Which of the following are true of encoders?

Both of the above.

Which of the following window components are displayed in RoboCell's Simulation & Teach mode?

Chon het

Adjusting the Roll rotates the gripper about the Y-axis.

False

RoboCell allows you to move the robot in directions that exceed its actual working space since it is simulation software and does not have to accurately reflect reality.

False

The Go Circular command moves the robot TCP in an arc between two points through a defined intermediary point. In this circular trajectory motion, the robot visibly stops at three positions - the first point of the arc, the intermediary point and the last point of the arc.

False

The Run Continuously option runs the program continuously if the operator resets the workcell at the end of each cycle.

False

For which of the following devices can positions be recorded?

For both a robot and a peripheral device.

Which of the following options may prevent a robot from reaching all the positions that are found in its work envelope?

Mechanical limitations.

Which two of the following types of joints are commonly used in robot manipulators?

Prismatic joints Resolute joints

The Robotics Institute of America defines a robot as being:

Re-programmable Multifunctional Manipulator

Which of the following methods could be used to increase the productivity of a program by cutting down the running time?

Recording single positions for the robot and the rotary table.

Which of the following commands does not affect program execution?

When an axis is set to zero using the SA command, which of the following will happen to the encoder counts for that axis?

The encoder value for the axis will change to zero without changing the position of the axis.

Which of the following characteristics of the SCORBOT ER 4u qualify it as a vertical articulated robot?

The first three joints of the robot are revolute joints.

Which of the following characteristics of a stand-alone robot limits its capacities?

The robot is in a fixed position and can therefore only move a tool within a limited environment.

Which of the following options is a possible disadvantage of including numerous intermediate positions between two positions?

The robot will stop and start a number of times between the two end positions.

What is a degree of freedom in robotics?

The robot's ability to move its tool along or around an axis.

A robot's work envelope is defined as:

The span of the robot's working range.

Which of the following options best describes the changes to a program execution caused by the Set Variable command?

There were no noticeable changes to the program execution.

Which of the following options best describes the changes to the program execution caused by the Remark command?

There were no noticeable changes to the program execution.

An encoder counts pulses to determine the number of revolutions the disk and motor have completed.

True

Given a defined unit of measurement, and a defined coordinate system, a point in space can have more than one set of coordinates in the Cartesian coordinate system.

True

If the reference position of a relative position does not change, the relative position is virtually absolute (does not change).

True

Positions recorded on ground level are typically named with single digits while positions directly above them may be named with multiple digits.

True

When a robot is moved along a linear slidebase, the robot positions and the robot's work envelope move together with the robot.

True

When working online with an actual robot, Send Robot options can be used to simplify the recording positions task.

True

Which of the following commands is best for the simulated welding operation?

Using the Go Linear command.

Which of the following commands pauses the execution of the program for a predetermined period of time?

Wait command.

Why is it easier to move the TCP in straight lines when in XYZ mode?

Working in XYZ enables you to move the TCP along one cartesian axis at a time.

Which of the following window components are displayed in Teach & Edit mode?

Workspace Window Teach Positions Dialog Box Program Window

Which of the following methods have you used to record or teach robot positions?

a. Manually moving the robot to the required position using the Manual Movement dialog box & recording the position. b. Entering specific angle values in the Teach Position dialog box & then teaching the position. c. Entering an offset in the Teach Position dialog box & then teaching the position as relative to another position. d. Entering specific Cartesian coordinates in the Teach Position dialog box & then teaching the position. (Chon het)

A RoboCell project is comprised of which of the following files?

a. Project file b. 3D Graphics Cell file c. Positions file d. Program file (chon het)

Which of the following coordinates represent a TCP position that is 50 mm above table level?

c. (0, 120, 50) d. (300, 200, 50)

Which of the following options would enable you to increase the robot's work envelope?

Adding accessories to the robot that move objects in and out of the robot's reach. Increasing the length of the robot arm.

Which of the following options describes the Follow Me Camera viewing tool?

Adjusts the viewing angle to follow the movements of any selected object.

Which of the following difficulties are encountered when manually manipulating the gripper?

All the answers are correct.

What is the system response to an encounter between the robot arm and the table?

An impact error message is displayed and the robot arm cannot be lowered further.

The encoder produces approximately 14,232 pulses for a complete revolution of the rotary table. Therefore, when the rotary table turns 90 degrees, the encoder produces:

3,558 pulses
