What is a Robot Control System? Having only sensors and muscles is not enough for human limbs to move. On one hand, sensory signals need organs to receive and process them; on the other hand, there are no organs to send neural signals that drive muscle contraction or relaxation. Similarly, if a robot only has … Read more
