Question 1

Which robot configuration uses three rotary joints to provide the greatest freedom of movement and is most commonly used in assembly and welding applications?

Accepted Answer

Articulated

Answer

Articulated robots use three or more rotary joints, mimicking a human arm, giving them the greatest range of motion for complex tasks like welding and assembly.

Question 2

In a Programmable Logic Controller (PLC), what is the primary function of the input/output (I/O) module?

Accepted Answer

Interfaces sensors and actuators with the CPU

Answer

The I/O module serves as the interface between field devices (sensors, actuators) and the PLC CPU, converting real-world signals to digital data.

Question 3

What type of sensor uses the Hall effect to detect the position of a magnetic target without physical contact?

Accepted Answer

Magnetic proximity sensor

Answer

Magnetic proximity sensors exploit the Hall effect, generating a voltage when exposed to a magnetic field, enabling non-contact position detection.

Question 4

A manufacturing cell uses a robot with a repeatability specification of ±0.05 mm. What does this value represent?

Accepted Answer

The robot's ability to return to a previously taught position consistently

Answer

Repeatability measures how consistently a robot can return to the same programmed point, not its absolute accuracy relative to a coordinate system.

Question 5

Which communication protocol is commonly used in industrial automation to connect field devices such as sensors and actuators to a PLC over a single cable?

Accepted Answer

DeviceNet

Answer

DeviceNet is a fieldbus protocol designed to connect low-level industrial devices like sensors and actuators to controllers over a single cable network.
