Technology

Which consequence results when excessive vibrations disrupt the MEMS gyroscope in a robotic arm's inertial measurement unit?

A)Motor overheating becomes more likely
B)Positional drift becomes more pronounced
C)Encoder resolution improves marginally
D)Back-EMF voltage reduces significantly

💡 Explanation

Positional drift increases because excessive vibrations induce noise into the gyroscope output, which gets integrated into the estimated angular velocity; small errors accumulate over time through the integration. Therefore, positional accuracy drifts, rather than other motor faults occurring under such conditions.
