A position sensor is a sensor that detects an object's position. A position sensor may indicate the absolute position of the object (its location) or its relative position (displacement) in terms of linear travel, rotational angle or three-dimensional space. Common types of position sensors include the following: Capacitive displacement sensor
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. [1] There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle ...
Software for industrial robots consists of data objects and lists of instructions, known as program flow (list of instructions). For example, Go to Jig1 It is an instruction to the robot to go to positional data named Jig1. Of course, programs can also contain implicit data for example Tell axis 1 move 30 degrees.
Absolute encoders can determine their position at power-on but are more complicated and expensive. Incremental encoders are simpler, cheaper, and work at faster speeds. Incremental systems, like stepper motors, often combine their inherent ability to measure intervals of rotation with a simple zero-position sensor to set their position at start-up.
The windmill fantail is an earlier example of automatic control, but since it does not have an amplifier or gain, it is not usually considered a servomechanism. The first feedback position control device was the ship steering engine, used to position the rudder of large ships based on the position of the ship's wheel. John McFarlane Gray was a ...
Programmable in StickOS BASIC, and C or assembly language using Flexisframework or CodeWarrior with a step-by-step debugger. The Firebird32 is also available in a special model based on the 8-bit MC9S08JM60.

ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.
Many incremental encoders have an additional output signal, typically designated index [2] or Z, [3] which indicates the encoder is located at a particular reference position. Also, some encoders provide a status output (typically designated alarm) [4] that indicates internal fault conditions such as a bearing failure or sensor malfunction.
