Where Agility has not disclosed a spec, the row is labelled Not Disclosed.

Hip / Shoulder Actuator

Not Disclosed
Digit
Agility-designed series-elastic actuator (SEA), derived from OSU Cassie heritage; specific model numbers not disclosed
Cassie-class SEA: brushless DC + planetary reducer + leaf-spring elastic element + torque sensor. Per-joint torque/RPM tables not published.

Digit's actuator family descends directly from the OSU Cassie research robot (2017) — series-elastic, brushless DC, planetary-stage reduction. Compliance is intrinsic to the design (the elastic element absorbs impact and stores energy during walking). Agility has NOT published model numbers, peak torque per joint, or supplier names. Closest commodity proxies: harmonic-drive rotaries for stiffness, T-Motor / CubeMars quasi-direct-drive for compliance. Neither is a true SEA — the spring element is what makes Cassie/Digit walking efficient.

Knee — Backwards-Knee Geometry

Different Approach
Digit
Reverse-knee bipedal leg, biomimetic ostrich/emu-inspired kinematics (Cassie heritage)
Knee bends backwards relative to human anatomy — heel-equivalent is the ankle joint, ankle-equivalent is the toe. Optimised for dynamic walking efficiency.

The backwards-knee design is Digit's most visible architectural signature — and a deliberate departure from human-anatomical bipeds (Optimus, Figure, Atlas, Apollo). Roots: Jonathan Hurst's research at Oregon State Dynamic Robotics Lab, where ATRIAS (2013) and Cassie (2017) used point-feet ostrich-style legs to maximise walking energy economy. Digit retains the leg topology but adds a torso, arms, and end-effectors. Commodity rotary actuators can replicate the joint torques; the kinematic chain is the differentiator and is well-documented in OSU papers.

End Effector / Hand

Not Disclosed
Digit
End-effector hardware has evolved: early Digit used 4-finger paddle grippers; current production units have transitioned to articulated hands. Specific DOF count and design generation not consistently published.
Payload 16 kg per arm (published). Hand DOF: not publicly fixed at the time of writing. Tactile sensing: not publicly disclosed.

Agility's end-effector strategy is warehouse-driven: grasp totes, lift packages, place items on conveyors. This is a far simpler manipulation envelope than Optimus's 22-DOF tendon hands or Figure's 16-DOF tendon hands. Digit has historically prioritised payload (~16 kg) over manipulation dexterity. The exact current production hand spec (DOF count, tactile sensing, gripper-vs-hand) has not been consistently published and varies between generations.

Compute

Close Match
Digit
On-board compute — NVIDIA-class (graph.ts pairs agility with nvidia-thor). Specific module not publicly named.
Believed Jetson AGX Thor or Orin-class. Cassie's research stack used Intel NUC + ROS — Digit's production compute is presumed upgraded but not detailed in public materials.

Knowledge-graph wiring (graph.ts: agility → nvidia-thor) places Digit on the same NVIDIA-class compute stack as Figure, Apptronik, UBTech. NVIDIA is a confirmed industry partner across the warehouse-humanoid cohort. Agility has not confirmed the SKU. Locomotion stack (the harder problem) is well-understood from OSU Cassie publications; perception + foundation-model strategy is less public.

Battery

Not Disclosed
Digit
Third-party Li-ion pack — vendor not publicly disclosed
Runtime 4+ hours (companies.ts spec). Pack architecture, cell chemistry, BMS designer not in the public record.

Agility states 4+ hour runtime per charge with hot-swappable battery packs (key for warehouse multi-shift operation). Cell vendor not announced — likely candidates: LG Energy, Samsung SDI, CATL, BYD, or a US-domiciled supplier given Albany OR / Salem OR manufacturing footprint. Hot-swap pack architecture is publicly demonstrated in GXO deployment videos.

Vision — Stereo + LiDAR

Partial Gap
Digit
Stereo cameras + LiDAR (Intel RealSense reported in earlier prototypes; LiDAR class not specified)
Perception stack designed around perceptive step planning — a Cassie heritage. Sees terrain, plans footfall, balances dynamically.
Commodity
Intel RealSense D455 + LiDAR (Slamtec RPLIDAR S2)
$400–$800 + ~$650 LiDAR

Unlike Tesla's vision-only doctrine and Figure's RGB-first VLA approach, Digit retains LiDAR — consistent with its locomotion-first heritage. OSU Cassie used Intel RealSense for terrain perception in published research. Production Digit configuration not exhaustively documented but stereo + LiDAR is consistent across press materials and demo videos.

