What is a Robot?

• The lesson includes topics such as what robots are used for, what robots might be used for, and the technology in robots.

What is a robot?

• A robot is a machine designed and programmed to complete tasks quickly and accurately.
• A robot is autonomous and responds to its environment independently without constant human intervention.

Advantages of Robots

• Robots carry out repetitive work reliably and do not get bored.
• Robots work quickly, and if needed can work for 24 hours a day.
• Robots can work in dangerous environments that would be unsafe for humans.
• Robots can work in restricted spaces where humans cannot.
• Robots can work with hazardous materials like chemicals and radiation.

Where are robots used?

• Robots are being used as vital tools in the car and electronics industries.
• In manufacturing, robots complete repetitive jobs such as soldering microchips.
• Accuracy is important because small mistakes can cause processors to malfunction.
• Robots are used to paint cars, which is a hazardous job.
• Robots can perform repetitive jobs accurately and quickly, making microprocessors.
• In argriculture, drones spray crops while other robots harvest the crops.
• Tractors and other farm equipment are satellite guided.
• In medicine robots can perform surgey faster, and create 3D images of internal organs.
• Robots help doctors make a diagnosis, and can help lift patients out of bed.
• Robots can pick up goods to be sent to shops for distribution.
• Robots can deliver to buyers by culture.
• During disaster recovery, robots can help locate people.
• Disaster recovery robots use infrared sensors and can get samples.

Sensors

• Proximity sensor use infrared light beams to detect the position of nearby objects.
• Bumper switches tell a robot that it has hit something.
• Pressure pads control robots hands as they pick objects up, preventing them from crushing.

Important concepts

• Robot: A digital machine capable of automatically performing one or more tasks.
• Vision Guided Robotics: Use 2D or 3D cameras to give robots "vision" to recognize and navigate.
• Embedded Processors: Processing power is needed.
• RTOS: Real-time operating system designed to work in real-time applications where data must be processed immediately.

Fake Social Media Profile Motivations

• The reasons to create a fake social media profile is to protect yourself.
• A fake profile can allow you to express yourself without being judged.
• Allows a user to try out different personalities.
• Enables a user to share content others will be interested in.
• Users can post content to family or private content.

Risks of a Fake Profile

• Exposed to inappropriate content.
• Accidentally reveal personal views.
• Difficult to differentiate fake social media from real.

Spotting Fake Profiles

• Scrutinize the content.
• Evaluate the profile handles.
• Analyze who they follow.
• Evaluate the profile profile picture.
