← TechnologyWhich consequence results when a robotic arm's inverse kinematics solver accumulates quantization errors?
A)Increased motor driver frequency
B)Cumulative endpoint positioning error✓
C)Decreased encoder resolution sensitivity
D)Joint friction coefficients decrease significantly
💡 Explanation
Robotic arms rely on inverse kinematics to compute joint angles for desired positions; if the inverse kinematics solver exhibits quantization error, it results in cumulative endpoint positioning error because the approximation propagates rather than being corrected each cycle; therefore, inaccuracies buildup, not motor changes.
