Technology

Which risk significantly increases when encoder resolution limits exist in a robot's joint position sensor?

A)Increased steady-state position errors
B)Reduced motor drive thermal stress
C)Decreased PLC program execution time
D)Enhanced computational inverse kinematics

💡 Explanation

Increased steady-state position errors occur because quantization error, stemming from the limited encoder resolution, manifests as inaccuracies the position feedback loop. Therefore, the robot struggles to achieve exact desired joint angles, rather than more efficient thermal or faster inverse kinematic solves.
