Category of the Course:

Professional Core Courses

Prerequisite:

A  basic  understanding  of  mechanical  and  electrical  engineering  principles  is essential for this course. Students should be familiar with fundamental mechanisms,  engineering  drawings,  simple  circuits,  motors,  and  sensors.  Basic computer skills and prior exposure to 2D drafting, preferably using AutoCAD, will support effective learning. Knowledge of simple programming logic in languages such as C or Python is beneficial but not mandatory. A foundation in mathematics, especially  geometry and coordinate systems, is helpful for robot motion and 3D modelling  tasks.  Above  all,  learners  should  possess  curiosity  and  interest  in robotics,  automation,  and  digital  design  to  fully benefit from  the  practical activities.

The field of robotics, automation, and 3D modelling is rapidly advancing and has become  an  essential  part  of  modern  engineering  and  manufacturing  industries. This  practical  course  is  designed  to  equip  students  with  fundamental  skills  and hands-on experience required to work effectively with robotic systems and digital design  tools.  The  course  introduces  students  to  the  basics  of  robotics,  including robot types, mechanisms, degrees of freedom, and industrial applications. Emphasis  is  placed  on  safety  practices,  understanding  robot  components,  and exploring the role of sensors and actuators in real-world automation systems.

Students  learn  to  program  robots  using  point-to-point  and  interpolated  motions, enabling  them  to  plan  paths,  optimize  cycle  times,  and  troubleshoot  common errors, particularly in pick-and-place applications. In parallel, the course provides comprehensive  training  in  3D  solid  modelling  using  AutoCAD  and  parametric software. Through part modelling, assembly creation, and documentation, learners gain essential competencies in digital design and product development.

The inclusion of a mini-project encourages creativity and practical integration of concepts,  while industrial  visits  offer  exposure  to  real  automation  environments. Overall,  this  course  aims  to  develop  technically  skilled  graduates  capable  of contributing to robotics, automation, and digital manufacturing sectors.

3. Encourage participation in structured competitions These events often require teams to build and program robots to solve a specific, themed challenge, using a mix of design, building, and programming skills.

## Any Other:

Other  than  the  laboratory  learning,  following  are  the  suggested  student-related  co-curricular  activities which  can  be  undertaken  to  accelerate  the  attainment  of  the  various  outcomes  in  this  course:  Students should perform following activities in groups and prepare reports of about 5 pages for each activity. They should also collect/record physical evidences for their(student's) portfolio which may be useful for their placement interviews.

-  Massive open online courses (MOOCs) may be used to teach various topics/subtopics.
-  Guide students on addressing the issues on environment and sustainability using the knowledge of this course
-  Guide students for keeping the drawings in digital form and reduce use of paper.
