Robot

In practical usage, a robot is an autonomous or semi-autonomous device which performs its tasks either by direct human control, partial control with human supervision, or completely autonomously. Robots are typically used to do tasks that are too dull, dirty, or dangerous for humans. Industrial robots used in manufacturing lines used to be the most common form of robots, but that has recently been replaced by consumer robots cleaning floors and mowing lawns. Other applications include toxic waste cleanup, underwater and space exploration, surgery, mining, search and rescue, and mine finding. Robots are also finding their way into entertainment and home health care.

Robotics

According to the American Heritage Dictionary, robotics is the science or study of the technology associated with the design, fabrication, theory, and application of robots.

Robotics requires a working knowledge of electronics, and depending on the size of the project, pneumatics, hydraulics, and microcontrollers / programmable logic controllers. A standard process while creating a robot will begin with evaluating the best method of creating motion, usually being electric actuators (like motors and solenoids), or to a lesser extent, pneumatics or hydraulics.

After the basic construction has been completed, sensors and other inputs and outputs throughout the robot are connected to a decision-making device, usually an electronic circuit consisting of a microcontroller or similar device. This circuit evaluates the input signals, calculates what the appropriate response is, and sends appropriate signals out to the actuators to cause a reaction. The end result should be the ability to control the robot with the push of a button.
