Robots
⭐ MasteredRobots are machines programmed to do tasks. They use sensors to sense the world and motors to move.
Some robots explore Mars.
All about Robots
A robot is a machine that can carry out tasks automatically. Many robots are programmed to follow instructions, and some can sense their surroundings and react. Robots work in factories, hospitals, farms and even space.
Robots use sensors, such as cameras, touch sensors and distance detectors, to understand the world. They use motors and actuators to move, and a computer program to decide what to do next. Some robots are controlled by people, while others work independently.
Robots are programmed, which means their behaviour is set by code. Most robots have three main parts: sensors that detect the world, a computer that decides what to do, and motors or other parts that move.
Some robots can clean floors or deliver food. Robots are helpful because they can repeat tasks accurately and work in places that are dangerous for people.
