← TechnologyWhich corrective action does dead reckoning prevent, when a robotic arm moves to a location under heavy load?
A)Cumulative positional calculation errors✓
B)Unpredictable motor burnout patterns
C)Sensor degradation induced by pressure
D)Electromagnetic interference with joint control
💡 Explanation
Dead reckoning uses incremental movements with sensor feedback, limiting cumulative error, rather than absolute positioning each time. Therefore it reduces accumulating position errors; rather than motor burnout (electric), pressure-related degradation (material), or signal interference (electrical) that are separate effects.
