"Robots are flexible mechanical machines." Justify this statement.

Robots are called flexible mechanical machines because they are designed with links, joints, actuators, and controllers that allow them to perform a wide variety of tasks. Robots can change their position, direction, and movement according to the task requirements. They can be reprogrammed to perform different operations without changing their physical structure. Due to their flexibility, robots can be used in different environments and applications such as manufacturing, medical surgery, transportation, and space exploration. This ability to adapt and perform multiple tasks makes robots flexible mechanical machines.
