The instruments required for perceiving and acting upon the environment are Sensors and Actuators.

Step 1: Perceiving the Environment This is done using sensors. Sensors are devices that detect events or changes in the environment, and then provide a corresponding output. They can perceive various aspects of the environment such as light, temperature, motion, pressure, and more.

Step 2: Acting upon the Environment Once the sensors have perceived the environment, the next step is to act upon it. This is done using actuators. Actuators are devices that move or control a mechanism or system. They take in the information from the sensors and perform an action in the environment based on that information.

So, the correct answer is "Sensors and Actuators".
