industrial robotics introduction

1. Introduction of Industrial Robotics Rajesh papatla Assistant professor Department of mechanical engineering Ramachandra college of Engineering., Eluru.

2. contd…,

3. What is industrial Robot According to Robotic Institute of America (RIA) “A robot is a reprogrammable, multi functional manipulator designed to move materials, parts, tools or specialized devices through variable programmed motions for the performance of the variety of the tasks”

4. Components of robot

5. Types of Robots

6. Comparison chart

7. U se robots! Perform 4A tasks in 4D environments 4A: Automation Augmentation Assistance Autonomous 4D: Dangerous Dirty Dull Difficult

8. How to select a robot Degrees of Freedom and Workspace Power source Based on controlled system b ased on arm configuration Minimum to maximum distance moved Accuracy & repeatability Based on wrist configuration Type of material to be handled Torque of the joints

9. History of robotics

10. Unimate Revolutionizing manufacturing the world over, the Unimate was the very first industrial robot . Conceived from a design for a mechanical arm patented in 1954 (granted in 1961) by American inventor George Devol, the Unimate was developed as a result of the foresight and business acumen of Joseph Engelberger - the Father of Robotics .

11. WABOT-1 (1970~1973) The WABOT-1 was the first fun-scale anthropomorphic robot developed in the world. It consisted of a limb-control system, a vision system and a conversation system. The WABOT-1 was able to communicate-with a person in Japanese and to measure distances and directions to the objects using external receptors, artificial ears and eyes, and an artificial mouth. The WABOT-1 walked with his lower limbs and was able to grip and transport objects with hands that used tactile-sensors.

12. Third generation robots (AIBO)

13. ROBONUT II

14. Robots of Today

15. Laws of robotics 1st law: A robot may not injure a human being , or through in action, allow one to come to harm.

16. contd.., 2nd law : robot must obey the orders given to it by the human beings except where such orders would conflict with the 1st law.

17. contd…, 3rd law A robot must protect its own existence as long as such protection does not conflict the 1st and 2nd laws

18. Automation Technology that is concerned with the use of mechanical, electronic and computer based systems in the operation and control of production It usually refers a combination of 1. Computerization of information processing in manufacturing 2. Automation of manufacturing systems in the factory.

19. contd…, Ex:1. Automatic machine tools to process the parts 2. Automatic Assembly machines 3. Industrial robots 4. Automatic material handling and storage system 5. Automatic inspection system 6. Process control system etc.,

20. Typical automation cycle

21. Classification of automation 1. Fixed automation 2. Programmable automation. 3. Flexible automation

22. contd..,

23. Basic elements of automation system Consist of three basic elements : The actuator ( which does work) controlled by the controller The actuator is a automated process may in fact be several actuators , each of which provides an output that drives another in the series of actuators .

24. contd…, 2. The controller ( which ‘tells’ to the actuator to do the work ) A controlled system either may be a simple digital system or an analog system . Digital and analog controllers are available “of the shelf”so that system can be constructed inexpensive and with little specialized knowledge is required

25. contd…, 3. Sensor ( which provides to feed back to the controller so that it knows the actuators are doing the work Obviously , controlled automation requires devices to sense system output . Sensor also can be used so that a controller can detect and responded to changing conditions in its working environment

26. Reasons for automation To increase labour productivity To reduce labour cost To improve worker safety To improve product quality To migrate the effect of labour shortages To reduced MFG Lead time To accomplish process that cannot be done manually

27. Classification of Robots JIRA (Japanese Industrial Robot Association) Class1: Manual-Handling Device Class2: Fixed Sequence Robot Class3: Variable Sequence Robot Class4: Playback Robot Class5: Numerical Control Robot Class6: Intelligent Robot

28. Present and future applications Current robotics applications Welding Spray painting Grinding Other applications involving a rotary tool i.e. drilling holes, polishing etc. Parts handling/transfer Assembly operations Parts sorting Parts inspection

29. Future robotics applications Hazardous and inaccessible non manufacturing environments Construction trades Underground coal mining Military applications fire fighting Undersea robots Robots in space

30. Service industry and similar applications Teaching robots Retail robots Fast food restaurants Bank tallers Garbage collections and waste disposal operations Cargo handling, Loading, and Distribution Operations Security guards Medical care and hospit al duties Agricultural robots Household robot
