Question 2 of 21

Which of the following characteristics is part of the definition of an industrial robot?

... Both of these characteristics describe an industrial robot, which the International Organization for Standards defines as "an automatically controlled, reprogrammable, multipurpose manipulator programmable in three or more axes, which may be either fixed in place or mobile for use in industrial automation applications."

Question 3 of 21

Industrial robotics sales nearly doubled worldwide between 2009 and 2010. How many units were sold in 2010?

... In 2010, 118,337 robotics units were sold.

Question 4 of 21

Which industry was among the biggest buyers that helped spur the 2010 growth in sales?

... The stellar growth in robotics in 2010 was due chiefly to the automotive industry, with a secondary nod to electronics manufacturing.

Question 5 of 21

Which part of the world buys the bulk of industrial robotics gear?

... Industrial robot sales in 2010 came primarily from Asia. Asian industries bought about 70,000 units that year. The U.S. bought about 14,380 units, Europe around 30,600 and Canada slightly more than 1,000.

Question 6 of 21

Are industrial robots servo or non-servo controlled?

... All industrial robots are one or the other. Servo robots can be controlled by sensors and can offer feedback on their operation. Non-servo robots can't offer feedback and are instead controlled by mechanical stops and limit switches.

Question 7 of 21

Which of the following is NOT among the main components of an industrial robot?

... An industrial robot is comprised of a mechanical unit, power source, tooling and a control system.

Question 8 of 21

Which type of power source is most often used for industrial robot actuators and controllers?

... Electrical actuators and controllers are the most common in industry. These units rely on AC or DC power to manipulate electromechanical mechanisms and their associated control systems.

Question 9 of 21

Who is often referred to as the "father of robotics"?

... Joseph F. Engelberger has been called the father of robotics for working with George Devol to develop the first industrial robot, the Unimate. The device was built in the late 1950s and first used in industry in 1961 at a General Motors plant in Trenton, N.J.

Question 10 of 21

Which country was most receptive to Engelberger's early championing of industrial robots?

... Engelberger has said that despite GM's order of 36 additional Unimates, U.S. interest in robotics was tepid compared to the unbridled enthusiasm his work received in Japan, which eagerly embraced robotics as a means to help with its economic expansion.

Question 11 of 21

What was the worldwide market value of robotic systems in 2010?

... In 2010, the worldwide market value of robotic systems, including associated software, peripherals and engineering, was estimated to be $17.5 billion by the International Federation of Robotics.

Question 12 of 21

How does NASA use industrial robots?

... While NASA uses robotics for all kinds of applications, such as in unmanned aircraft, rovers, space telescopes and space shuttle repairs, its "industrial" use of robots involves the manufacture of rocket materials.

Question 13 of 21

How much weight can the record-breaking KUKA KR 1000 Titan robot lift?

... The industrial robot named KR 1000 Titan, manufactured by Germany's Kuka Roboter GmbH, has a payload capacity of 1,000 kilograms, which is more than 1 short ton. The KR 1000 titan's nine motors can lift five times the weight of the robot itself.

Question 14 of 21

In robotics, what are degrees of freedom?

... The term "degrees of freedom" refers to the number of ways in which a thing can move in three-dimensional space. Industrial robots usually have between three and six degrees of freedom, corresponding with the number of axes a machine employs. For example, a basic robot with three degrees of freedom can move up and down, left and right and forward and backward.

Question 15 of 21

Which drive system gives an industrial robot the most strength?

... Hydraulic drives will give a robot the most speed and strength. Pneumatic systems are used with smaller robots that have fewer axes, and electrical systems simply don't have the speed and strength of a hydraulic system.

Question 16 of 21

What is the technical term for a robot's "hand"?

... The piece at the end of an industrial robot's arm is called an end effector. It's the part of the robot that deals directly with the materials with which the unit is programmed to work. It can function as a gripping tool, a vacuum, a suction grip, a magnet or even a welding torch.

Question 17 of 21

According to several studies, most industrial robot accidents occur:

... Swedish and Japanese studies have demonstrated that a greater number of accidents occur during the programming, maintenance, testing and repair phases of a robot's operation than occur during normal use. It is during such "down" phases that an operator may encroach on a robot's work area. Injuries can result if there are malfunctions at that time.

Question 18 of 21

Which of the following are among the types of paths a robot can follow?

... Industrial robots can generate three types of path: point-to-point (moving from one discrete point to another), controlled (the robot's arm follows a predictable, controlled path and orientation as it moves) and continuous (the path is controlled by a large number or close succession of spatial points stored in memory).

Question 19 of 21

What is a teach pendant?

... A teach pendant is a device used in conjunction with a robot controller to move, program and run industrial robots. The hand-held unit, about the size of a tablet PC, typically has a keypad, a display and an emergency kill switch. The person programming the robot is often called the "teacher."

Question 20 of 21

Which activity is NOT performed by an industrial robot?

... Industrial robots can do lots of things, including welding (one of their most common uses), material handling, painting, cleaning, polishing and even plasma cutting (cutting metals with a plasma torch). Industrial robots do not pilot aerial vehicles.

Question 21 of 21

What is a work envelope?

... A robot's work envelope is the area in which it makes its living. The maximum envelope is all of the space that the robot, including its end effector, can possibly reach. The restricted envelope, meanwhile, defines the part of the maximum envelope to which a robot is restricted by devices that limit its movement. The operating envelope is the smaller space that is actually used by the robot performing its tasks.
