Collaborative Robots (COBOTS): Theory and Practice

By Prof. Arun Dayal Udai   |   IIT-ISM Dhanbad
Learners enrolled: 590   |  Exam registration: 7
ABOUT THE COURSE:
The content of the course is designed as a basic undergraduate/postgraduate course where the engineering students of the first year should be able to pick up well. Fundamentals of traditional industrial serial robots is included for students who have not attended any formal robotics course. Each module comprises of theoretical lectures that lay the foundation, code demonstrations, and home-assignments for enhance the penetration of the core syllabus and would finally end with an end-of- course exam. In addition to formal lectures, the course would also include lab. demonstrations to further explain the concepts that are taught through the theories. This will help students to have enough exposure to pursue the subject further as professionals in the industry or as students of higher education in top universities in India or abroad.

INTENDED AUDIENCE: University Students and Industrial Practitioners

PREREQUISITES: UG Level: Mathematics (Linear Algebra, Calculus) and Basic Engineering Mechanics

INDUSTRY SUPPORT: INDUSTRIES: Automobile, Electrical and Electronics, Plastics and Chemicals, Food and Beverage, Educational/Research, etc.

Prof. Arun Dayal Udai

IIT-ISM Dhanbad
Prof. Arun Dayal Udai is a faculty in the Department of Mechanical Engineering, IIT (ISM) Dhanbad. He has over 15 years of experience in teaching Mechatronics, CAD, Robotics and Automation. He did his Ph.D. in 2016 from IIT Delhi with a specialization in Force Control of Industrial Robots. He did his Master's in Mechanical Engineering (Design) from BIT Mesra, Ranchi in 2006 where he worked on Biped Robots. He completed his UG in Marine Engineering from MERI, Kolkata in 1999 and worked with Anglo-Eastern Ship Management, Hong Kong for four years as Mercantile Marine Engineer. He has sailed across the globe on-board ships to different countries and acquired expertise in various areas of mechanical engineering. He has published in various peer-reviewed journals, conferences and has co-authored the textbooks on Computer Graphics published by McGraw Hill, New Delhi in 2008, and on Vision Based Identification and Force Control of Industrial Robots, published by Springer Verlag, Singapore, in 2022. Currently, he is also a Founder and Director of his company ADUZA Robotics and Automation Pvt. Ltd. where he is making his robots for academics and research purposes and provides consultancy to various industries in robotics and automation. He is handling projects that worth more than 3.5 Crores on Robotics which are funded by defense, Govt. of India, and different industries. His existing NPTEL course Industrial Robotics: Theories for Implementation which was floated in Monsoon 20203 has gained quite popularity among UG/PG and Ph.D. students of Industrial Robotics.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
