Robotics or the term Robot can be defined as a reprogram able, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks.
Another definition for a robot is a device that can move and react to sensory input. Robotics is one branch of Artificial Intelligence.
Robots are now widely used in factories to perform high-precision jobs such as welding and riveting. They are also used in special situations that would be dangerous for humans; for example in cleaning toxic wastes or defusing bombs.
Although great advances have been made in the field of robotics during the last decade, robots are still not useful in everyday life, as they are too clumsy to perform ordinary household chores.
Robota is the Czech word for forced labors.
Writer Isaac Asimov introduced the term robotics. He presented three laws for robotics:
- A robot may not injure a human being, or, though inaction, allow a human being to come to harm.
- A robot must obey the orders given to it by human beings except where such orders would conflict
  with the first law.
- A robot must protect its own existence as long as this does not conflict with the first and second
Examples are new lightweight robots and advanced vehicle systems with active components.
Such projects integrate the core skills in dynamic system modeling and simulation, design of robust control algorithms and multibody formalisms, development of highly integrated robot sensors and actuators and remote control of semi-autonomous systems.

        On the other hand, Bioengineering is a fast-growing part of the engineering profession and mechanical engineers are very involved in it.
Bioengineering applies engineering principles and methods to medicine, biology, and behavior. It has made enormous contributions to the advancement of health care in the United States and around world.
Bioengineering is behind some of the latest advances in the medical field. Some of these advances include combination heart-lung transplants, hip joint replacements, artificial hearts, and prosthetic devices.
