IGCSE Computer Science Ch6 Robotics and Automation Part 2

Transport:

• Automated transport systems include robotic systems like autonomous buses/cars, trains, and unpiloted aircraft.

• Automated systems are also used in manually controlled transport, such as cars, buses/lorries, trains, and aircraft.

• Examples include automatic signal control systems in modern trains and automatic pilots in airplanes.

• Self-parking systems use sensors to identify suitable parking spaces and operate steering, brakes, and throttle for automatic parking.

Transport:

• Advantages of automated parking systems:

  • More efficient use of parking spaces

  • Reduced traffic disruption

  • Ability to fit into smaller spaces

  • Fewer dents and scratches to cars

  • Enhanced safety with object monitoring

  • Consistent results

Transport:

• Disadvantages of automated parking systems:

  • Over-reliance on automation

  • Potential for malfunction due to faulty sensors

  • Difficulty detecting low kerbs

  • High initial cost with additional maintenance.

Multiple Choice

What are some advantages of automated parking systems?

• Increased insurance claims

• Longer parking times

• Fewer dents and scratches to cars

• Manual control of steering and brakes

Multiple Choice

What is the primary function of sensors in an automated self-parking system for cars?

• Increased insurance claimsTo control the throttle and brakes

• To determine the driver's preference for parking

• To calculate the position of objects in the car's vicinity

• To remotely monitor the vehicle's speed

Multiple Choice

In automated transport systems like autonomous cars, what is a potential disadvantage of over-reliance on automation by the driver?

• Improved safety on the road

• Enhanced driving skills of the driver

• Loss of driving skills in the driver

• Reduced insurance premiums for the driver

Adaptive Cruise Control:

• Adaptive cruise control uses sensors, on-board computers, and actuators to maintain a safe distance from other vehicles.

• Drivers set a cruising speed, and lasers in the car's bumpers measure distances to the vehicle in front.

• The on-board computer adjusts speed using actuators, either applying brakes or adjusting throttle, to maintain a safe following distance.

Multiple Choice

How does adaptive cruise control adjust a car's speed to maintain a safe following distance?

• It relies on the driver's manual adjustments.

• It uses radar to scan the surrounding environment.

• It applies the brakes automatically.

• It disconnects the accelerator pedal.

Multiple Choice

What is the purpose of the lasers set into the car's bumpers in adaptive cruise control?

• They illuminate the road for better visibility

• They measure the distance to the vehicle in front.

• They provide GPS navigation

• They communicate with other cars on the road.

Agriculture:

• Automated systems in agriculture, particularly in irrigation, involve robotics and wireless transmission.

• In Brazil, irrigation is automated, with data received from weather stations and ultrasonic water level sensors in fields.

• Wireless transmission sends data from sensors to a controller, which decides when to start or stop water pumps.

• A supervisor remotely monitors the system and can override the controller.

Agriculture:

• Advantages of automated irrigation:

  • Reduced labor costs

  • Efficient control of irrigation

  • Better resource management

  • Faster response

  • Improved safety

  • Customized irrigation for different crops.

Agriculture:

• Disadvantages of automated irrigation:

  • High initial setup costs

  • High maintenance costs

  • Increased need for channel maintenance.

Multiple Choice

What is a disadvantage of automated irrigation systems in agriculture?

• Reduced labor costs

• Enhanced human interaction

• Increased maintenance of water channels

• Minimal control of water supply

Multiple Choice

What is one of the advantages of automated irrigation systems?

• High labor costs

• Inefficient control of irrigation

• Faster response than a human

• Overuse of water resources
