Unitree A2 dual-sided LiDAR perception

Dual-Sided Perception

Zero Blind Spots. Greater Accuracy.

Two industrial-grade LiDARs mounted front and rear, paired with an HD camera and front spotlight, give the A2 complete 360° environmental awareness. No blind spot means no missed threat — critical for autonomous security patrol in complex facilities.

  • 2× industrial LiDAR (front & rear)
  • HD camera with integrated front light
  • Accurate environment detection at all angles
  • 8-Core CPU + Intel Core i7 onboard compute

Dual Battery System

Hot-Swap Batteries. Unlimited Runtime.

The A2's dual parallel battery design allows seamless hot-swapping — change one battery while the other keeps the robot running. The triple power system remains reliable from −20°C to 55°C, making it mission-ready in any climate, any shift.

  • Dual slots: 2× 9,000 mAh (907 Wh total)
  • Swap without stopping — zero mission interruption
  • Operates from −20°C to +55°C
  • 50.4V supply with local air cooling

FAQ
WHAT DO THE ROBOTS ACTUALLY DO?
Our autonomous robots provide **continuous, mobile monitoring** across your facilities. They patrol predefined routes, capture visual and sensor data, and detect anomalies such as **unauthorized access, safety risks, or operational irregularities**. Instead of relying on static cameras, they create a **dynamic layer of visibility**, feeding real-time insights into a centralized system that enables faster, more informed decision-making.
WHERE CAN THE ROBOTS BE USED?
The robots are designed for **large-scale industrial and commercial environments**, including manufacturing plants, logistics hubs, office campuses, and retail complexes. They are particularly effective in areas with **limited visibility, large perimeters, or complex layouts**, where traditional surveillance or manual patrols struggle to provide consistent coverage.
HOW DO THEY IMPROVE SECURITY COMPARED TO CAMERAS?
Traditional cameras are **fixed and limited by placement**, which creates blind spots and gaps in coverage. Our robots introduce a **mobile, always-on presence** that adapts to your environment. This means you gain **continuous coverage, fewer blind spots, and real-time situational awareness**, all while enhancing the effectiveness of your existing security infrastructure rather than replacing it.
WHAT ARE THE MAIN BUSINESS BENEFITS?
Organizations typically see **improved coverage, faster incident response, and reduced reliance on manual patrols**. This leads to **lower operational costs** and more efficient use of security teams. Beyond security, the system also provides **data-driven insights** that help optimize operations, identify recurring risks, and support better decision-making across sites.
HOW DOES THE PILOT WORK?
We start with a short alignment session to understand your **facilities, priorities, and risk areas**. Based on this, we deploy robots on-site for a defined pilot phase. During the pilot, you’ll experience **real-world performance, measurable impact, and direct feedback from your team**, allowing you to evaluate the solution before making a broader rollout decision.
HOW QUICKLY CAN WE GET STARTED?
Most pilots can be launched within **a few weeks**, depending on site readiness. The system is designed for **fast deployment with minimal infrastructure changes**, so you can start seeing value quickly. From there, scaling to additional locations is straightforward, enabling a **phased rollout aligned with your operational priorities**.
