Unitree A2 Intelligent Autonomous Charging Dock

Unitree A2

Intelligent Autonomous Charging Dock

Precise Docking, Reliable Runtime

Designed Specifically for A2
Built for unattended operation of the A2 quadruped robot, it integrates autonomous return, tolerance-enabled docking, automatic charging, and multiple safety protections to provide a stable, reliable power supply for inspection, security, and industrial applications.
Automatic Return on Low Battery, Continuous Autonomous Operation
When the battery is low, the robot returns automatically and sequentially completes positioning, posture adjustment, automatic docking, and charging. This reduces manual intervention and replenishes power for extended unattended inspection.
IP56 Protection, Adapt for Challenging Environments
With an IP56 protection rating and an integrated dustproof and waterproof design, the dock supports outdoor deployment.

Concealed Charging Contacts for Safe, Reliable Operation

The charging contacts are concealed inside the dock and are exposed only during the return-to-charge process to establish a charging connection with the robot. This effectively prevents accidental contact by personnel and contamination of the charging contacts, making the dock well suited to a wide range of harsh industrial environments.

40 mm Docking Tolerance for Easy Alignment

Supports approximately 40 mm of alignment error along the X and Y axes, allowing the robot to dock for charging without millimeter-level stopping accuracy. This simplifies autonomous return and docking control and improves recharging adaptability in complex on-site conditions.

Independent Power Control
Easier Operation and Maintenance
Multiple Electrical Protections
Safe Charging
Multiple Positioning Methods,
Flexible On-Site Adaptation
The dock can be equipped with auxiliary positioning components such as reflective posts and QR codes, allowing flexible compatibility with multiple return-to-charge positioning solutions, including LiDAR-based and QR-code-based positioning.
Built-In Storage for Easy Deployment
A built-in storage compartment at the base of the charging dock holds accessories such as QR-code markers, reflective posts, and charging cables, enabling quick deployment and relocation.

Compact All-in-One Design, Seamless Integration

With a hard-surface industrial design, its compact, all-in-one form is refined, visually appealing, and easy to deploy.
