Int. Std. Org. (ISO) Definition • Robot An automatically controlled, re-programmable, multi-purpose manipulative machine, with or without locomotion, for use in industrial automation applications • Other definitions: Rob. Soc. of Japan, etc. • Common temrs temrs: Re-programmable, Multipurpose
Laws of Robotics • By Issac Asimov (1940s) 1. A robot may not injure a human being or, though inaction, allow a human being to come to harm. 2. A robot must obey the orders given by human beings, except when such orders would conflict with the first law. 3. A robot must protect its own existence, as long as such protection does not conflict with the first or second law.

Reasons for Poor Utilization • Mainly due to U N E M P L O Y M E N T
[Japan with 3 50 000 robots in 1992 had < unemp oymen • Other reasons
More Reasons • R&D Supports: By Govt. only • Companies involved: Almost nil • Advanced Advanced Research Absorption: Poor • Questions: Should We Use Robots?
Yes
– Lack of proper perspective – Cheap labour – Non-availability – High import cost/High investment

Do We Need Robots? If yes, how?
Yes (modified way) Let’s see

Where and How?
Robotics in Our Countries • To Overcome `Robotics ` vs. Unemployment’ • Do we like to o
–
– weld two parts for 8H/day for several years? [Monotonous]
• Robot = Machine [Robot
≠
Human]
• How?
– In hazardous environment (Chemical, Steel, Nuclear, … plants) – High precision applications – Export oriented products
When to Use a Robot?
– Indigenous design – Develop as required – Make awareness – Think it as a machine
RoC-BEE RoCConcept
Thumb Rules: • Is task Dirt
• Where?
Dull Dan erous Difficult?
• Will a human be be jobless?
• Robotics Contest Contest--Based Education in Engineering (RoC(RoC-BEE)
• Is a human willing to to do aa job?
• Demonstration through Robocon
• Is robot usage economic? economic?

Robocon Activity in Brief • Requires about 1515-20 students – Mechanical, Electrical, …
• 7-8 months re arations • Min. Rs. 11-2 lakhs (US$2(US$2-4K) • Can be integrated with course course work work • CGPA increased
Conclusions • Robotics is explained
Thank You
• Several advanced robots are shown • Robocons are emphasized
