The word robot was invented in the 20th centuryand comes from the Czech word robota.A machine capable of carrying out a complexseries of actionsautomatically, programmable, that is to say, amachine resembling a human being and able toreplicate certain human movements andfunctions automatically.What is a robot?
A robot consists ofelectric, electronic andmechanical.The Robots are very good forcertain functions, becauseunlike humans never gettired, or fatigued and canwork in dangerousconditions, without air andwithout the easily distracted.What is a robot?
Parts of a robotRobot arms:Robots arms can vary in size and shape. The robot arm isthe part that permit that the robot can move freely. Withthe robot arm, the shoulder, elbow and wrist move andtwist to the exact position. A simple robot with threedegrees of freedom can move in three ways: up &down, left & right, and forward & backward.Sensors:Sensors allow the robot to receive feedback about itsenvironment. The sensor collects information and sends itto the robot controlled. One use of these sensors is to keeptwo robots that work closely together from bumping intoeach other. Sensors can also assist end parts by adjustingfor part variances. Vision sensors allow a robot todifferentiate between items to choose and items to ignore.
Parts of a robotThe end part:The end part connects to the robots arm andfunctions as a fingers of a hand. This part comesin direct contact with the material the robot ismanipulating. Some variations of an effector area gripper, a vacuum pump, magnets, and weldingtorches.The controller:The controller is the "brain“ of the robot andallows the parts of the robot to operate together.The controller gives instructions written in codecalled a program.
Parts of a robotThe drive:The drive is the engine that moves thearticulations into their designated positions. Thejoints are the sections between the parts of therobot. The following types of units are:hydraulic, electric, or pneumatic.o Hydraulic drive systems give a robot greatspeed and strength.o Electric system provides a robot with lessspeed and strength.o Pneumatic drive systems are used for smallerrobots that have fewer axes of movement.
Types of industrial robotsA type of robotic armthat has prismatic jointsonly. The linearmovement of the jointsgives the Cartesianrobot a highly rigidstructure that allows itto lift heavy objects.Cartesian Robot
Types of industrial robotsUsed for assembly operations, handling atmachine tools, spot welding, and handling at die-casting machines. Its a robot whose axes form acylindrical coordinate system.Cylindrical Robot
Types of industrial robotsUsed for handling at machine tools, spotwelding, die-casting, fettling machines, gaswelding and arc welding. Its a robot whose axesform a polar coordinate system.Spherical / Polar Robot
Types of industrial robotsUsed for pick and placework, application ofsealant, assemblyoperations andhandling machinetools. Its a robot whichhas two parallel rotaryjoints to providecompliance in a plane.Scara Robot
