"All robots are machines, but all machines are not robots." Prepare a write-up on the same.

All robots are machines because they are electromechanical devices designed to perform specific tasks using mechanical parts, electronic components, and computer programs. Robots are capable of sensing their environment, processing information, and performing actions either autonomously or with minimal human intervention.

However, all machines are not robots. A machine is any device that helps humans perform work more easily, such as a fan, washing machine, or calculator. These machines work only according to fixed instructions and do not have sensors, decision-making ability, or adaptability. They cannot sense the environment or make decisions based on inputs.

Robots, on the other hand, can process sensor data, make decisions, and adapt to changes in their surroundings. Therefore, while every robot is a machine, every machine cannot be called a robot, which justifies the statement.
