the groundwork for industrial robots.
The earliest documented industrial robot dates
back to 1937, when Griffith Taylor
engineered a crane-like device capable of autonomously stacking wooden blocks
based on predefined patterns.
In 1954, George
Devol, often hailed as the ‘Grandfather of Robotics,’ secured the first
patent for an industrial robot.
By the 1990s, remote-controlled robots
revolutionized industries by introducing synchronized operations.
Laws of Robotics
Isaac Asimov formulated the "Three
Laws of Robotics," which were articulated within his fictional works to
establish ethical guidelines for interactions between humans and robots:
1. The First Law states
that a robot must not harm a human being or, through inaction, allow a human
being to come to harm.
2. The Second Law
mandates that a robot must obey orders given by humans, except where such
orders conflict with the First Law.
3. The Third Law requires
a robot to protect its own existence as long as such protection does not
conflict with the First or Second Law.
Components of a Robot
A robot typically consists of several key
components that work together to enable its functionality. These components can
vary depending on the type and purpose of the robot, but generally include:
