ROBOTICS: ROBOTICS Umapathysivam .T Robotics: Definition: Robotics: Definition Robotics is the branch of technology that deals with the design, construction, operation, structural disposition, manufacture and application of robots. The word robotics was derived from the word robot , which was introduced to the public by Czech writer Karel Čapek in his play R.U.R. ( Rossum's Universal Robots) , which premiered in 1921. Karel Čapek What is a robot?: What is a robot? “A re-programmable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks.” History of Robotics: History of Robotics 1940 – Isaac Asimov produces a series of short stories about robots starting with “A Strange Playfellow” (later renamed “Robbie”) for Super Science Stories magazine. The story is about a robot bound to protect a child. It is later compiled into the volume, “I, Robot” in 1950. 1941 - Science fiction writer Isaac Asimov first used the word "robotics" to describe the technology of robots and predicted the rise of a powerful robot industry. Slide 5: 1942 - Asimov wrote "Runaround" , a story about robots which contained the "Three Laws of Robotics": A robot may not injure a human, or, through inaction, allow a human being to come to harm. A robot must obey the orders it by human beings except where such orders would conflict with the First Law. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. He later adds the “ Zeroth Law”. A robot may not injure humanity, or, through inaction, allow humanity to come to harm. Slide 6: 1948 - "Cybernetics ", an influence on artificial intelligence research was published by Norbert Wiener . 1956 - George Devol and Joseph Engelberger formed the world's first robot company. Slide 7: 1997 –Pathfinder lands on Mars. 1997 – The first node of the ISS is placed in orbit using a robotic arm. 1998 – Tiger Electronics introduces Furby . It can react to its environment and communicate using over 800 phrases. 2004 – The Mars Exploration Rovers Spirit and Opportunity land on Mars and prove that Mars was once covered with water. Slide 8: 2004 – I, Robot, new version of robots trying to take over the world. 2005 - Honda debuts new Asimo robot that can complete office tasks. Roles and jobs of robots: Roles and jobs of robots Computer Assisted Manufacturing Military Medical Space Exploration Personal Types of Robots: Types of Robots Pick and place -Moves items between points Continuous path control -Moves along a programmable path Sensory -Employs sensors for feedback Pick & Place: Pick & Place Moves items from one point to another Does not need to follow a specific path between points Continuous path control: Continuous path control Moves along a specific path Uses include welding, cutting, machining parts. Sensory : Sensory Uses sensors for feedback. Closed-loop robots use sensors in conjunction with actuators to gain higher accuracy – servo motors. General components: General components General Components of an industrial Robot:- Manipulator The part of the robot that performs the task General components: General components Controller Brain or computer center which coordinates the robot’s movements Power supply Hydraulic Pneumatic Electric Vacuum Often a combination; the end-effectors mostly pneumatic Vehicle Used to move the robot on a track, free wheels, treads, or some type of legs/feet Tasks: Tasks Tasks which are: Dangerous Space exploration chemical spill cleanup disarming bombs disaster cleanup Boring and/or repetitive Welding car frames part pick and place manufacturing parts. High precision or high speed Electronics testing Surgery precision machine Applications of Robots: Applications of Robots Space Exploration Two important devices exist which are proven space robots Remotely Operated Vehicle (ROV) Remote Manipulator System (RMS ) Slide 18: This picture shows a Historic Space Handshake between Shuttle and Space Station Robots - Image Courtesy of CSA Slide 19: Robotic Wheelchair can facilitate patient locomotion Manufacturing: Manufacturing Probably 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 Agriculture: Agriculture Robots 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 ’. RoboCup: 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. Slide 25: Each robot has… Pentium 233MHz Linux OS Video camera and frame grabber Sensor System Kicker CONCLUSION: Why build a human-like robot? CONCLUSION 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 Slide 27: THANK YOU
