Which of the following is NOT one of the three basic parts of a robot?

The three basic parts of a robot are typically understood to be the manipulator, the power supply, and the system controlling the robot.

The manipulator is responsible for performing tasks and interacting with the environment, essentially functioning as the robotic arm or hand. The power supply provides the energy necessary for the robot to operate, while the system controlling the robot—often a computer or controller—executes commands and coordinates the actions of the manipulator and other components.

In contrast, a sensor array, while important for many robotic systems, is not considered one of the essential three parts. Sensors help a robot perceive its environment by providing data about conditions such as distance, temperature, and light, which are crucial for informed decision-making and interaction with surroundings. However, they are not foundational elements in the way that manipulators, power supplies, and control systems are recognized. Thus, identifying the sensor array as not being one of the three basic components aligns with this framework.
