Definition of Robotics Engineering

Robotics engineering is the process of designing, building, and programming robots that can perform tasks autonomously or under human supervision. It involves the application of various engineering principles such as mechanical, electrical, and computer engineering. Robotics engineers design robots for different applications, such as manufacturing, healthcare, space exploration, and military operations.

Brief History of Robotics Engineering

The origins of robotics engineering can be traced back to ancient times, where Greek mythology tells of the god Hephaestus creating mechanical servants to assist him in his work. However, the modern era of robotics engineering began in the 1950s when researchers started experimenting with building machines that could perform simple tasks. The first industrial robot, Unimate, was developed by George Devol and Joe Engelberger in 1961. Since then, robotics engineering has evolved significantly, and robots are now used in various applications.
