← TechnologyWhich risk dramatically increases when a robotic arm encoder suffers significant backlash?
A)Cumulative positional accuracy degradation✓
B)Motor controller thermal runaway
C)Harmonic drive lubrication failure
D)Power supply voltage oscillations
💡 Explanation
Increased backlash in the encoder causes a discrepancy between measured and actual joint angle positions, feeding errors into the Inverse Kinematics solver because position feedback is inaccurate; therefore positional accuracy sharply degrades with continued movements, rather than other overheating or lubrication risk to adjacent devices.
