Robotics

MCA course is specially designed for computer graduates and robotics is a part of mechanical , there is no course named as MCA in robotics, you can pursue BE Btech in robotics

USA and Germany are best for the courses you hv mentioned. In india, you may look into IITs for the same.

Robotics and Automation deals with the use of robots at different levels in the manufacturing, assembly or inventory management fields to ease the material handling by personnel. It leads to high cost saving by the companies with high degree of accuracy, safety and low accidents, defectives. So it involves the study of robot components, parts, programming, automation layout concepts and the like.

Robotic is a multi dicipilanary branch where both concepts and understanding of Mechanical, embedded Electronics and programming is required. Generally students do either BTech Mechanical or Electronics and then do MS/ MTech in Robotic Engineering.

There is no engineering course that has more practical subjects and less theoretical, also both practical and theoretical knowledge plays important role during placements. But if you are good at analysis and calculations, you can choose mechanical engineering because it has more subjects that has numeric problems.

if you want to become a valuable engineer than do that from any iit or bits.

Robotics is the branch of mechanical engineering, electrical engineering and computer science that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing. Robotics engineers are employed in design, development and production of industrial robots. Robotics is mankind step towards automation and its has good future with increased utilization of robots in manufacturing and to undertake tasks which are difficult for human being.

it is regarding to robotic development few IIT and NIT offer it.
