Which robot configuration uses three rotary joints to provide the greatest freedom of movement and is most commonly used in assembly and welding applications?
Answer: Articulated
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.
In a Programmable Logic Controller (PLC), what is the primary function of the input/output (I/O) module?
Answer: Interfaces sensors and actuators with the CPU
The I/O module serves as the interface between field devices (sensors, actuators) and the PLC CPU, converting real-world signals to digital data.
What type of sensor uses the Hall effect to detect the position of a magnetic target without physical contact?
Answer: Magnetic proximity sensor
Magnetic proximity sensors exploit the Hall effect, generating a voltage when exposed to a magnetic field, enabling non-contact position detection.
A manufacturing cell uses a robot with a repeatability specification of ±0.05 mm. What does this value represent?
Answer: The robot's ability to return to a previously taught position consistently
Repeatability measures how consistently a robot can return to the same programmed point, not its absolute accuracy relative to a coordinate system.
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?
Answer: DeviceNet
DeviceNet is a fieldbus protocol designed to connect low-level industrial devices like sensors and actuators to controllers over a single cable network.
In servo drive systems, what is the role of the encoder mounted on the motor shaft?
Answer: Provides position and velocity feedback to the controller
The encoder generates pulses proportional to shaft rotation, feeding position and velocity data back to the servo controller for closed-loop control.
What is the primary purpose of a teach pendant in industrial robotics?
Answer: Manually guiding and programming robot positions and movements
A teach pendant is a handheld device used by operators to manually jog the robot, teach positions, and write or edit programs directly on the robot controller.
