This document provides an introduction to robotics. It defines a robot as a mechanical arm designed to perform repeated tasks through variable programming. Robots move objects and tools using pre-programmed motions and points to complete assigned tasks. The document discusses what robots look like, why they are used, and how they have developed over time. It also mentions how robotics draws from fields like mechanical engineering, mathematics, control theory, electrical engineering, and computer science to design robots and allow them to perform tasks through programming.
