Both statements I and II are incorrect.
Reason — Statement I is incorrect because every robot is a machine, but every machine is not a robot. An ordinary machine, such as a room heater, has no sensors, controller or decision-making ability.
Statement II is also incorrect because robots can work autonomously, that is, without human intervention, as well as with the support of humans. For example, a self-driving car is an autonomous vehicle that can operate without a human driver.
