Digit 5: the Cage-Free Humanoid and Home Robot Safety

Why should home robot buyers care about a warehouse robot? Because industrial safety is the home-readiness filter. Every humanoid that may one day enter your living room must first prove it can share space with unpredictable humans without hurting them. Digit 5 is the first humanoid to make that case with deployment evidence rather than demo videos.

What Digit 5 actually is

Digit 5 is a 5 ft 11 in (1.81 m), 284 lb (129 kg) bipedal humanoid built for logistics and warehouse work. It handles single-person lift loads up to 50 lb (22.7 kg), navigates stairs, and coordinates in fleets via Agility Arc. It is sold as enterprise deployment and Robots-as-a-Service (RaaS — robots leased with maintenance and fleet software as a subscription), with no consumer pricing. (For comparison, the earlier Digit 4 was listed at 175 cm, 65 kg, with payload up to 16 kg.) Commercial operators include Amazon, GXO, Schaeffler, Mercado Libre, and Toyota Motor Manufacturing Canada. Production runs out of Agility's RoboFab facility in Salem, Oregon.

Digit 5 builds on three years of Digit 4 production-floor experience. According to Agility, customers representing more than $300 million in multi-year orders (subject to contractual milestones) shaped the requirements. Early access is expected in the first half of 2027, with general availability for manufacturing, warehouse, and distribution operators by the end of 2027. Agility also plans its first commercial deployment outside North America, starting with the EU and UK with CE marking.

The business context matters: Agility generated $1.8 million in net sales in 2025, plans to go public via a SPAC merger with Churchill Capital Corp XI valuing the company at $2.5 billion, and now needs Digit 5 to convert pilots into scaled deployments. Safety certification is the bottleneck it is trying to remove.

What changed in Digit 5

Four upgrades matter for anyone tracking home humanoids.

1. Cooperative safety architecture. Digit 5 continuously monitors for people using multiple sensor technologies and proprietary AI, then responds by avoiding the person, stopping, or sitting down. Visual and auditory cues signal motion intent so nearby people can participate in safe operation. An independent safety controller supervises the response whenever someone enters an unsafe distance and triggers the appropriate reaction instantly.

2. Independent safety validation. Agility says Digit previously became the first humanoid to pass an independent field evaluation on a customer production line for industrial safety standards administered by OSHA. Digit 5 extends that architecture rather than starting over.

3. Standards leadership. Agility says it is a project leader and contributor to ANSI/A3 TR R15.108, the technical report under development for dynamically stable industrial mobile robots including humanoids in the US and Canada, and to ISO 25785-1, described as the first international safety standard for the humanoid category. Whoever writes the safety standard shapes every home robot that follows.

4. Hardware built for repetition. New legs with proprietary cycloidal actuators — compact, high-torque rotary drives designed for shock loads — deliver a reported 40% more payload capacity and are engineered for repetitive lifting. Battery operations improved substantially: Digit 5 runs about 90 minutes and fully charges in about 9 minutes, a 10:1 run-to-charge ratio versus roughly 2:1 on Digit 4. That enables more than 20 hours of operation per day with fast autonomous charging. Digit 5 also adds manipulation skills beyond tote handling — depalletizing, machine tending, kitting and sequencing, and quality workflows — covering more of a facility's full workflow.

The compute partnership: NVIDIA Halos and IGX Thor

Agility says it is the first launch partner for NVIDIA's Halos for Robotics safety platform, pairing its systems with NVIDIA IGX Thor compute and Halos Core infrastructure. NVIDIA's robotics chief framed it plainly: safely operating around people and assets is what moves humanoids from pilots to industrial deployments at scale.

For home buyers, the takeaway is architectural. Safety cannot be a software patch on top of a fast, heavy biped. It has to span sensors, compute redundancy, an independent safety controller, and human-readable intent signaling. Expect the same stack — redundant sensing, a supervisor that can overrule the main planner, and explicit communication of intent — in any home humanoid worth trusting.

Why does removing the safety cage matter for home robots?

Traditional industrial robots work inside fences because they are fast, strong, and blind to context. Removing the fence means the robot must handle the hardest part of home robotics: unpredictable humans. Children run into the robot's path. Pets dart underfoot. Older adults move slowly and need extra reaction margin.

Digit 5's answer — detect, avoid, stop, or sit, plus signal intent — maps directly onto a home safety checklist:

• Does the robot detect people in all directions, including children and pets at low height?
• Does it default to a safe state (stop or sit) when uncertain, rather than pushing through?
• Can bystanders understand what it will do next from lights, sounds, or posture?
• Is there an independent safety supervisor separate from the main AI planner?
• Has any third party evaluated it against a published standard, not just the manufacturer's own test?

No home humanoid on the market today clears all five. That is exactly why Digit 5 matters: it shows what clearing them looks like in an industrial setting first.

What this means for home timelines

Be direct: Digit 5 is not a home robot. It is an enterprise RaaS platform with no public pricing, no home skills, and availability targeted at warehouses through 2027. Do not read this as a home launch.

What it does change is the timeline logic. Home humanoids from companies like 1X NEO, Figure 03, and Unitree G1 face the same trust problem Agility just spent three years solving: certifications (FCC, UL, ISO, CE), charger logistics, aisle and doorway clearances, workflow design, and documented safety behavior around people. Agility co-founder Jonathan Hurst put it well — doing the task was never enough (full story in From Digit 4 to Digit 5 below).

Any home humanoid company that cannot show equivalent homework — third-party evaluation, standards participation, fleet hours, and a documented safe-state behavior — is selling a demo, not a product. Ask for those four things before any preorder.

From Digit 4 to Digit 5: what three years on warehouse floors taught Agility

Digit 5 was not designed in a lab. Agility says its requirements came directly from customers after three years of Digit 4 working on production floors, and the design process was a first for the company: instead of building what engineers imagined as a technology demonstration, the team converted real deployment constraints into hundreds of engineering requirements.

Co-founder and chief robot officer Jonathan Hurst described the turning point during early work with Amazon. The robot did the job — moving bins off the putwall — but scaling up meant confronting FCC requirements, UL certifications, ISO certifications, and facility logistics nobody demos on stage: how wide are the aisles, where can chargers be bolted down, what does the workflow actually look like shift after shift.

That lesson generalizes. Every home humanoid startup currently showing polished demos will face the same wall the moment it tries to ship: certification regimes, charger placement (in your hallway, not a warehouse), doorway and furniture clearances, and hundreds of requirements discoverable only inside real homes. Companies with fleet hours learn this. Companies with only videos do not.

How Digit 5 compares to the home humanoid contenders

Nobody should cross-shop an enterprise RaaS biped against a consumer preorder. But the comparison is useful as a readiness audit — it shows which home contenders have deployment proof and which have promises.

The pattern: price and availability tell you what you can buy; safety evidence tells you what you should trust. Digit 5 leads on the second column by a wide margin, and it is not even trying to enter homes yet. Apply appropriate skepticism to any home humanoid that claims to be ahead of it on trust with a fraction of the proof.

The ui44 verdict: trust the safety evidence

Digit 5 does not put a humanoid in your home. It puts a filter on every company that promises to. The next time a viral video shows a humanoid folding laundry beside a child, ask the Digit 5 questions: who evaluated its safety, what standard did they use, what does it do when uncertain, and how many hours has it worked beside real people? Until those answers exist, keep your wallet closed and keep watching the warehouses — that is where home readiness is being earned.

That is the Digit 5 lesson for home buyers: trust the safety evidence, not the sizzle reel.
