Limit switches communicate information through output ports.
false
Common I/O ports include interface and image analysis.
false
During ______, an analog-to-digital converter changes the analog signal
of an image into an equivalent digital signal.
image preprocessing
The functions that take place during image processing are preprocessing,
interpretation, analysis, and
acquisition
Although this data transmission method is faster, it is generally
considered too costly to use over long distances.
parallel
This port is commonly used for serial transmission of data between a
robot and a computer.
RS-232C
Two computers can communicate with each other over telephone circuits via
ethernet
WRONG
ports connected to modems.
The common point at which two or more systems communicate is a(n)
interface
Identify and explain the four functions that take place during image
processing.
There are four functions that take place during image processing. These
functions are image acquisition, image preprocessing, image analysis, and
image interpretation. During acquisition a work piece is illuminated to
enhance it's surface features, and an image digitally is created. The
image is captured with a digital camera. During preprocessing the signal
is converted from an analog signal to an equivalent digital signal with
and analog-to-digital converter. This transforms the image into
pixels. The values of the pixels are stored for later
interpretation. Image analysis is a function of machine
vision. Analysis is performed by software. The software identifies,
measures, and analyses features of the image. Interpretation is the
process during which the scanned image is compared to a model image, or
it's corresponding data. A decision is made about whether the image
matches the model and the decision is sent to the robot to enable the
robot to make decisions about tasks that it needs to do.
Most manufacturers of robotic equipment do not provide troubleshooting
manuals to aid in repairs.
false
Scrap is a manufactured part that is reconditioned and put back into
service.
false
Most system problems are ______ failures.
component
Repairs to complex robotic systems are commonly performed on the
_______________ .
subassemblies
______ is key to preventative maintenance.
Documentation
An oscilloscope or multimeter and _______________ is most commonly used
to isolate a system problem.
voltmeter
A ______ solder should be used for all electronic circuit work.
resin-core
Preventative maintenance programs place a great deal of responsibility on
the ______.
operator
During the initial observation of equipment to be serviced, what should
you look for?
During the initial observation of equipment to be serviced, there are a
number of things that you should look for. These include burned parts,
broken parts, broken wires, poor wire connections, smoke, and heat
damage. You should also look for oil, air, or water leaks, and loose,
damaged, worn, or noisy parts.
The key elements of various robots can be compared by constructing a(n)
matrix
Direct labor costs comprise about
15
percent of the total cost of producing a product.
Automated equipment requires consistently uniform components to function
efficiently.
true
Installing robots reduces personal injuries and increases employee
safety.
true
Intelligent machines can do the same job as trained workers and save
labor costs by replacing those workers.
false
Most automated equipment is dedicated, or designed to perform one
function.
true
The money a business spends to purchase fixed assets is a(n) ______.
capital investment
Incorporating robots automatically increases productivity.
false
Robots can improve product quality because of their ______.
both A and B
accuracy
repeatability
Robots have the capacity to be innovative, collaborative, and think
independently.
false
When working conditions are unpleasant or unsafe, worker productivity is
affected.
true
Investments made in equipment or other business/production assets, which
are projected to prevent additional costs in the future, are called
avoidance costs
What are the three common faulty assumptions that companies make
regarding robots? Discuss why each is incorrect.
The three common faulty assumptions that companies make regarding robots
are that they automatically increase productivity, that they will save
labor costs, and that they will pay back their investment over time. They
do not automatically increase productivity because there are no machines
more flexible and more efficient than a motivated human with the proper
tools.
The product must be specifically designed for robot production,
and manual assembly benefits from specific product design as
well. Robots do not save much if any on labor costs. Labor is only
about 15% of the cost, and robots usually only replace one or two
people. In addition, skilled labor must be hired to maintain the
robot. Robots have a very high initial investment which takes a long
time to get a return on. Robots economies of scale which is difficult to
achieve in today's flexible manufacturing. Decreasing demand can
bankrupt a company.
