Agility Robotics Digit 5: The First Humanoid Robot Designed to Work Beside Workers—No Cage Required

Forum topic · 小凯 · 2026-09-18

Summary

On September 15, Agility Robotics unveiled Digit 5, a fifth-generation humanoid robot measuring 1.81 meters tall and 129 kg, with a 2.2-meter vertical reach matching standard industrial shelving. Its headline feature is fence-free operation: instead of isolating the robot behind safety cages, Agility embeds safety into the robot itself via a three-layer 'cooperatively safe' architecture—AI perception with redundant sensors, graded motion responses (rerouting, stopping, dropping into a low-center-of-gravity seated shutdown), and an independent motion supervisor that can trigger emergency stops. Digit 5 replaces the iconic backward-bent bird-like legs with an upright human-like configuration driven by new cycloidal actuators, lifting its repeated lifting load to 22.7 kg (up 40%). A new battery system delivers a 10:1 work-to-charge ratio (90 minutes run, 9 minutes to charge), enabling over 83% uptime without manual battery swaps. The robot spans inbound unloading, kitting, machine tending, optical inspection, and palletizing, managed through Agility Arc software on NVIDIA's IGX Thor platform with the Halos safety framework. First deliveries to the EU and UK are planned for H1 2027, backed by over $300 million in multi-year orders and a ~$2.5 billion SPAC merger with Churchill Capital Corp. XI.

On September 15, US robotics company Agility Robotics released Digit 5, its fifth-generation humanoid robot. Standing 1.81 meters tall and weighing 129 kg, it can reach 2.2 meters vertically—exactly the height a standard-height worker can reach on a logistics shelf. Every dimension is matched to the human-built world: it walks the same aisles, pushes the same doors, and reaches the same shelves. But the real change is another one: it no longer needs a fence.

What the fence was actually guarding against

The industry's vague justification for roping off humanoids was always that robots move fast and carry force. Agility's CEO, in a Bloomberg interview, clarified the real issue: the fence protects workers from being crushed if the robot loses balance and falls. Speed and force concerns rank second.

That distinction changes the solution space. If the risk is "moves too fast," the fix is speed limits, force limits, and caged workspaces. If the risk is "might fall over," the fix must come from posture control, center-of-gravity management, and hardware redundancy. Agility says it spent two years on the latter, calling the result cooperatively safe: the robot can share aisles with people within industrial safety standards, though close physical contact is still restricted—safety boundaries remain.

Three layers of protection

1. Perception – proprietary algorithms plus redundant sensor arrays continuously track people in the work area. 2. Motion response – graded by distance: reroute when someone approaches, stop and yield, and when someone gets very close, drop into a low-center-of-gravity seated posture and cut motor power. The "sit down" motion doubles as a clear visual signal that the robot has shut down, supplemented by lights and sounds announcing intent. 3. Supervision – an independent motion supervisor, separate from the main control system, triggers an emergency stop the moment anyone crosses a preset boundary.

The system runs on NVIDIA's IGX Thor compute platform with the Halos robotics safety framework; Agility is the first partner for NVIDIA's Halos for Robotics. The previous Digit 4 was the first humanoid to pass an OSHA independent safety review assessed on a real production line, not a lab.

Legs: the biggest hardware change

Digit 5 swaps the series' signature backward-bent, bird-like legs for an upright, human-like configuration driven by new cycloidal actuators. Human one-person lifting standards are written around human joint mechanics—the closer the leg configuration, the more controllable the load and the more predictable the fall risk. Result: repeated lifting load of 22.7 kg, up 40% over Digit 4, which Agility says covers most single-person lifts under OSHA rules.

| Dimension | Digit 4 | Digit 5 | Change | |---|---|---|---| | Max repeated lift | ~16 kg | 22.7 kg | +40% | | Height | ~1.68 m | 1.81 m | Human-matched | | Vertical reach | ~1.68 m | 2.2 m | Standard shelving | | Leg configuration | Backward-bent | Upright | Cycloidal actuators | | Work:charge ratio | 2:1 | 10:1 | Multi-fold uptime gain | | Work area | Fenced | Fence-free | No plant retrofit | | End effector | — | ISO flange quick-change | Swappable tools |

9 minutes of charge for 90 minutes of work

Digit 5 runs 90 minutes on a 9-minute charge—a 10:1 work-to-charge ratio, versus 2:1 for Digit 4. That translates to over 20 hours of effective work in a 24-hour cycle (>83% availability) with autonomous docking—no manual battery swaps, no extra scheduling, spares inventory, or safety procedures. By contrast, Figure's Figure 03 relies on longer charging stops or manual battery packs.

From tote carrying to the full chain

Digit 5 targets continuous factory workflows: inbound unloading, precision kitting and part sequencing, machine tending, optical inspection, and outbound palletizing, interfacing with existing AGVs and conveyors. Fleet management and telemetry run on Agility Arc, connecting to WMS, WES, and MES systems. Telemetry is protected with mTLS/TLS 1.2+ under customer-controlled certificates; vision data is processed locally at the edge.

Standards still being written, product already shipping

The "cooperatively safe" claim has no finished standard to compare against yet. Agility is participating in two in-progress documents: ANSI/A3 TR R15.108 (technical report on dynamically stable industrial mobile robots) and ISO 25785-1, billed as the first global safety standard for humanoid systems. Products landing before standards means buyers must assess risk themselves—"we helped write the standard" eases minds but doesn't replace a third-party assessment.

Orders, production, and a listing path

Digit 4 has logged over 65,000 paid working hours at GXO, Amazon, Schaeffler, and Toyota Canada; one GXO warehouse near Atlanta moved ~100,000 totes with ~98% accuracy. As of May 2026, Agility holds over $300 million in multi-year orders. First Digit 5 deliveries are set for H1 2027 (EU/UK, CE-certified), with scaled commercial deployment by year-end. Production takes place at the ~6,500 m² RoboFab factory in Salem, Oregon, with planned capacity of up to 10,000 units/year. A SPAC merger with Churchill Capital Corp. XI values the company at roughly $2.5 billion.

What to watch

Real incident records from fence-free deployments
Whether the 50-lb load is a peak or sustained rating—repeat count and duration aren't public
Whether the 10:1 charge ratio holds on real production lines
Timing of ISO 25785-1 finalization
Head-to-head comparisons with Figure, Atlas, and Apollo

Humanoid robots entering factories have long oscillated between maximizing generality and making one thing reliably deliverable. Digit 5 chose the latter, betting its safety architecture on removing the fence—the hardest line item in every factory retrofit budget. With that barrier gone, the question becomes: how far will a factory let a 129-kg object with a shifting center of gravity walk through its own aisles?
