In the app, forget the robot's Wi-Fi network and go through the setup process again, carefully entering the password. Check if your network has MAC address filtering enabled; if so, you may need to add the robot's MAC address (found in the app's robot info settings) to your router's allow list.
• Bluetooth Pairing Fails: Turn off Bluetooth on your phone and then back on. Power cycle the Alpha 2 Robot. Ensure no other devices are actively connected to the robot's Bluetooth. On your phone, remove any existing pairing record for "Alpha2-XXXX" and try pairing anew.
• App Cannot Find Robot: Make sure the robot is powered on and in range (Bluetooth range is typically 10 meters unobstructed). Close and restart the Jimu Robot app. Check your phone's Bluetooth settings to see if the robot is listed there; if it is, connect from the system settings first, then open the app.

Persistent connectivity problems might require a factory reset of the robot, which is usually done by holding a specific button combination (refer to the manual).

B. Motor Malfunctions

Motor issues often manifest as stiff, jerky movements, a motor that doesn't move, or error messages in the app.

• Motor Stuck or Overheated: Servo motors have built-in protection. If a movement is obstructed (e.g., the robot's limb is held), the motor may lock or shut down to prevent damage. Power off the robot, ensure all joints are free to move, and let it cool down for 15-20 minutes before restarting.
• Uncalibrated Motors: If movements seem inaccurate or one limb is misaligned, the motors may need calibration. In the app's settings menu, look for a "Motor Calibration" or "Adjust Servo" option. The app will guide you through a process where each joint moves to its central "zero" position. Perform this on a flat surface.
• Grinding Noise or Weak Movement: This could indicate physical debris in the gearbox or, rarely, a failing servo. Visually inspect the joint for obstructions. If the problem is isolated to one motor and persists after calibration and reboots, it may require professional service. In Hong Kong, UBTECH typically offers support through authorized retailers or service centers.

Regular maintenance involves avoiding excessive force on the joints and storing the robot in a cool, dry place.

C. Software Glitches

Software issues can range from app crashes to unresponsive robot behavior.

• App Freezes or Crashes: First, close the app completely from your phone's task manager. Ensure your phone's operating system and the Jimu Robot app are updated to the latest versions. Clear the app's cache (in your phone's application settings). If problems continue, uninstall and reinstall the app, then log back into your account—your cloud-saved programs will be safe.
• Robot Unresponsive to Commands: Perform a reboot by holding the power button for 5 seconds to turn it off, then turn it back on. This resolves many temporary software states.
• Program Runs Incorrectly: Check your code for logical errors, such as infinite loops or conflicting motor commands. Simplify the program to isolate the problematic block. Ensure the robot's battery is not low, as low power can cause processors to behave unpredictably.
• Firmware Update Failures: If an update is interrupted, it can cause serious issues. Always update with the robot fully charged and connected to a stable Wi-Fi network. If an update fails, do not power off the robot. The app should provide recovery instructions, which may involve re-downloading the firmware. Contact official support if the robot becomes completely unresponsive after a failed update.

By methodically working through these troubleshooting steps, you can resolve the vast majority of issues and return to enjoying the rich experience offered by your Alpha 2 Robot and the Jimu Cloud ecosystem.
