Elaborate any two types of Robots with relevant examples.

Explanation

Human Robot:
Certain robots are made to resemble humans in appearance and replicate the human activities like walking, lifting, and sensing, etc.
(i) Power conversion unit: Robots are powered by batteries, solar power, and hydraulics.
(ii) Actuators: Converts energy into movement. The majority of the actuators produce rotational or linear motion.
(iii) Electric motors: 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. The most often used ones are AC motor, Brushed DC motor, Brushless DC motor, Geared DC motor, etc.
(iv) Pneumatic Air Muscles: Devices that can contract and expand when air is pumped inside. It can replicate the function of a human muscle. They contract almost 40% when the air is sucked inside them.
(v) Muscle wires: Thin strands of wire made of shape memory alloys. They can contract by 5% when electric current is passed through them.
(vi) Piezo Motors and Ultrasonic Motors: Basically, we use it for industrial robots.
(vii) Sensors: Used in task environments as it provides information of real-time knowledge.
(viii) Robot locomotion: Provides the types of movements to a robot. e different types are (a) Legged (b) Wheeled (c) Combination of Legged and Wheeled Locomotion (d) Tracked slip/skid.
Industrial Robots:
(i) Cartesian
(ii) SCARA
(iii) Cylindrical (iv) Delta.
(v) Polar.
(vi) Vertically articulated
