An engineer is designing a robotic exploration buggy for rough, dirty terrain. The buggy must automatically detect obstacles before it comes into contact with them. Determine the best input sensor for this application.
Proximity sensor
Contact bump switch
Temperature sensor
Light-dependent resistor (LDR)
For a robotic exploration buggy that must detect obstacles before contact, select all statements that correctly justify how a proximity sensor achieves this function.
It uses an emitted infrared or electromagnetic field to detect obstacles before contact.
It looks for a return signal or response from the environment to that field.
When a return is received, it sends a signal to the control device indicating an object is in the path.
It requires physical contact with an object to detect it.
The buggy’s sensor control system is to use wireless signal connections. Select all reasons why wireless control would be appropriate for this application.
Wired connections may become loose or dirty in rough terrains, causing signal communication failures.
Wireless systems have simpler maintenance and installation than wired systems, reducing time and cost.
Avoids issues with wire length that could snag or be too long for the buggy to drag.
Wireless control always provides higher sensor precision than wired connections.
An engineering company performs planned maintenance on CAM machinery. The company provides standard operating procedures (SOPs) for their engineers to follow when carrying this out. Explain why the maintenance engineers must follow the provided SOPs when working on this machinery.
To ensure consistency of maintenance procedures on computer operated/programmed machinery
To ensure conformance with standards specific to the CAM machinery being worked on
To ensure safe mechanical/electrical/computer-operated operation of the machinery after maintenance
To avoid potential legal repercussions from unsafe or non‑standard work on CAM machinery
To reduce product design time for new models
An engineering company produces CAD designs of mechanical components for vacuum cleaners. The company employs 20 design engineers and five members of staff responsible for general administration work. Give one example of a direct cost that the company might have and why it is needed.
Cost of design engineer labour, as their skill and expertise are needed to produce project‑specific CAD drawings/models
Office rent, as space is needed for day‑to‑day activities
