Question
Technology

Which outcome occurs when a differential pressure sensor on a robotic arm's pneumatic actuator gives a sporadically low reading?

A)Compromised force control accuracy
B)Unexpected joint velocity increase
C)Encoder signal phase shift
D)System-wide thermal instability

💡 Explanation

Compromised force control accuracy results because the PID controller uses the erroneous sensor feedback; the integral windup compensation fails, rather than maintaining positional accuracy because the pressure calculation is incorrect, therefore leading actuators operating off values.
