Answer:
The robot has several inputs for speech recognition and sight like a microphone (as its ears) and cameras for sight. The robot has neural networks of programmed instructions in its processor which is used to process data received from the input devices and the result comes out as a response (like the robot speaking with a speaker as its mouth). This clearly defines the robot as a computer system.
Step-by-step explanation:
A computer system is an electronic device that accepts input from a user or its surrounding, processes the data received and returns the output of the processed data.
The robot is able to receive data, process the data with its processor and responds or sends feedback to the user.
