Question 1

The driven gear _____________.
A) is the gear that supplies power to the gear train,often tied to a motor
B) is a gear set with multiple gears on one shaft
C) is the gear tied to the gear train's output
D) is used primarily to change the direction of a gear train's output

Accepted Answer

The driven gear is the gear tied to the gear train's output, receiving motion and power from the driving gear to perform its function.

Question 2

Which type of robotic system is known for a cubic or rectangular work envelope?
A) Spherical
B) Articulated
C) Cartesian
D) Delta

Accepted Answer

Cartesian robots are known for their cubic or rectangular work envelope, which is defined by their linear movements along the X, Y, and Z axes.

Question 3

The compound gear _____________.
A) is the gear tied to the gear train's output
B) is the gear that supplies power to the gear train,often tied to a motor
C) is used primarily to change the direction of a gear train's output
D) is a gear set with multiple gears on one shaft

Accepted Answer

A compound gear refers to a configuration where multiple gears are mounted on a single shaft. This setup allows for complex gear ratios and adjustments in a compact space, often used in machinery to achieve desired speed or torque outputs efficiently.

Question 4

The drive gear _____________.
A) is used primarily to change the direction of a gear train's output
B) is the gear that supplies power to the gear train,often tied to a motor
C) is the gear tied to the gear train's output
D) is a gear set with multiple gears on one shaft

Accepted Answer

The drive gear is the gear that supplies power to the gear train, often connected to a motor, initiating the movement within the gear system.

Question 5

Which type of robotic system is currently the most popular with industry?
A) Cartesian
B) Articulated
C) Delta
D) Spherical

Question 9

Which type of robotic system sacrifices a large portion of its work envelope for speed and the benefit of over-the-work mounting?
A) Delta
B) Cylindrical
C) Cartesian
D) SCARA

Accepted Answer

Delta robots are designed for speed and can be mounted over the work area, but this design choice means they sacrifice a large portion of their potential work envelope compared to other types of robotic systems.

Question 10

A common power source for robot tooling is _________ power.
A) hydraulic
B) pneumatic
C) AC
D) DC

Accepted Answer

Question 11

_______ robots blend linear Cartesian motion with articulated rotation to create a new motion type that is often used in the electronics field.
A) Cartesian
B) Cylindrical
C) SCARA
D) Polar

Accepted Answer

SCARA robots combine linear Cartesian motion with articulated rotation, making them highly suitable for precise, high-speed work in the electronics industry.

Question 12

When using gearing or some other power transmission system to reduce speed,the system often _______ torque.
A) gains
B) loses
C) has the same amount of
D) None of these are correct

Accepted Answer

When using gearing or another power transmission system to reduce speed, the system often gains torque. This is due to the principle of conservation of energy, where a decrease in speed (or angular velocity) through gearing results in an increase in torque to conserve the overall power transmitted through the system.

Question 13

The idler gear _____________.
A) is used primarily to change the direction of a gear train's output
B) is the gear tied to the gear train's output
C) is a gear set with multiple gears on one shaft
D) is the gear that supplies power to the gear train,often tied to a motor

Accepted Answer

The idler gear is used primarily to change the direction of rotation in a gear train. It does not directly affect the gear train's output, supply power, or consist of multiple gears on one shaft.

Question 14

The most common power source for industrial robot motion is _________ power.
A) AC
B) hydraulic
C) pneumatic
D) DC

Accepted Answer

AC power is the most common power source for industrial robots due to its efficiency and ability to handle high power loads required for industrial applications.