Force/Torque Sensing

Close Match
Digit
Force/torque sensors at wrists and feet (graph.ts: agility → force-torque)
6-axis F/T at end-effectors and contact points. Critical for tote handling and dynamic walking foot-placement.

Force/torque sensing is explicit in graph.ts wiring (agility → force-torque) and a known requirement for warehouse manipulation tasks. ATI Industrial is the dominant Western F/T sensor supplier — likely though not confirmed source. Cassie's research stack used custom load cells; Digit's production sensors are presumably commercial.

Frame / Structure

Partial Gap
Digit
Aluminum + composite structural frame. Manufacturing at RoboFab (Salem, OR), 70,000 sq ft facility, stated 10,000 units/year capacity.
65 kg total mass, 175 cm tall. No Giga-Press analog. Final assembly in-house at Salem.

RoboFab opened September 2023 as the first dedicated humanoid robot factory in the US. Stated 10K/yr capacity. Frame is machined and assembled rather than die-cast at Tesla's Giga-Press scale. Materials decomposition not publicly broken out. Mass budget (65 kg at 175 cm) is heavier than Figure (60 kg at 165 cm) and Optimus (57 kg at 173 cm) — reflecting payload-optimised design.

What Would It Cost to Build a Digit-Equivalent?

Running the closest commodity BOM through the HUMA Build Compiler — targeting 175 cm, 65 kg, 16 kg payload, 4 hr runtime, pro compute, 19 body DOF (Digit publishes a low-DOF spec compared to Optimus 28 or Atlas 56).

A commodity Digit-equivalent costs $41,695 vs Digit's ~$175,000 sticker price (companies.ts:agility-digit.spec.price). Note: Agility primarily sells access to Digit via RaaS rather than units — list price is a reference, not the primary go-to-market. Commodity hardware now beats Digit on price alone. Agility's defensible asset is the locomotion stack and the GXO production-hours moat, not the BOM.

In-House vs Partner-Led

Agility's vertical is locomotion + manufacturing: the company owns the Cassie-heritage actuator design + walking controllers and assembles units in-house at RoboFab Salem. It partners on compute (NVIDIA-class), batteries (third-party Li-ion), and customer integration (GXO, Amazon).

Agility Owns / Makes In-House

Series-elastic actuator design (Cassie heritage)
Agility's actuator IP descends from a decade of Oregon State Dynamic Robotics Lab research. Founders Jonathan Hurst, Damion Shelton, Mikhail Jones brought the SEA + biomimetic-leg approach into the company at 2015 spin-out. Manufacturing is in-house at RoboFab Salem; specific motor + reducer suppliers not disclosed.
Backwards-knee bipedal kinematics
The defining mechanical signature. Roots in OSU ATRIAS (2013) and Cassie (2017) point-feet ostrich-style legs. Digit added torso + arms while preserving the energy-efficient leg topology. Documented in published OSU papers; geometry is public, control software is proprietary.
Walking + balance control stack (Cassie research lineage)
Agility's locomotion controllers descend from OSU Cassie research that demonstrated 5K runs, stair climbing, and field-deployable walking. This is one of the deepest locomotion R&D lineages outside Boston Dynamics.
RoboFab manufacturing facility (Salem, OR)
70,000 sq ft, opened September 2023, stated 10,000 units/year capacity. First dedicated humanoid robot factory in the US. Final assembly is Agility-internal — no contract manufacturer disclosed.
Robots-as-a-Service (RaaS) commercial model
Agility pioneered the RaaS pricing structure for humanoids — customers pay per hour of robot operation rather than capex purchase. Active at GXO Logistics. Sets the pricing template the rest of the industry now references.

