Robotics and Automation (Junior Cert Applied Technology): Revision Notes
📚 Revision Notes
Robotics
Overview
- Importance of Robots: Robots make work more accurate and safe in factories, hospitals, exploration places (like oceans and space), and homes.
- Role in Industries: They take over tasks that people usually do, making work easier.
infoNote
Robots play a critical role across multiple domains, enhancing efficiency and safety while mitigating risks.
Definitions
- Manufacturing Industries: Robots work on assembly lines, doing tasks with care and speed.
- Healthcare Robots: Used in operations and patient care for better precision and help during healing.
- Exploration Robots: Used in deep-sea and space to collect data where people can't go.
- Dangerous Area Robotics: Work in risky areas to keep people safe.
- Bomb Disposal Robots: Made to disable bombs safely.
- Home Devices Robots: Like robotic vacuums and other home devices.
Industrial Applications
- Manufacturing: Robots make things fast and accurate, especially for making cars.
- Healthcare: Robotic surgery is precise; exoskeletons help with movement and health checks.
- Exploration: Helps gather information from places hard to reach.
- Dangerous Areas: Safely handle dangerous materials.
- Bomb Disposal: Safely takes apart bombs from a distance.
- Home Devices: Robots in vacuum cleaners and other gadgets for daily house tasks.
Advantages
infoNote
Understanding the advantages of robots can lead to better implementation and integration in various fields.
- Accuracy: Gets tasks done with high precision.

- ROM: Permanent memory
Degrees of Freedom
infoNote
Degrees of freedom define the movement capabilities of robots, influencing complexity and cost.
- How many separate moves a robot can make.
- More moves let robots do complex tasks but cost more.
Power Sources
- Electricity: Main energy source for robots.
- Pneumatics: Uses air for easy tasks.
- Hydraulics: Best for tough tasks like construction.
Global Variation
- Robots are common in richer nations due to cost.
infoNote
Robotics are increasingly accessible as costs decrease, leading to greater use in developing regions.
- Increasing use in poorer regions as they get cheaper.
Summary
infoNote
- Broad Role: Robots are important in many fields.
- Advantages and Disadvantages: Highlights main benefits and issues.
- Control & Power: Important for robot use.
- Global Spread: Varies by wealth and cost.
