Robotics II - Final Exam

The type of signal used to control a servo motor is:

• Analog signal

• Digital signal

• Pulse width modulated (PWM) signal

• Continuous current

The typical maximum rotation angle of a standard closed-loop servo motor is:

• 90°

• 180°

• 270°

• 360°

The internal gears in a servo motor reduce speed and increase:

• Torque

• Voltage

• Current

• Temperature

The component inside the servo that provides position feedback is:

• Potentiometer

• Gearbox

• DC Motor

• Microcontroller

A torque rating of 25 kg-cm means:

• The motor can lift a 25 kg weight at a distance of 1 cm from the shaft.

• The motor can lift a 1 kg weight at a distance of 25 cm from the shaft.

• The motor can lift a 25 kg weight at a distance of 25 cm from the shaft.

• The motor can lift a 1 kg weight at a distance of 1 cm from the shaft.

What type of movement do stepper motors primarily provide?

• Rotary movement

• Linear movement

• Oscillating movement

• Random movement

What is the main component that allows a stepper motor to move in discrete steps?

• Rotor

• Stator

• Commutator

• Brushes

A common application where stepper motors are used due to their precise movement is:

• Electric fans

• 3D Printers

• Ceiling lights

• Water pumps

What powers the actuators in a robotic arm?

• Electricity, Air, Liquids

• Plasma

• Sun

• Blood

A major benefit of robotic arms in logistics is:

• Increased efficiency

• Higher energy consumption
