Expert Solution

Yes, sensor and actuator location flexiblity is important for observation and control. The main objective of sensor is to detect motion of actuator and communicate with rest of system. The position and orientation of sensors are vital for sensing actuator motion from required angle, distance, speed and with minimum possible error. Flexiblity between sensor and actuator is noting but maximum coverage with minimum errors by sensor from its location at all times. While deciding sensor location , all actuator actions should be considered.  

Consider example of alarm system with infrared lights. The light position must be such that it covers maximum area with minimum chances of entry for burglar (as in movies!). The sensors should be located such that despite failure of few sensors, system works efficiently. The other external issues for sensor location may be environmental like rain, snow or high solar glair, reach of childrens/pets etc which can damage system.
