含义
机器人内置陀螺仪/IMU（惯性测量单元）传感器信号异常，影响机器人的方向判断、直线行进和路径规划能力。
常见原因
- 陀螺仪传感器受到强烈外力撞击导致内部结构偏移
- 传感器焊接点因振动出现虚焊，信号时断时续
- 传感器受强磁场干扰（如靠近大功率音箱、微波炉）
- 陀螺仪校准数据丢失或初始化失败
- 机器人被抬离地面搬运后传感器未完成重新校准
自助排查
- 将机器人放置在平坦水平地面，关闭电源后重新启动
- 确保机器人远离强磁场源和大型金属物体
- 尝试在App中执行IMU传感器校准（如可用）
- 启动机器人用手辅助引导前进一小段距离，帮助传感器重新标定
- 若机器人一直在原地打转或行进轨迹严重偏斜，且校准无效，需更换IMU模块
English
Meaning
The robot’s built-in gyroscope/IMU (Inertial Measurement Unit) sensor signal is abnormal, affecting the robot’s direction sensing, straight-line travel, and path planning ability.
Common Causes
- Strong physical impact causing internal structural shift in the gyro sensor
- Vibration-induced cold solder joints on the sensor, causing intermittent signal
- Strong magnetic field interference (near high-power speakers, microwave ovens)
- Lost gyroscope calibration data or initialization failure
- Robot carried and relocated without completing sensor re-calibration after placement
Self-Check Steps
- Place the robot on a flat, level surface, power off, then restart
- Ensure the robot is away from strong magnetic sources and large metal objects
- Try running IMU sensor calibration from the app (if supported)
- Start the robot and manually guide it forward a short distance to help sensor re-calibration
- If the robot spins in place or its travel path is severely skewed and calibration does not help, replace the IMU module
