What is the primary function of a robot's actuator?

  1. To generate electrical signals

  2. To convert electrical signals into mechanical motion

  3. To sense the environment

  4. To process data


Correct Option: B
Explanation:

Actuators are responsible for converting electrical signals from the robot's controller into mechanical motion, enabling the robot to move and perform tasks.

Which type of sensor is commonly used in robots to detect obstacles and avoid collisions?

  1. Accelerometer

  2. Gyroscope

  3. Ultrasonic sensor

  4. Infrared sensor


Correct Option: C
Explanation:

Ultrasonic sensors emit high-frequency sound waves and measure the time it takes for the waves to bounce back from objects. This information is used to determine the distance between the robot and the objects, helping it to avoid collisions.

What is the function of a robot's controller?

  1. To generate electrical signals

  2. To convert electrical signals into mechanical motion

  3. To sense the environment

  4. To process data and make decisions


Correct Option: D
Explanation:

The controller is the brain of the robot. It receives sensory data from the environment, processes it, and makes decisions about how the robot should respond.

Which type of robot joint allows for rotation around a single axis?

  1. Revolute joint

  2. Prismatic joint

  3. Spherical joint

  4. Universal joint


Correct Option: A
Explanation:

A revolute joint allows for rotation around a single axis, enabling the robot to move in a circular motion.

What is the purpose of a robot's end effector?

  1. To generate electrical signals

  2. To convert electrical signals into mechanical motion

  3. To sense the environment

  4. To interact with the physical world


Correct Option: D
Explanation:

The end effector is the part of the robot that directly interacts with the physical world. It can be a gripper, a welding tool, a painting tool, or any other device that allows the robot to perform a specific task.

Which type of robot transmission is commonly used to reduce the speed and increase the torque of a motor?

  1. Gear train

  2. Belt drive

  3. Chain drive

  4. Hydraulic drive


Correct Option: A
Explanation:

A gear train is a series of gears that mesh together to transmit motion and power. It can be used to reduce the speed and increase the torque of a motor, allowing the robot to perform tasks that require high force.

What is the purpose of a robot's power supply?

  1. To generate electrical signals

  2. To convert electrical signals into mechanical motion

  3. To sense the environment

  4. To provide energy to the robot's components


Correct Option: D
Explanation:

The power supply provides energy to the robot's components, such as the controller, actuators, and sensors. It can be a battery, a fuel cell, or any other energy source.

Which type of robot sensor is commonly used to measure the robot's position and orientation?

  1. Accelerometer

  2. Gyroscope

  3. Encoders

  4. Inertial Measurement Unit (IMU)


Correct Option: D
Explanation:

An Inertial Measurement Unit (IMU) combines accelerometers, gyroscopes, and sometimes magnetometers to measure the robot's position, orientation, and acceleration.

What is the function of a robot's gripper?

  1. To generate electrical signals

  2. To convert electrical signals into mechanical motion

  3. To sense the environment

  4. To grasp and manipulate objects


Correct Option: D
Explanation:

A gripper is a mechanical device that allows the robot to grasp and manipulate objects. It can be a simple two-fingered gripper, a multi-fingered gripper, or a specialized gripper designed for a specific task.

Which type of robot joint allows for movement in two perpendicular axes?

  1. Revolute joint

  2. Prismatic joint

  3. Spherical joint

  4. Universal joint


Correct Option: D
Explanation:

A universal joint allows for movement in two perpendicular axes, enabling the robot to move in a more complex manner.

What is the purpose of a robot's feedback system?

  1. To generate electrical signals

  2. To convert electrical signals into mechanical motion

  3. To sense the environment

  4. To monitor and adjust the robot's behavior


Correct Option: D
Explanation:

A feedback system monitors the robot's behavior and makes adjustments to ensure that it performs as desired. This can involve adjusting the robot's position, orientation, or velocity.

Which type of robot sensor is commonly used to detect the presence of objects without physical contact?

  1. Accelerometer

  2. Gyroscope

  3. Ultrasonic sensor

  4. Infrared sensor


Correct Option: D
Explanation:

Infrared sensors emit infrared light and measure the amount of light that is reflected back from objects. This information is used to detect the presence of objects without physical contact.

What is the function of a robot's motor?

  1. To generate electrical signals

  2. To convert electrical signals into mechanical motion

  3. To sense the environment

  4. To process data


Correct Option: B
Explanation:

Motors are responsible for converting electrical signals from the robot's controller into mechanical motion, enabling the robot to move and perform tasks.

Which type of robot joint allows for movement in all three axes?

  1. Revolute joint

  2. Prismatic joint

  3. Spherical joint

  4. Universal joint


Correct Option: C
Explanation:

A spherical joint allows for movement in all three axes, providing the robot with a wide range of motion.

What is the purpose of a robot's gearbox?

  1. To generate electrical signals

  2. To convert electrical signals into mechanical motion

  3. To sense the environment

  4. To change the speed and torque of a motor


Correct Option: D
Explanation:

A gearbox is a mechanical device that changes the speed and torque of a motor. It allows the robot to operate at different speeds and torques, depending on the task it is performing.
