中文
含义
左侧驱动轮异常。左轮无法转动、转速异常或悬挂系统卡死，机器人无法正常直线行走。
常见原因
- 左侧驱动轮被长头发或地毯纤维缠绕卡死
- 轮轴内积聚砂石或尘土导致机械阻力过大
- 左侧轮悬挂弹簧卡住导致轮子无法着地
- 轮速编码器/霍尔传感器脏污导致速度反馈异常
- 左轮电机驱动电路异常导致轮速与右轮不一致
自助排查
- 取出左侧驱动轮，清理轮轴上的毛发和纤维缠绕
- 检查轮子是否能自由旋转——如有卡滞需清洁轴腔
- 检查悬挂系统——按压轮子应能弹性回弹
- 清除轮编码器（传感器槽）内的灰尘
- 清洁后手动测试左右轮转动阻力应一致
English
Meaning
Left drive wheel anomaly. The left wheel cannot rotate, rotates abnormally, or the suspension is stuck — preventing straight-line movement.
Common Causes
- Left drive wheel wrapped with long hair or carpet fibers
- Sand or dust accumulated inside the wheel axle increasing mechanical resistance
- Left wheel suspension spring jammed, preventing the wheel from making floor contact
- Dirty wheel encoder or Hall effect sensor causing inaccurate speed feedback
- Faulty left wheel motor driver circuit causing speed mismatch with the right wheel
Self-Check Steps
- Remove the left drive wheel and clear all hair and fiber buildup from the axle
- Check that the wheel spins freely — if binding, clean the axle cavity thoroughly
- Inspect the suspension — pressing the wheel should spring back smoothly
- Clean dust from the wheel encoder sensor slot
- After cleaning, manually spin both wheels — resistance should feel equal left and right
