degrees of freedom The available ways a component can move in three-dimensional space. Robots typically have 3 to 6 degrees of freedom.
dross A type of scum formed by oxidation at the surface of molten metals.
end-effector The end component of a robotic arm that is shaped like a hand or like a specialized tool. Also known as end-of-arm tool (EOAT).
end-of-arm tool The end component of a robotic arm that is shaped like a hand or like a specialized tool. Also known as an end-effector.
feeler A sensor on a robot that responds to touch or pressure.
fork vehicle A type of AGV that can lift and lower materials. Forks are available in different styles other than the standard dual fork.
gripper A hand-shaped end-effector designed for seizing and holding.
industrial robot A programmable mechanical device that is used in place of a person to perform dangerous or repetitive tasks with a high degree of accuracy.
input/output module The jack where an input/output device is physically connected to a robot. Inputs and outputs allow the robot to interact with its environment.
integrated circuit A miniaturized electronic circuit. The development of integrated circuits helped to improve the performance of industrial robots.
intelligence The ability to learn, reason, and solve problems.
joint The location at which two or more parts of a robotic arm make contact. Joints allow parts to move in different directions.
lead-through programming A programming method in which a robot is placed in "teach mode" while the trainer uses a remote teach pendant to manipulate the robot through the different steps of the job. Lead-through programming is the most common programming method.
linear joint A joint that moves in a straight line across one axis. Also known as a prismatic joint.
linear movement Movement in a straight line across one axis.
