Mechanical is a branch of engineering which focuses on designing a component, machine, process, or system with the fundamental knowledge of force, energy, and motion. Mechanical Engineers are the group of people who design a car's engine, the air conditioner's compressor, or the maneuver arm's mechanism. Mechatronics Engineering is a specialized combination of Mechanical and Electronics Engineering. It is a combination of principles in mechanics, electronics, and computing. Mechatronics is a branch of engineering that aims to improve technical systems with added artificial intelligence like autonomous vehicles, auto-braking systems, and even autofocus cameras. In short, Mechatronics Engineer is a profession to make any existing systems smarter.
