Last time
Before we start: last time, in Automated systems, you learned these points. Here they are again on one card. Keep them in mind, because today builds on them.
Machines that move
Some machines only think. Others think and move. A robot vacuum cleaner drives round your living room. A factory arm welds a car. What makes a machine a robot, and not just a computer? There are three characteristics, and Cambridge asks for them by name.
Robotics and robots
Robotics is the branch of computer science that deals with robots. It covers how robots are designed, built and operated. A robot is a programmable machine that carries out a series of tasks automatically.
Three characteristics
First, a mechanical structure, or framework: a body, with arms, joints, wheels or grippers. Second, electrical components: sensors, a microprocessor and actuators. Third, it is programmable: its program can be changed, so it can do different tasks. A machine needs all three, to count as a robot.
Is it a robot?
A robot vacuum cleaner has a body with wheels, it has sensors and a microprocessor, and it is programmed. It is a robot. A smart speaker has electrical components and is programmable, but it has no mechanical structure. It cannot move, so it is not a robot.
