This document discusses trends in robotics. It defines a robot as a computer programmable machine that can be guided to carry out complex actions automatically. Robots are used across many fields like factories, services, healthcare, military and space exploration. They are capable of grasping objects, making decisions autonomously, and performing repetitive or dangerous tasks for humans. Robots also help with impairments, collaborate with humans, and work in unstructured environments. The document outlines different classes and types of robots used for industrial, service, medical, military and space purposes. It concludes by noting robots serve as innovative work tools but could also threaten humanity if not developed responsibly.
