from Begin Robotics - University of Reading


 * Controller - A device which forms part of a control system – often taking the error between the desired state and the actual state and generating data used to affect an actuator.
 * Force Feedback - A method whereby a sensor conveys to the user the force felt when touching an object.
 * Fuzzy Logic - A form of logic which deals with approximate values, as opposed to logic signals which are true or false only.


 * Error - In a control system, the difference between the desired state and the actual state.
 * Excitatory - connection between neurons which enhances action (as used in Neural Networks and Braitenberg vehicles).
 * Feedback - The process of returning information about the output of a system.
 * Feedback Loop - A circular path along which information is passed.


 * Assembly robot - A robot used typically in a production line manufacturing (e.g. cars).
 * Autonomous robot - A robot which works on its own, as opposed to being controlled by a human.


 * What's the problem?**
 * **Ask** -

 * That's engineering**
 * Proportional Control - A strategy where the controller outputs a value which is the error multiplied by a constant (is proportional to the error).
 * Touch sensor - A sensor which measures some aspect of the physical contact with an object.
 * Vision Sensor - A device which gives a visual representation of something – typically from a camera.
 * Integral control - A method used in Feedback Control where the output of the controller depends on its input (typically the error) and previous values of its output.
 * Gain - The size of the output of an element divided by its input – in a Proportional Controller, its output is the error * the gain.
