FINAL EXAM ROBOTICS QUESTIONS
AND ANSWERS
Absolute optical encoder - Correct Answers -An encoder with enough emitters and
receivers to give each position of the encoder its own unique binary address
Accumulators - Correct Answers -Devices used to store hydraulic pressure and then
release it back into the system as needed
Alphanumerical format - Correct Answers -Information in the form of letters and
numbers
Analog - Correct Answers -Data with a range of values based on the sensor or device
Analog signal - Correct Answers -A signal with a range of voltage or amperage that
correlates to a set scale used to express changing values in the sensors and output
devices
And - Correct Answers -A logic function that requires two or more separate events or
data states to occur before the output of the function occurs
Arc flash - Correct Answers -An electrical catastrophe where two main legs of a system
short out and draw enough amperage to create an electrical explosion complete with
pressure waves, shrapnel, vaporized metal, and enough heat to instantly cause second-
and third-degree burns
Arcs - Correct Answers -A portion of a circle
Automatic mode - Correct Answers -A condition where the robot runs the program
without continued operator input based on the operating parameters of the program
Binary - Correct Answers -A base 2 number system with 0 or 1 for each position
Binary address - Correct Answers -A unique set of 1s and 0s that the controller can
understand and use
Bit - Correct Answers -The smallest unit data can be broken into
, Brainstorming - Correct Answers -A group of people getting together to come up with a
variety of ideas about a topic or problem
Calibration - Correct Answers -A specified process that ensures that a precision system
performs properly and provides for any adjustments needed
Call program/subroutine - Correct Answers -A command that calls up subroutines or
other programs to help reduce the lines of code in a program
Capacitive proximity switch - Correct Answers -A switch that generates an electrostatic
field; working on the same principle as capacitors, it uses the item sensed to complete
the capacitive circuit as well as sense materials at various distances
Circular - Correct Answers -A motion described by no fewer than three points to create
arcs or circles
Closed-loop system - Correct Answers -A system that sends out the control pulse to
initiate movement and then receives a return signal that confirms movement, often
including the direction, speed, and distance moved
Common connection - Correct Answers -Connections used to provide power or signal to
contacts controlled by switches or relays
Continuity - Correct Answers -Unbroken electrical connection between two points
Continuous mode - Correct Answers -A condition where the program runs as it would
normally, provided that the proper inputs—such as the dead man switch and manual
button or similar—are maintained
Coordinate systems - Correct Answers -Another term for frames
Crash - Correct Answers -The robots unexpected contact with something in the work
envelope
Critical alarms - Correct Answers -Error conditions that prevent the machine from
running until corrected
Cycle time - Correct Answers -The time it takes to complete the program one time from
start to finish
Decimal numbers - Correct Answers -The base 10 numbering system that most of us
are familiar with
Digital - Correct Answers -Data with a value of 0 or 1
Digital signal - Correct Answers -A signal that has exactly two states, 1 or 0
