Robotics is almost as ancient as Christ and Greek civilisation, starts off Dr. Vasudev K. L. (Department of Mechanical Engineering, Amrita). Founded as way back as 350 BC by Greek mathematicians, Robotics finds its roots in history all over the world, from Sanskrit treatise to the inventions of Leonardo Da Vinci. Modern robots have progressed on from the traditional ones to find applications in industries and the current day demand of the same has led to the development of courses specifically targeted to planning, building and implementing robotic functions in both corporate and personal lives.

Robotics has its base in three laws, titled as the laws of robotics, explains Dr. Vasudev. With three laws, there is also a zeroth law that was added upon consideration at a later stage. With law zero stating that no adverse effects on humanity should be ensured by robotic applications, law one adds a condition of exception for the same, i.e., when it prevents greater harm to humanity.

Law 2 states that robots should always abide by human laws, except for situations when it conflicts with the above laws. Last law talks about how robots should protect itself given a higher law is not being breached.

Robots feature various human characteristics like the five senses, movement, energy storage and intelligence. To bring all of these characteristics in a robot, a strong knowledge base is important. Herein, we need engineers who are experts in dynamic system modelling and analysis, feedback control, sensor and signal conditioning, computer programming, hardware interfacing and power electronics.

Robots also involve many components like actuators, power supply, muscle wires, motors, and sensors that contribute to its effective working. While a robot base can be either fixed or moveable based on its application, various sensors that duplicate human sensing capability are used to add to its functionality – vision sensors, force sensors, tilt sensors and many more.

There are also end effectors that manage other functions like connecting and running of the robot in a stable environment. Actuators, power supply, controllers and user interfaces comprise of the final set of parts to complete a robot. With applications in tasks in all prominent sectors, AI based robots of all shapes and sizes are the future of humankind. Career prospects in this field are hence sure to grow and evolve in the coming years, making an engineering specialisation in robotics becoming a highly-valued addition to build a career.

Ancient vs Modern Robots

Robots have been an age-old science, dating back to AD times, says Dr. Vasudev K. L. With ancient robots used for simple applications, modern robots will have more functionality mimicking human actions with more precision.

Laws of Robotics

Dr. Vasudev explains on the 3 + 1 Laws of Robotics, with the zeroth law an addition of the former three. Law 1-3 guard humanity and set rules of robotic operations in all situations while abiding by the higher order laws.

What Is Robot And Its Application

Robotics have various components and all components find applications in various sectors. With its applications being widespread over various corporate applications, the field is evolving into more with each passing day, adds Dr. Vasudev.

Applications And Future Scope Of Robotics

The future of Robotics will surely be led by Artificial Intelligence, highlights Dr. Vasudev. With robots of all sizes and types, smart and intelligent to carry out all tedious tasks currently managed by humankind, the applications are also going to increase manifold, he adds.
