While many companies chase the dream of a general-purpose AI humanoid robot, Agility Robotics took a different path. They asked a simpler, more pragmatic question: what specific job does a robot need to do today? The answer, for them, was logistics—the movement of goods in warehouses and distribution centers. This singular focus gave birth to Digit, a humanoid robot that prioritizes function over form, making it one of the most commercially advanced and deployed machines in the world.
From our firsthand experience operating various platforms, Digit's design philosophy is a breath of fresh air. It's not trying to win a beauty contest; it's built to move totes, clear obstructions, and work seamlessly alongside humans in environments designed for people. This article dives deep into what makes Digit unique, its technical capabilities, and why it's a frontrunner in the race to automate physical work.
The Agility Robotics Philosophy: Solving the Labor Gap
Origins at Oregon State University: From Cassie to Digit
Agility Robotics was co-founded by Dr. Jonathan Hurst and Dr. Damion Shelton, spinning out of Oregon State University where Hurst pioneered highly efficient legged locomotion with robots like Cassie. The company's mission has always been starkly practical: to solve real-world problems, starting with the massive and growing challenge of labor shortages in the logistics sector.
A "Logistics-First" Design Mindset
Unlike companies aiming for a grand AI robot butler, Agility focused on a viable customer and a clear use case from day one. This "logistics-first" mindset informs every aspect of Digit's design, making it less of a general humanoid and more of a "mobile manipulation" platform optimized for its intended task.
Design Philosophy in Action
While competitors focused on creating human-like appearance and movement, Agility Robotics asked: "What's the most efficient way to move a tote from point A to point B in a human-built environment?" This fundamental question led to Digit's unique biomechanical design that prioritizes function over form.
Design & Engineering: Form Radically Follows Function
Biomimetic "Bird-Leg" Locomotion
Digit's most striking feature is its legs, inherited from the Cassie robot. This biomechanical design is inspired by ostriches, creating a natural squatting posture that is exceptionally power-efficient for walking and balancing. This is a stark contrast to the straight-legged design of robots like the Unitree H1 or Tesla Optimus.
Lightweight and Resilient Construction
Digit is built from lightweight materials and features a compliant design. Instead of rigidly resisting every impact, its legs and arms can absorb and yield to force, making it safer around humans and more durable when (not if) it takes a tumble.
Integrated Perception: A Torso-Mounted "Head"
Digit's head contains cameras, but its primary perception suite (LIDAR and additional cameras) is housed in its torso. This provides a stable, central vantage point and protects sensitive sensors from damage.
Purpose-Built Arms for Manipulation and Stability
Digit's arms are simple, strong, and purposeful. They are designed to lift and carry totes (up to 35 lbs / 16 kg) and are capable of a "high reach" to access standard shelving. They can also use their arms for stability, bracing themselves on a railing or wall to conserve energy—a trick most humanoids can't perform.

Digit in Action: Real-World Deployment and Pilots
The Flagship Partnership: Amazon Digit Pilots
In 2024, Agility Robotics announced a major partnership with Amazon to begin testing Digit in its fulfillment centers. The initial pilot involves Digit performing a highly repetitive but essential task: picking up and moving empty totes from a conveyor system to a nearby cart. This is a perfect first application—it's dull and mundane for humans but requires a machine with human-like mobility and manipulation to navigate the space.
Expanding the Footprint: GXO Logistics and Other Partners
Furthermore, logistics giant GXO Logistics, Inc. has also signed on as a partner to deploy Digit in its warehouses. These real-world pilots provide Agility with invaluable data on reliability, maintenance cycles, and operational integration—data that labs simply cannot generate. This head start in commercial deployment is a significant competitive advantage.
The RoboFab: Scaling Production for Demand
Agility is scaling rapidly. They've opened a new factory, "RoboFab," in Oregon, which is intended to be the first large-scale manufacturing facility for humanoid robots.
Commercial Readiness Advantage
While competitors are still demonstrating prototypes in controlled environments, Digit is already solving real business problems. This commercial head start provides Agility Robotics with something competitors lack: real-world operational data that will inform future development and improvements.
