Introduction to Robotics Exam

A ____________ and ____________ machine designed to move materials, tools or specialized instruments, by programmed movements to carry out a variety of tasks.

• Reprogrammable and Multifunction

• Programmable and functional

• Programmed and multifunctional

• Specialized and skilled

Answer explanation

The correct choice is 'Reprogrammable and Multifunction' because it accurately describes a machine that can be programmed for various tasks and can be reprogrammed for different functions, aligning with the question's requirements.

Who coined the term robotic and published the three famous laws of robotics?

• Isaac Asimov

• Isaac Newton

• Isaac Stewart

• Isaac Sherill

Answer explanation

The term 'robotic' and the three laws of robotics were coined by Isaac Asimov, a science fiction writer. His laws have significantly influenced the field of robotics and ethical discussions surrounding artificial intelligence.

How many degrees of freedom is needed to locate a robot’s Hand at any point in its workspace?

• 6

• 8

• 4

• 12

Answer explanation

A robot's hand requires 6 degrees of freedom to move freely in 3D space: 3 for position (x, y, z) and 3 for orientation (roll, pitch, yaw). Thus, the correct answer is 6.

What are the three degrees of freedom located in the arm of a robotic system

• Rotational, Radial and Vertical

• Vertical, Horizontal and Circular

• Up, down, and around

• 90 degrees, 180 degrees and 360 degrees

Answer explanation

The correct answer is 'Rotational, Radial and Vertical' as these terms describe the three degrees of freedom in a robotic arm, allowing it to move in various directions and orientations effectively.

The following degrees of freedom pitch, yaw and roll are located in which part of the robotic arm?

• Base

• Joint

• Traverse

• Wrist

Answer explanation

The degrees of freedom pitch, yaw, and roll are associated with the wrist of a robotic arm, allowing for precise orientation and movement of the end effector.

A robotic joint provides relative motion between how many links of the robot?

• 4

• 2

• 3

• 5

Answer explanation

A robotic joint connects two links of a robot, allowing them to move relative to each other. Therefore, the correct answer is 2, as it provides motion between these two links.

How many degrees of freedom is normally associated with each joint?

• 1

• 2

• 4

• 5

Answer explanation

Each joint in the human body typically has 1 degree of freedom, allowing for movement in one plane. This is true for hinge joints like the elbow, which can flex and extend but not rotate.

Name the following joint:

• Linear

• Twising

• Orthogonal

• Revolving

Answer explanation

The correct answer is 'Linear' because it describes a type of joint that allows movement along a straight line, unlike the other options which refer to different types of motion or joint characteristics.

Name the following joint:

• Rotational

• Revolving

• Twisting

• Orthogonal

Answer explanation

The correct answer is 'Rotational' because it describes a joint that allows for rotation around an axis, distinguishing it from the other options which refer to different types of movements.

Name the following joint

• Rotational

• Orthogonal

• Revolving

• Twisting

Answer explanation

The correct answer is 'Linear' because a linear joint allows movement along a straight path, unlike rotational or revolving joints which allow for circular motion. Orthogonal joints refer to angles, not movement types.
