There are many different varieties of industrial robots
, but the basic concept remains the same. It consists of a stable supporting frame, ensuring the secure stance of the robot. Housing contains the drive and operating technology. Robots use the same drive technology that common in industry. There are pneumatic, electric and hydraulically driven robots, which rely on the same supply engineering as the other machinery. The majority of industrial robots
are electrically driven. Pulling cables or specialised kinematics (e.g., SCARA robots) compensate for the speed disadvantage of electrically driven robots. The actual gripping and moving unit of the robot is called the manipulator, referred to informally as the "robot arm". This is the main differentiation between the different types of robots; robots are defined by their movable axels. Though axels are theoretically customizable, the 5-axel-robot is the common manipulator
for industrial use.
