G1 Diagnostics Guide

The G1 robot is a sophisticated system composed of multiple integrated components, including sensors, actuators, and control software. Malfunctions can arise from either hardware faults or software anomalies. When the robot does not behave as expected, it is essential to first isolate and identify the root cause. This guide provides step-by-step instructions for performing initial diagnostics and gathering key information that can be shared with our support team to facilitate effective troubleshooting and assistance.

Behavior Analysis & Inspection​

When the robot does not behave as expected, the first step is to carefully observe its behavior and conduct a visual inspection. We strongly recommend setting up a dedicated workspace with continuous video recording (e.g., surveillance cameras). This is especially useful for capturing intermittent or unpredictable issues that may occur when you're not actively monitoring the system.

If the event was not recorded, you can still examine the robot post-incident for signs of malfunction. Begin with a thorough visual inspection focused on the following areas:

  • Robot Body: Check for any visible damage, such as cracks, dents, or impact marks that may indicate collisions or falls.
  • Sensors: Ensure all sensors are clean, unobstructed, firmly mounted, and properly connected. Dust or misalignment can cause degraded performance.
  • Cables and Connectors: Inspect for loose plugs, frayed wires, or damaged insulation. Confirm that all connections are secure and seated properly.
  • Battery: Look for signs of swelling, leakage, or deformation. Ensure the battery is correctly installed and shows no abnormal wear.
  • LED Indicators: Observe status LEDs for abnormal colors or flashing patterns, which may signal internal errors or system faults.

Mobile App Diagnostics Data​

You may also use the Unitree mobile app to check the robot's diagnostic information. You can download the Unitree mobile app with the QR code on this page:

To acquire the robot's diagnostic information, you need to connect your mobile device to the robot first. G1 supports both AP mode and WiFi mode. Unitree provides a tutorial video for using WiFi mode. The following screenshots quickly guide you through the process of connecting to the robot using AP mode.

Reporting the Issue​

When reaching out to our support team, please provide a structured and detailed account of the problem. Please consider the following questions when reporting the issue:

  • What actions or commands were executed just before the issue occurred?
  • How did the robot behave during and immediately after the incident?
  • Were there any error messages, warning tones, or abnormal movements?
  • Are there any visible signs of physical damage or wear?

Please attach screenshots taken from the mobile app, including diagnostic data and alarm information. If available, include relevant video footage. This helps us understand and reproduce the issue more effectively.

Understanding and documenting the issue clearly will help prevent further damage and ensure safe continuation of your development or testing efforts.
