I am selected for the final round of an international science competition named iken Scientifica. In this final round, I have to choose any two topics among these 5 topics- Industrial Mechanics / Energy Conservation / Robotics / CAM mechanism / Hydraulics and then I've to make a model on them.
So I was just wondering that what is industrial mechanics and how can I make a model based on it? Please explain about industrial mechanics as much as you can.
And please give some short explanations on the rest 4 topics too.
Thank You...!!!
