Which risk is amplified if a hydraulic actuator in a robotic arm experiences stick-slip friction?

💡 Explanation

When stick-slip friction occurs, the actuator alternates between static friction and kinetic friction because of inconsistent lubrication or surface irregularities, causing jerky movements and imprecise positioning. Therefore, positional inaccuracy and overshoot results, rather than temperature increase, pump wear, or reduced load, which involve different failure mechanisms.
