Class Vocabulary
autotune		A feature in some motor control devices that automatically adjusts the control system at start-up.
blockout		An energy-isolation procedure that physically prevents the flow or movement of energy. Blockout is often a failsafe backup to lockout/tagout.
centralized lubrication system		An automated lubricant delivery method that lubricates multiple robot parts at once.
control system		A manual or automatic mechanism used to manage dynamic processes by adjusting or maintaining physical variables such as velocity or positioning.
downtime		Unproductive blocks of time during which robot operations cease, often due to mechanical problems.
drip feed		A type of lubricant delivery system that includes a small reservoir of lubricant connected to pipes that distribute the lubricant to robot parts.
friction		The resistance to relative motion between surfaces. Friction is caused by contact between surface asperities.
gravity lubrication system		A type of lubricant delivery system that uses individual lubricant reservoirs from which lubricant is distributed to robot parts. This system is often used with drip feeds or wick feeds.
hand-operated gun		A device used to apply lubricant manually to robots.
lockout/tagout		A method of protecting employees from accidental startup through proper locking and labeling of robots that are undergoing maintenance.
lubricant		A substance used to reduce friction between two surfaces in relative motion. Oil and grease are common industrial lubricants.
maintenance		The necessary and basic support and repair of machines. Robot maintenance includes tasks such as lubricating, adjusting, and replacement of parts.
oil mist system		A lubricant delivery method that pipes oil throughout the robot to desired locations and dispenses the oil with a spray nozzle. Oil mist systems cool and lubricate many robot parts at once.
overlubrication		The process of applying too much lubricant to a robot component. Overlubrication can lead to robot malfunction.
preventive maintenance		Maintenance performed while a robot is in working order to keep it from breaking down.
relative motion		A change in position of one object in relation to another object. Contact between two objects in relative motion causes friction.
tuning		A system of adjusting the controller's response to error by adjusting values in the PID algorithm.
wick feed		A type of lubricant delivery system that includes a small reservoir of lubricant that distributes the lubricant to robot parts through a strip of absorbent material, which also filters the lubricant.
