含义
右侧驱动轮被卡住无法正常旋转或转动阻力超过设定阈值，机器人在行进中可能出现原地打转或单侧不动。
常见原因
- 右侧驱动轮缠绕毛发、线缆或地毯纤维
- 右侧轮轴异物卡入（碎玻璃、金属片、硬塑料片）
- 右侧驱动轮电机编码器信号异常，控制板误判为卡住
- 右侧轮子悬挂机构卡滞，轮子无法接触地面
- 右侧轮子胎面与驱动轮毂脱胶分离
自助排查
- 翻转机器人，仔细检查右侧驱动轮的轮槽和轴心区域
- 清除右侧轮子上所有可见缠绕物
- 用手快速拨动右侧驱动轮，听是否有异常摩擦声
- 清洁轮子两侧的编码器开槽（如可见）
- 如果清理后E03仍然存在且右侧轮转动异常，需更换右侧驱动轮模块
English
Meaning
The right drive wheel is jammed and cannot rotate normally, or the rotational resistance exceeds the set threshold. The robot may spin in place or drag one side during operation.
Common Causes
- Right drive wheel tangled with hair, cable, or carpet fibers
- Foreign object (glass shard, metal piece, hard plastic) lodged in the right wheel axle
- Abnormal right wheel motor encoder signal causing the control board to falsely detect a jam
- Right wheel suspension mechanism stuck, preventing wheel-to-ground contact
- Right wheel tread separated from the drive hub due to adhesive failure
Self-Check Steps
- Flip the robot over and carefully inspect the right drive wheel well and axle area
- Remove all visible debris wrapped around the right wheel
- Spin the right drive wheel rapidly by hand and listen for abnormal scraping sounds
- Clean the encoder slots on both sides of the wheel if accessible
- If E03 persists after cleaning and the right wheel still rotates abnormally, replace the right drive wheel module
