← TechnologyWhich error accumulates calculating robot joint angles via inverse kinematics when the encoder has low resolution?
A)Positional deviation at the end-effector✓
B)Overcurrent in servo motor windings
C)PLC program execution halts unexpectedly
D)Unintended motor speed oscillation frequency
💡 Explanation
Low encoder resolution reduces the precision with which joint positions are known, causing accumulated errors in the inverse kinematics calculations. Therefore, the end-effector deviates from its desired position, rather than issues with servo-motor or program behavior, because the resolution affects the calculations.
