George Devol and Joseph Engelberger, the father of the modern robotics industry formed the world’s first robot company in . In , Unimate, was operated in a General Motors automobile factory for moving car parts around in New Jersey. - - - - Unit Recent developments in physics Most robots are composed of main parts: .
Te Controller ‐ also known as the "brain" which is run by a computer program. It gives commands for the moving parts to perform the job. . Mechanical parts - motors, pistons, grippers, wheels, and gears that make the robot move, grab, turn, and lif.
. Sensors - to tell the robot about its surroundings. It helps to determine the sizes and shapes of the objects around, distance between the objects, and directions as well. .
Power conversion unit: Robots are powered by batteries, solar power, and hydraulics. . Actuators: Converts energy into movement. Te majority of the actuators produce rotational or linear motion.
. Electric motors: Tey are used to actuate the parts of the robots like wheels, arms, fingers, legs, sensors, camera, weapon systems etc. Different types of electric motors are used. Te most ofen used ones are AC motor, Brushed DC motor, Brushless DC motor, Geared DC motor, etc.
. Pneumatic Air Muscles: Tey are devices that can contract and expand when air is pumped inside. It can replicate the function of a human muscle. Tey contract almost % when the air is sucked inside them.
. Muscle wires: Tey are thin strands of wire made of shape memory alloys. Tey can contract by % when electric current is passed through them. .
Piezo Motors and Ultrasonic Motors: Basically, we use it for industrial robots. . Sensors: Generally used in task environments as it provides information of real-time knowledge. .
Robot locomotion: Provides the types of movements to a robot. Te different types are (a) Legged (b) Wheeled (c) Combination of Legged and Wheeled Locomotion (d) Tracked slip/skid HUMAN ROBOT Certain robots are made to resemble humans in appearance and replicate the human activities like walking, lifing, and sensing, etc. Key components Controller Power conversion unit Actuators Sensors Manipulator linkage base User interface
