A robot is a machine that is capable of carrying out a complex series of actions automatically, especially one programmable by a computer. Robots are often used in industrial settings to perform tasks that are dangerous or repetitive. They can also be used in healthcare, space exploration, and other fields.
The main difference between a car and a robot is that a car is a vehicle that is controlled by a human driver, while a robot is a machine that is capable of operating independently. Robots can be programmed to perform a variety of tasks, while cars are only designed to transport people or goods.
