Self-driving cars use precision sensors to see 360 degrees. They navigate on their own with no human driver or remote control. The car uses roof-mounted laser rangefinders, radars, cameras, and a GPS (Global Positioning System) receiver to sense its environment and maneuver in traffic. It is now legal in CA & Nevada to put a self-driving car on the highway.

3-D printers use digital blueprints to create physical objects. About the size of a microwave, a few years ago, 3-D printers were as big as industrial refrigerators and cost hundreds of thousands of dollars. Researchers and early adopters have made everything from cute figurines and jewelry to working bicycles. A lot of iPhone cases are being custom-made on 3-D printers.

Group Discussion:

1. Who is legally responsible for (a self-driving car, or for the devices you create)?

2. Should minors be allowed (to travel alone in self-driving cars; unlimited access to 3-D printers)?

3. What are the cons/dangers associated with self-driving cars and 3-D printing?

REMEMBER

• Being Computer Fluent will save you money, make you more productive, help you protect your identity, and your computer

• Charles Babbage, Ada Lovelace, Steve Jobs, Steve Wozniak, Tim Berners-Lee, Marc Andreessen, Bill Gates a few of those that created our computer history

• ENIAC, Altair, Mosaic - some firsts in computer history

• 5 Generations, 4 switches in computer history

• The Military, Apple, Microsoft, the Internet helped change our daily lives

• Computers of today are tomorrow’s history
