The definition of robots ranges from industrial robots that are serviced by factories to robots that are cleaned at home. According to the broadest definition at the moment, if something is considered by many to be a robot, then it is a robot. Many robotics experts (people who make robots) use a more precise definition. They stipulate that robots should have a reprogrammable brain (a computer) that can be used to move the body. According to this definition, robots differ from other mobile machines (such as cars) in their computer elements. Many new cars have an onboard computer, but only use it to make minor adjustments. The driver directly controls most of the components of the vehicle through various mechanical devices. Robots are different in physical properties from ordinary computers, each of which is connected to a body, whereas ordinary computers do not.

Most robots do have some common characteristics

First of all, almost all robots have a body that can move. Some have motorized wheels, while others have a large number of moving parts, which are usually made of metal or plastic. Similar to human bones, these separate components are articulated. The wheel and shaft of the robot are connected by some kind of transmission. Some robots use motors and solenoids as transmissions; others use hydraulic systems; others use pneumatic systems (systems driven by compressed gas). The robot can use any of the above types of transmissions. Second, the robot needs an energy source to drive these transmissions. Most robots use a battery or a wall outlet to power. In addition, hydraulic robots require a pump to pressurize the liquid, while pneumatic robots require a gas compressor or a compressed gas cylinder. All transmissions are connected to a circuit by wires. The circuit supplies power directly to the electric motor and solenoid and operates an electronic valve to activate the hydraulic system. The valve controls the path through which the pressurized fluid flows within the machine. For example, if the robot is to move a hydraulically driven leg, its controller opens a valve that is passed from the hydraulic pump to the cylinder on the leg. The pressurized fluid will push the piston and rotate the leg forward. Typically, robots use a piston that provides two-way thrust to allow components to move in both directions.
