含义
左侧驱动轮被卡住无法正常旋转或转动阻力超过设定阈值，机器人无法正常前进或转向。
常见原因
- 左侧驱动轮缠绕大量毛发或线缆，物理卡死
- 左侧轮轴处卡入小硬物（小石子、坚果碎屑）
- 左侧驱动轮减速齿轮箱内齿轮打齿或碎裂
- 左侧轮子胎面磨损严重，与地面摩擦力异常
- 悬挂弹簧卡滞导致轮子无法正常浮动静音
自助排查
- 翻转机器人，检查左侧驱动轮周围是否有毛发缠绕
- 用手左右旋转左侧驱动轮，评估转动阻力
- 用镊子或小剪刀清理轮轴缝隙间的缠绕物
- 转动左侧轮子并对比右侧轮子——左侧应同样灵活
- 若左侧轮子明显比右侧紧或完全卡死，需拆解轮组检查齿轮箱
English
Meaning
The left drive wheel is jammed and cannot rotate normally, or the rotational resistance exceeds the set threshold. The robot cannot move forward or turn properly.
Common Causes
- Left drive wheel heavily tangled with hair or cable, physically locked
- Small hard object (small stone, nut fragment) lodged in the left wheel axle
- Stripped or broken gears inside the left drive wheel gearbox
- Severely worn left wheel tread causing abnormal ground friction
- Suspension spring stuck, preventing the wheel from floating freely
Self-Check Steps
- Flip the robot over and inspect the left drive wheel for hair tangles
- Rotate the left drive wheel by hand in both directions to assess resistance
- Use tweezers or small scissors to clear debris from the wheel axle gaps
- Compare left wheel rotation smoothness against the right wheel — both should move equally freely
- If the left wheel is noticeably tighter than the right or completely seized, disassemble the wheel assembly to inspect the gearbox
