1. What is a robot?

2. UNIT 1 Overview What it covers:
This unit begins with a look at robots in general, followed by an introduction to the NXT robotics kit. Student then explore the NXT kit, learn about structural building, gearing and Faraday's Law. The culminating project has students combine all this learning into the creation of an NXT-based Faraday Golfing Machine.
Lessons in this Unit: 
What is a Robot?
Introduction To Mindstorm EV3
EV3 Kit Overview
EV3 Parts Exploration
Gears: An Introduction
An Example Project

3. Lesson 1
Overview: 
The goal of this lesson is to draw out student's preconceptions of robots and explore the variety and ambiguity of "What is a Robot?"
Objectives: 
Students will be able to:
1. List examples of robots (real and fictional)
2. State characteristics of a robot
3. Describe examples of how robots sense their environment
4. Describe examples of how robots follow instructions
5. Identify different types of robots and state an example of each
6. Describe reasons humans use robots in certain applications

4. What is a robot?
What are the distinguishing characteristics of a robot? (How can you tell whether something is a robot, or not)?
It is manufactured (man-made, does not occur in nature)
It can sense its environment
It can respond to instructions
What are some examples of robots?
Real robots
Fictional robots
Describe how these robots match the three characteristics above:

5. What is a robot? What is the difference between a robot and a machine?
Some feel a machine must also be capable of movement to be a robot.
What do you think?
Why?
What about a Washing Machine?
Is this a robot, or a machine?
What about an electronic gate at a railway crossing?

6. What is a robot: The 5 d
The 5 D's is short for dirty, dull, dangerous, domestic and dexterous. These are the different kinds of robots used in the human society. There are many jobs which humans would rather leave to robots because it's easier, safer or more productive. 
Dirty- Robots which are classified in the dirty section tends to do the jobs that are to dirty or sometimes a bit dangerous to do such as inhaling fumes. They do the jobs like spray paint cars, move things back and forth through mines and mine things out of the ground. There is also a specialty about this, robots dont have to be paid or eat or anything except the occasional breakdown, where you would need to hire an engineer or something to fix it.
Dull- Robots which are dull generally do the jobs which are boring and needs to be repeated over and over such as putting lids on bottles, putting toys together or even being a trough. These robots save humans from doing boring work over and over again.
Dangerous- These robots do the dangerous jobs like defuse bombs, walk on Mars, handle nuclear plants and other dangerous jobs that could have taken the lives of many human beings. These jobs are much more safer for human beings and saves lots of lives.
Dexterous- Dexterous Robots are used for the precision with their arms able to move things small and soon will be able to do hospital jobs on humans where it can do with perfect precision. These robots will be able to take over doctors and will save many lives.
Domestic- These robots are used for cleaning such as the Roomba, automatic lawn mowers or things that has emotions and can answer you such as a ferbie, mechanical dogs or robo raptors. They are to help humans do cleaning jobs without all the fuss.
