Released: 2024

Overview

Digit V4 represents Agility Robotics' fourth generation of bipedal humanoid robots, purpose-built for the demands of modern logistics and warehouse environments. Drawing on years of research in legged locomotion and practical deployments with partners like Amazon, Digit V4 embodies a refined approach to mobile manipulation that leverages the advantages of a human-like form factor to navigate spaces designed for people.

The robot's design philosophy centers on practical commercial deployment rather than research experimentation. Every aspect of Digit V4—from its modular end-effectors to its improved battery system—has been engineered to maximize uptime, reliability, and integration with existing warehouse management systems. The bipedal configuration allows Digit to traverse stairs, step over obstacles, and work in environments with varied terrain without requiring infrastructure modifications.

Digit V4 builds on proven technology with enhancements focused on durability, serviceability, and operational efficiency. The robot features a more robust chassis, improved actuators for consistent performance, and enhanced sensing capabilities that enable safer human-robot collaboration in shared workspaces.

Key Features

Bipedal locomotion: Human-like walking enables navigation of stairs, curbs, and uneven surfaces in existing facilities
Enhanced payload capacity: 16 kg carrying capacity suitable for tote handling and package manipulation
Modular end-effectors: Interchangeable grippers and manipulation tools adapt to different tasks and workflows
Extended battery life: 2-4 hours of continuous operation with hot-swappable battery system for minimal downtime
Advanced perception: Multi-modal sensor suite including LiDAR and cameras for navigation and object detection
Fleet management integration: Built-in connectivity for coordination with warehouse management systems and multi-robot orchestration
Human-centric design: Operates safely in shared spaces with collision avoidance and compliant control

Applications

Digit V4 is primarily deployed in logistics and e-commerce fulfillment operations where its bipedal mobility provides distinct advantages. The robot excels at tote moving, package sorting, and material transport tasks within warehouses and distribution centers. Major logistics providers and retailers have begun pilot programs using Digit for repetitive material handling tasks, freeing human workers to focus on more complex activities requiring judgment and dexterity.

Beyond traditional warehousing, Digit V4 shows promise in manufacturing environments for line-side delivery, inventory management, and inter-facility transport. The robot's ability to navigate mixed indoor-outdoor environments and handle varied terrain makes it suitable for campus logistics at universities, hospitals, and corporate facilities where goods must move between buildings through spaces designed for pedestrian traffic.

Technical Highlights

Digit V4's bipedal locomotion system represents years of refinement in dynamic balance and gait control. The robot employs sophisticated model-predictive control algorithms that enable stable walking across varied surfaces while carrying payloads. This control system allows Digit to recover from disturbances, adapt to unexpected obstacles, and maintain stability even when pushed or bumped—critical capabilities for safe operation in active work environments.

The robot's modular architecture facilitates rapid maintenance and customization for specific workflows. Standardized mechanical and electrical interfaces enable quick end-effector changes without specialized tools, while the sensor suite provides 360-degree perception for autonomous navigation and obstacle avoidance. Agility Robotics has focused extensively on the software stack, providing APIs and integration tools that allow customers to incorporate Digit into existing automation ecosystems and fleet management platforms.