Partners / Confirmed Relationships

GXO Logistics — first commercial customer
Agility announced the first commercial humanoid deployment in history at GXO Logistics in June 2024 (per companies.ts:agility-digit.keyPartners and Agility press release dated June 2024). Site: Spanx warehouse, GXO-operated. Tasks: tote handling, package movement. RaaS billing — Agility owns the robots, GXO pays per shift. Multi-shift continuous operation is the publicly-stated milestone. This is the single most important deployment in the commercial humanoid market to date.
Amazon Industrial Innovation Fund — strategic investor + pilot customer
Amazon IIF participated in Agility's 2024 Series D extension (companies.ts:agility-digit.funding[4]). Digit is in pilot at Amazon's Seattle R&D facility on tote recycling and material handling. Amazon is both an investor (~$150M+ extension round) and a deployment partner — the same playbook Amazon has run with Covariant, Rivian, and other strategic robotics bets.
DCVC + Playground Global — long-running financial leads
DCVC has led Agility's Series A (2018), Series B (2020), and Series C (2022 — $150M). Playground Global co-led Series B. This is one of the most consistent VC syndicates in humanoid robotics. DCVC's deep-tech thesis predates the post-ChatGPT humanoid wave.
Oregon State University — research lineage + talent pipeline
Agility was a 2015 spin-out from the OSU Dynamic Robotics Lab. Founders Jonathan Hurst, Damion Shelton, Mikhail Jones; OSU continues to produce graduate-level locomotion research that feeds Agility hiring. Cassie remains the open research platform; Digit is the productised descendant.
NVIDIA — compute partner
graph.ts:agility → nvidia-thor links Digit to the industry-standard NVIDIA Thor / Jetson compute stack. Specific module not publicly confirmed by Agility but consistent with industry-wide convergence on Jetson-class on-board compute.
Apptronik — adjacent peer (graph.ts adjacency)
graph.ts wires agility → apptronik as adjacent USA-based humanoid players. Both target warehouse / logistics and use SEA-class actuators. Not a confirmed commercial partnership but a structural peer relationship in the US humanoid landscape.

Funding & Captable

Agility has raised $500M+ cumulative across five rounds, reaching an estimated ~$1.4B valuation (companies.ts:agility-digit). The captable pairs deep-tech VCs (DCVC consistent across A/B/C, Playground Global on B) with a single anchor strategic at extension stage (Amazon Industrial Innovation Fund) [3].

Why ~$1.4B matters: Compared to Figure's $39B, Agility trades at roughly 3.5% of Figure's paper-equity— yet it has already shipped the first commercial humanoid deployment in history. The market is pricing Figure on a foundation-model bet and Agility on a steady commercial-revenue trajectory. If Helix-class VLA capability becomes generic, Agility's GXO moat (production hours, customer trust, RaaS billing infrastructure) compounds — and the valuation gap narrows.

Customer Story — GXO Logistics (Spanx, June 2024)

The single most important deployment in commercial humanoid history. Agility and GXO Logistics announced multi-year RaaS agreement in June 2024, deploying Digit at a Spanx-fulfilment warehouse operated by GXO [1].

Deployment Profile

  • Site: GXO-operated Spanx fulfilment warehouse, USA
  • Tasks: Tote handling, package movement, conveyor-line transfer
  • Shift profile: Multi-shift continuous operation (~7 hour shifts publicly cited; hot-swap battery between shifts)
  • Billing: RaaS — GXO pays per hour of robot operation, Agility owns the hardware
  • Announced: June 2024 (Agility + GXO joint press release)

Why It's a Milestone

  • First, period: The first humanoid in history doing real billed warehouse work for a paying enterprise customer
  • Validated RaaS: Agility's pricing model has now been proven at a tier-1 3PL — the rest of the cohort is pricing-following
  • Behavioural envelope: Demonstrates that 19 DOF + 16 kg payload is enoughfor a real economic task. You don't need 28 DOF or 22-DOF hands to extract real warehouse value.
  • Defensible moat: Every hour Digit operates at GXO is data + customer-trust no competitor has. Tesla, Figure, Apptronik are still in pilot.

The implication for kit builders:Digit's GXO win proves the warehouse market doesn't need a 22-DOF tendon-driven hand to monetise. A 19-DOF biped with a simple gripper and 16 kg payload is enough. That is a much lower hardware bar than building an Optimus or Figure clone — and the manipulation gap can be closed incrementally with software.

Digit vs Optimus vs Figure — Side by Side

Three philosophies from the same year. Tesla owns the hardware floor; Figure owns the AI ceiling; Agility owns the customer-base.

