← TechnologyWhich effect occurs when robotic arm PLCs output conflicting joint angles?
A)Harmonic drive gear tooth jamming
B)Increase in encoder signal noise
C)Unexpected link path deviations✓
D)Thermal overload on servomotor windings
💡 Explanation
Robotic arms rely on coordinated joint motion; conflicting joint angle result in trajectory errors because inverse kinematics transformations do not converge on a consistent path. Therefore link deviations occur rather than the other effects like gear jam, encoder failure, or thermal overload alone.
