robot

A robot is an electro-mechanical device that can perform autonomous or preprogrammed tasks. A robot may act under the direct control of a human (eg. the robotic arm of the space shuttle) or autonomously under the control of a programmed computer. Robots may be used to perform tasks that are too dangerous or difficult for humans to implement directly (e.g. nuclear waste clean up) or may be used to automate repetitive tasks that can be performed with more precision by a robot than by the employment of a human (e.g. automobile production.) Robot can also be used to describe an intelligent mechanical device in the form of a human, a humanoid robot. This form of robot (commonly referred to as an android) is common in science fiction stories. However, such robots have yet to become commonplace in reality, especially with the difficulties (and expenses) involved in making a bipedal machine balance itself or move in human-like ways without losing balance (see Current Developments below). Internet bots are named after the word robot because they perform mundane, repetitive tasks.
