Deck 3: Components of the Robot

Question 1

Which generation of controller utilizes complex mathematics to calculate the amperage draw of various motors during motion and then carefully monitors said motors to create a collaborative system?

A) Third generation
B) Fourth generation
C) Fifth generation
D) Sixth generation

Answer 1

D

Question 2

Polarity is ________________________.

A) the positive and negative orientation of components
B) used with both AC and DC
C) important only in DC circuits
D) Both a and c are correct

Answer 2

D

Question 3

What is the difference between single-phase AC and three-phase AC voltage?

Answer 3

Single-phase AC has one sine wave and points where the system has no EMF in the system.Three-phase AC has three sine waves 120 degrees apart electrically.This results in a system that always has EMF working in the system and is thus more efficient.Another benefit of three-phase AC is the fact that neutrals are not needed due to the way the sine waves interact.

Question 4

Which part of the robot is responsible for power distribution,storing and executing program data,and controlling servos?

A) Teach pendant
B) Controller
C) Manipulator
D) Base

Question 5

Which of the following configurations of batteries would result in the voltage potential of a battery being subtracted from the system?

A) A parallel setup where the positives are hooked together and the negatives are hooked together
B) A series setup where the positive of one battery is hooked to the negative of the next battery
C) A combination setup made up of multiple cells in series,connected in a parallel fashion to provide power to the system
D) A series setup where the positive of one battery is hooked to the positive of the next battery

Question 6

Axes 1-3 of the robot are often referred to as _______________.

A) pitch,yaw,and roll
B) the major axes
C) the minor axes
D) None of these are correct

Question 7

The minor axes of the robot are ___________.

A) often compared to the human wrist
B) axes 4-6