Where Digit is ahead

  • First commercial humanoid deployment in history (GXO, Jun 2024)
  • Deepest non-Boston-Dynamics locomotion R&D lineage (OSU, decade-plus)
  • Validated RaaS pricing model — the rest of the cohort is following
  • Production hours moat at GXO — months of real billed work
  • Backwards-knee design: walking energy efficiency advantage
  • Lower DOF target = lower BOM cost at equivalent payload

Where Optimus / Figure are ahead

  • Higher hand DOF (22 / 16 vs Digit's low-DOF gripper)
  • More mature foundation-model story (Helix VLA, end-to-end FSD-derived NN)
  • Higher unit-economics ceiling at scale (target $20K / $50K vs Digit ~$175K sticker)
  • Larger raise + valuation = longer runway for hardware iteration
  • Human-anatomical form factor reads more naturally to general-public market
  • Tesla's Giga-Press manufacturing scale advantage at 100K+ unit volume

Open Questions for the Portal

Items where Agility has not made the public record. Surface these here so visitors know what we know we don't know — and so the community can fill in gaps as teardowns and academic publications appear.

Q1.

What are the actuator model numbers and peak torque tables?

Agility's SEAs descend from OSU Cassie (well-documented in academic papers — Hurst, Fern, Hubicki et al.) but the productised Digit actuators have NOT had model numbers, peak torque per joint, or supplier names disclosed. This is the largest single spec gap. Cassie publications give a research-grade reference; production specs likely diverge.

Q2.

Who supplies the battery cells and pack architecture?

Cell vendor, chemistry, BMS designer not on record. Hot-swap pack architecture is publicly demonstrated. 4+ hour runtime at humanoid power profile (~400-500 W mixed) implies ~2-3 kWh per pack. Likely candidates: LG Energy, Samsung SDI, CATL, BYD, or a US-domiciled supplier given Salem OR manufacturing footprint.

Q3.

Who is the contract manufacturer for actuator components?

RoboFab does final assembly. Upstream — motor windings, harmonic / planetary reducers, encoder packs — Agility has not announced a CM partnership. Closest analogues: Tesla uses Sanhua + Tuopu + Green Harmonic; Figure uses undisclosed; Agility likely uses a mix of US + Asian suppliers given the US-flag investor base.

Q4.

What is Agility's foundation-model strategy?

Locomotion + balance is well-understood from Cassie heritage. Manipulation, language understanding, and end-to-end task learning are far less public. Agility has not announced an in-house VLA model (Helix-class) nor a foundation-model partnership (Physical Intelligence, NVIDIA GR00T, Google Gemini Robotics). This is the biggest strategic blank.

Q5.

What is the exact Digit V5 / V6 hand specification?

End-effector hardware has evolved across generations. Early Digit used 4-finger paddle grippers; current production has transitioned to articulated hands. Specific DOF count, tactile sensing modality, and design generation (V5 vs V6) are not consistently published. Material for a future teardown.

Q6.

What are the per-shift unit economics at GXO?

RaaS billing rate per hour, GXO contract length, and Agility's gross margin per Digit-shift have not been disclosed. These numbers will define whether RaaS is a sustainable model — and whether Tesla's direct-sale-at-$20K can undercut it on a per-task-cost basis.

Q7.

Compute SKU on-board?

graph.ts wires agility → nvidia-thor but Agility has not confirmed Thor specifically. Could be Jetson AGX Orin (current generation), Thor (next generation), or a multi-Orin configuration. Has implications for thermal envelope and on-board model size.

Q8.

How does Digit handle the Cassie point-foot to humanoid-foot transition?

Cassie used point-feet (no toe articulation). Digit added a foot for stability + payload but kept the backwards-knee leg topology. The exact ankle / foot mechanism has not been deeply documented in production materials. OSU papers cover the research lineage; Digit's production foot may have evolved further.

Why This Matters for Kit Builders

Lower DOF can be enough

Digit ships with 19 body DOF — 9 fewer than Optimus, 5 fewer than Figure — and is doing real billed work at GXO. The warehouse market does not require a 22-DOF tendon hand. Kit builders targeting logistics can ship with simpler grippers and still compete on the economic-task envelope.

Locomotion is the floor, not the ceiling

Cassie heritage gives Digit a decade-plus lead on walking efficiency. Open-source equivalents exist (MuJoCo Cassie models, Berkeley humanoid stack) but the production-grade tuning and field-deployment maturity are non-trivial. Walking well is harder than it looks; Cassie publications are the public on-ramp.

RaaS is the proven path to revenue

Selling robots is hard. Selling robot-hours is easier — the customer pays operating cost, you keep the asset. Agility proved this at GXO. Kit builders who sell as RaaS rather than $50K hardware boxes have a structurally easier go-to-market.
