问答题Basically, a robot is any machine that performs work or other actions normally done by humans. Most robots are used in factories to make products such as cars and electronics. Others are used to explore underwater, in volcanoes and even on other planets.
Robots consist of three main components: a brain, which is usually a computer; actuators and mechanical parts such as motors, wheels and gears; and sensors for detecting images, sound, temperature, motion and light. With these basic components, robots can interact with their environment and perform the tasks they are designed to carry out.
