capable of performing complex tasks.
Join us on a riveting journey as we dive into the fascinating world of
Robotics, uncovering its history, inner workings, remarkable features, and
the boundless potential it holds for various industries.
What is Robotics:
Robotics is a multidisciplinary field that involves the conception, design,
manufacture, programming, and operation of robots.
It combines elements of mechanical engineering, electrical engineering,
computer science, and artificial intelligence to create intelligent machines
capable of interacting with the physical world.
The main objective of robotics field is to create intelligent machines that
can help human in various ways.
Full form of ROBOT is “Random Optical Binary Oscillating Technology”.
History of Robotics:
The origins of Robotics can be traced back to ancient times when inventors
and thinkers conceptualized mechanical devices.
The word robotics was derived from the word robot, which was introduced
to the public by Czech writer Karel in his play R.U.R (Rossum’s Universal
Robots), which was published in 1920.
The word robot comes from the Slavic word robota, which means work/job.
According to the Oxford English Dictionary, the word robotics was first used
in print by Issac Asimoy, in his fiction short story “Liar!”, published in May
1941 in Astounding Science Fiction.
Other significant milestones include
1. The development of the first programmable machine by Jacques de
Vaucanson in the 18th century,
2. The creation of the first industrial robot by George Devol and Joseph
Engelberger in the 1950s, and
3. The emergence of advanced humanoid robots like ASIMO by Honda
in the early 2000s.
The first digitally operated and programmable robot, the Unimate, was
installed in 1961 to lift hot pieces of metal from a die casting machine and
stack them.
How Robotics Works:
Robots operate through a combination of hardware, software, and sensors.
The hardware includes mechanical components, such as arms, legs, and
grippers, while the software comprises algorithms that govern their
behavior.
Sensors enable robots to perceive and interact with the environment,
allowing them to make informed decisions and adapt to changing
conditions.
The most popular language in robotics is C/C++ and python. Python
language is quite useful for ROS (Robot Operating System). As Python is
used in machine learning as well along with Raspberry Pi, it’s usage in
Robotics in quite significant.
Components of Robots:
These are the main components of Robots.
1. Control Systems: They form the main part of Robots and tell a robot
how to utilize its other components,
2. Sensors: They help robots to sense and interact with the outside
surroundings. Sensors can be in the form of video camera,
microphone etc.
3. Actuators: These related to movable components of a robot. They
receive signal from the control system and carry out the defined task.
4. Power: Many robots operate via battery or some other energy
device.
5. Effectors: These are the physical, external components that allow
robots to finish carrying out their tasks.
Important Features of Robotics:
a) Sensing and Perception: Robots utilize sensors, such as cameras,
LIDAR, and proximity sensors, to perceive their surroundings and
gather information about the environment.
b) Autonomous Decision Making: Advanced robots employ artificial
intelligence and machine learning algorithms to analyze data, make
decisions, and adapt their actions based on changing circumstances.
c) Manipulation and Mobility: Robots are equipped with mechanical
components and actuators that enable them to manipulate objects,
move in various environments, and perform tasks with precision and
dexterity.
Types of Robotics
1. Pre-programmed Robots: They operate in a controlled environment.
They are used to carry out simple, monotonous tasks. We can see
example of these in manufacturing and automobile sector.
A pre-programmed robot can act as a mechanical arm and perform a task
say, welding or inserting a part in the engine or moving some pieces from
one place to another.
2. Humanoid robots: They look like a human. They are designed to
resemble humans, with the ability to walk, talk, and interact with their
surroundings, blurring the line between humans and machines.
3. Autonomous robots: They operate independently of human operators.
These robots complete the assigned task, without any human
intervention.
4. Teleoperated robots: These are semi-autonomous bots that use a
wireless network to enable human control from a safe distance.
5. Augmenting robots: They either enhance current human capabilities
or replace the capabilities a human may have lost.
They are used in medical field, to provide prosthetic limbs or
exoskeletons.
6. Collaborative Robots: Known as cobots, these robots work alongside
humans, assisting with tasks and enhancing productivity in industries
such as manufacturing and healthcare.
7. Swarm Robotics: Robots can work together in a coordinated manner,
like a swarm of bees, to accomplish complex tasks more efficiently
and quickly than a single robot.
8. Industrial Robot: This robot system is used in manufacturing
industries.
9. Nano-Robots: They have nanometer scaled dimensions and can
handle or work in a environment with nanometer scale resolution.
10. SCARA Robotics: It’s a type of industrial Robot. Here SCARA
stands for ‘Selective Compliance assembly Robot Arm’.
11. Micro-robots: These are miniature robots. Mobile robots, with
dimension less than 1 mm. These robots are capable of handling micrometer size components.
Advantages of Robotics:
