Lesson 7 ROBOTICS

What is the primary function of an end effector in a robot?

• To provide power to the robot

• To control the robot's movements

• To program the robot

• To interact with objects in the environment

Answer explanation

The primary function of an end effector in a robot is to interact with objects in the environment. It serves as the tool or device that allows the robot to perform tasks such as gripping, manipulating, or assembling items.

Which type of industrial robot is characterized by rotary joints?

• Articulated

• Cylindrical

• Delta

• Cartesian

Answer explanation

Articulated robots are defined by their rotary joints, allowing for a wide range of motion similar to a human arm. This makes them ideal for tasks requiring flexibility and precision, distinguishing them from other robot types.

What type of robot movement is associated with tracks?

• Wheeled movement

• Continuous movement

• Flying movement

• Legged movement

Answer explanation

Tracks enable robots to move continuously over various terrains, providing stability and traction. This type of movement is distinct from wheeled, flying, or legged movements, making 'continuous movement' the correct choice.

Which programming method allows for robot programming without disrupting operations?

• Teaching Pendant

• Simulation/Offline Programming

• Teaching by Demonstration

• Direct Coding

Answer explanation

Simulation/Offline Programming allows for programming robots without interrupting ongoing operations, as it enables the creation and testing of programs in a virtual environment before deployment.

What is a common application for SCARA robots?

• Painting

• Material removal

• Assembly tasks

• Welding

Answer explanation

SCARA robots are commonly used for assembly tasks due to their ability to perform precise movements in a horizontal plane, making them ideal for tasks like picking, placing, and assembling components efficiently.

Which type of motor allows for precise control of movement in robots?

• Induction motors

• Stepper motors

• DC motors

• AC motors

Answer explanation

Stepper motors allow for precise control of movement by moving in fixed steps, making them ideal for applications requiring accuracy, such as in robotics. Other motor types, like induction and DC motors, do not provide this level of precision.

What is the main advantage of using a teach pendant?

• It eliminates the need for training

• It allows for precise positioning

• It can be used offline

• It reduces programming time

Answer explanation

The main advantage of using a teach pendant is that it allows for precise positioning of robotic arms, enabling accurate and repeatable movements essential for tasks like assembly and welding.

Which type of robot is designed to operate in a cylindrical work envelope?

• Polar robot

• Delta robot

• Articulated robot

• Cylindrical robot

Answer explanation

A cylindrical robot operates within a cylindrical work envelope, allowing it to reach various points in a cylindrical area. This makes 'Cylindrical robot' the correct choice for the question.

What is the purpose of force-torque sensors in robotic applications?

• To measure speed

• To provide power

• To control the force applied

• To enhance mobility

Answer explanation

Force-torque sensors are crucial in robotics as they measure the forces and torques applied by the robot. This data allows for precise control of the force applied during tasks, ensuring safety and accuracy in operations.

Which type of robot is known for its spider-like structure?

• Cylindrical

• Delta

• Articulated

• SCARA

Answer explanation

The Delta robot is known for its spider-like structure due to its three arms connected to a common base, allowing for high speed and precision in movement, resembling a spider's legs.
