ROBOTICS
“Robotics” is the science and technology of Robots, their design, manufacture, and application
The word “Robotics” was first used in print by Isaac Asimov, in his science fiction short story "Runaround" (1941).

History &Development•The word robot was introduced by Czech writer Karel Čapek in his play R.U.R. (Rossum's Universal Robots)
• written in 1920
•derived from the word “Robotovat” which means “to slave” or “to work”
-Leonardo da Vinci (1495) •first recorded designs of a humanoid robot
•early automation - Jacques de Vaucanson(1738)
•humanoid robot known as Elektro
-Westinghouse(1930)

Applications of Robots
![Page 18: 569637 634222725772371250](https://reader033.vdocument.in/reader033/viewer/2022060116/5583a702d8b42a5b318b55a2/html5/thumbnails/18.jpg)
Applications of RobotsManufacturingProbably the industry which uses robots the most. Robots are useful in repetitive tasks and also work for longer durations without breaks.e.g. Robots in car production assembly line
![Page 19: 569637 634222725772371250](https://reader033.vdocument.in/reader033/viewer/2022060116/5583a702d8b42a5b318b55a2/html5/thumbnails/19.jpg)
Applications of Robots
• AgricultureRobots can do
the work that took a dozen harvesters to do at the same time. Robots are used for harvesting, reaping and sowing purposes. They are sometimes called, ‘Agrobots’.

Shortcomings of Robots
1. Are not creative or innovative
2. Do not think independently
3. Do not make complicated decisions
4. Do not learn from mistakes
5. Do not adapt quickly to changes in their surroundings

Terminology
• Artificial Intelligence – The collective attributes of a computer, robot, or other device capable of performing functions such as learning, decision making, or other intelligent human behaviors.
• Autonomous Agent – A hardware (or software) based system that has the following properties:
autonomy - able to operate without the direct intervention of humans or others
social ability - able to interact with other agents and possibly humans reactivity - able to perceive their environment and respond to
changes that occur in it• Agency – A particular system composed of intelligent agents, such as
computers or robots, that cooperate in order to solve a problem.• Behavior Engineering – A methodology used to develop behavior- based
autonomous agents.

Fresh Kitty• Modular, inexpensive, autonomous
mobile robot• 4 wheel toy car design• Max. speed of 1 foot/sec• On-board microcomputer
supervises and supports the exchange of information
• Rotating turret holds 4 sonars • Turret also holds an infrared sensor
to detect infrared rays• 32 light sensors detect objects in
front of the robot• Bumpers all around the robot used
to follow walls• Radio modem to communicate
with remote agents
![Page 25: 569637 634222725772371250](https://reader033.vdocument.in/reader033/viewer/2022060116/5583a702d8b42a5b318b55a2/html5/thumbnails/25.jpg)
SPOT• Autonomous mobile robot• 2 independent wheel design• Max. speed of 1 foot/sec• On-board microcontroller
supervises and supports the exchange of information
• Turret that holds infrared emitters that can be detected at a distance of up to 20 feet
• Bumpers all around the robot used to follow walls
• Radio modem to communicate with remote agents
![Page 26: 569637 634222725772371250](https://reader033.vdocument.in/reader033/viewer/2022060116/5583a702d8b42a5b318b55a2/html5/thumbnails/26.jpg)
How do SPOT and Fresh Kitty work together?
• SPOT also holds a small brush on its back• SPOT finds a wall and uses its bumper system and
sensors to follow edges and collect dust with its brush
• Through radio frequency and infrared communication SPOT can bring the dust back to Fresh Kitty who has a vacuum cleaner waiting to suck it up

RoboCup
• Robots must cooperate in…– Strategy acquisition– Real-time reasoning– Multi-agent collaboration– Competition against another
team of robots
RoboCup is an international research effort to promote autonomous robots.

• Each robot has…– Pentium 233MHz– Linux OS– Video camera and
frame grabber– Sensor System– Kicker
![Page 30: 569637 634222725772371250](https://reader033.vdocument.in/reader033/viewer/2022060116/5583a702d8b42a5b318b55a2/html5/thumbnails/30.jpg)
How to the robots make decisions?
• Control is based on a set of behaviors• Each behavior has a set of preconditions that either…
– Must be satisfied– Are desired
• A behavior is selected when all of the “musts” become true
• A behavior is selected from several behaviors based on how many desired conditions are true
![Page 31: 569637 634222725772371250](https://reader033.vdocument.in/reader033/viewer/2022060116/5583a702d8b42a5b318b55a2/html5/thumbnails/31.jpg)
Applications of AI and Robotics
• Industrial Automation• Services for the Disabled• Vision Systems• Planetary Exploration• Mine Site Clearing• Law Enforcement• And Many Others…

The Humanoid COG• MIT’s finest• Broken down COG is just a bunch
of sensors and actuators• Except for legs and a flexible
spine, COG has all the major degrees of freedom of the human upper body
• Sight exists through video cameras
• Hearing, touch, hand motion, and speech are being added soon

Got idea about the “ALL ROUNDER OF THE FUTURE GENERATION”??????
![Page 38: 569637 634222725772371250](https://reader033.vdocument.in/reader033/viewer/2022060116/5583a702d8b42a5b318b55a2/html5/thumbnails/38.jpg)
Why build a human-like robot?
• Our bodies are critical to the representations that we use for internal thought and language
• If a robot is looks like a human then it will be natural for humans to interact with it in a human-like way
• To develop similar task constraints
CONCLUSION
