← TechnologyWhich inaccuracy occurs when robot arm encoders misinterpret vibration?
A)Position reading drift amplifies over time✓
B)Joint motor overheating halts operation
C)Power supply voltage irreparably drops
D)Control system instability leads to oscillations
💡 Explanation
Reading drift occurs at the joint because sensor `aliasing` causes high-frequency vibrations to be interpreted as slow movements. Therefore, apparent position drifts from intended target, rather than causing heat or control instability, because vibration energy is not directly converted.
