| Absolute Encoder | An optical encoder that gives an exact position even in the event of a power failure. |
| Accuracy | The degree of closeness of measurements of a quantity to the actual (or accepted) value. |
| Debug | The process of detecting and eliminating a device’s malfunctions. |
| End Effector | A tool or gripper attached to the end of a robotic arm. |
| Handshaking | Handshaking is a form of communication where a signal is sent from a device to another similar or dissimilar device(s). |
| Home | A reference point from which all of the robot’s movements are measured. |
| Incremental Encoder | An optical encoder that gives incremental position from a known position. |
| Input | The data supplied to the computer for processing. |
| Joint | A single degree of arm rotation or translation. |
| Kinematics | The spatial arrangement of the axes of movement in relation to one another. |
| Loop | The repeated execution of a series of instructions for a variable number of times. |
| Microcontroller | A microprocessor used for precise process control in data handling, communication, or manufacturing. |
| Optoisolators | Optical Isolators use a small IR LED connected to the input side of the circuit. |
| Output | Information transferred from the robot controller through the module to control external devices. |
| Payload | The maximum weight that can be carried by a robot in normal and continuous operation. |
| Precision | The degree to which repeated measurements show the same result. It is interchangeable with the key term repeatability. |
| Relay | A relay electrically operated switch that uses a magnet and a reed switch to complete a circuit. |
| Reliability | The probability that a component part, equipment, or system will satisfactorily perform its intended task. |
| Repeatability | The degree to which repeated measurements show the same result. It is interchangeable with the key term precision. |
| Robotic Control System | Provides a logical sequence for a robot to follow. |
| Roll | Circular motion at an axis; a rotation about the link axis of a robot’s wrist. |
| Servo Motor | Any motor that is modified to give feedback concerning the motor's speed, direction of rotation, and number of revolutions. |
| Stepper Motor | A motor that rotates a predefined angle with every electrical impulse. |
| Subroutine | A small program inside a large one. Used when the same series of commands are repeated multiple times. |
| Syntax | The rules governing the structure of statements used in a program. |
| Work Envelope | The volume of space defined by the maximum reach of a robot arm in three dimensions. |
