Robotics: Basics and Selected Advanced Concepts

By Prof. Ashitava Ghosal   |   IISc Bangalore
Learners enrolled: 500
This course starts with an introduction to robotics, the key elements and constituents of a robot and science and technology in robots. It provides a unified treatment for the modelling and analysis of serial, parallel, and hybrid manipulators using the key concept of Denavit-Hartenberg parameters, solution of the direct and inverse kinematics of serial and parallel robots and the associated concepts of workspace and mobility are presented. The concept of velocity of the links of the robots and the Jacobian matrix is developed and the associated concepts of singularities in robots are discussed in depth. The equations of motion are derived using the Lagrangian formulation and their solutions using numerical methods are presented. To fully understand control of robots, basic concepts in linear control is introduced using the example of control of a single link of a robot and then the more advanced concept of model-based control is discussed. The course also introduces advanced topics in robotics such as modelling and analysis of wheeled mobile robots, deployable structures and cable driven and pneumatically actuated small/micro robots. The course draws upon a great deal on experiments and hardware developed by research students at IISc and software simulations and hardware experiments are suggested for the course students to do on their own to complement the material taught in the course.

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).
Date and Time of Exams: 23 April 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IISc Bangalore.It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.
