← TechnologyWhich control error arises when a robotic arm's joint position calculation exceeds the encoder's sensor bit-depth?
A)Quantization noise becomes significant✓
B)Inaccurate transmission gear meshing
C)Thermal drift accumulates rapidly
D)Backlash compensation becomes amplified
💡 Explanation
Increased position error occurs because the analog-to-digital converter produces substantial quantization noise when resolution is exceeded; therefore, significant errors appear rather than gradual degradation owing to other noise sources and modeling uncertainties.
