Why Programming and
Robotics?


Programming allows students to encode
and reflect on sequential and logical
thought in a dynamic system.
Real applications of math concepts

What is a Robot?
A Robot is a machine that can be programmed to do a task without being
directly controlled by a human being.
There are two parts to a robotic system.
1.
Hardware: This is the mechanical robot. The motors, gears, wheels,
parts, computers that make up the machine. This is the part you
build.
2.
Software: This is the instructions for the tasks and actions the robot
will do. This is the part you write.MINDSTORMS NXT is used to
create the software that controls the actions of the robot
hardware. NXT MINDSTORMS software is a visual/icon system of
assembling instructions. The flow of direction usually moves from left
to right. This software is an example of a compiled
program. Programs you write in NXT must be compiled and
downloaded to the NXT Brick before the Robot will perform the
program. (Scratch and Python are "Interpreted Languages.")
Why Robotics?

Humans are creators and builders


Robotics embody logical thought in
action through time in the real world



We like to “Give Life” to objects
“See” our thoughts in action and reaction
Robotics will continue to play bigger
roles in human society
They are cool!
Hierarchy of Technology Skills
1. Passive Reception: From creator to receiver with no action on receiver to alter
flow of content. (watching a video)
2. Active Research: From creator to receiver with receiver selecting path and
specific points of content. (Surfing the web)
3. Interactive 1 way: From creator to receiver through game model. Receiver must
master a skill to progress through activity. (Skill and Drill)
4. Communication / Expression: User creates content and art with
technology. Verbal / Text Images Plot Web
5. Interactive 2 way: creator and users interact. (Email, Blogs, Multi-User Virtual
Environments)
6. Data manipulation and Analysis: User uses computer to interact and
manipulate the content and data.
7. Software creation / programming: Users encodes logical thought and
algorithms into computer. User tells computer what to do. Provides platforms
and engines for above skill sets.
8. Hardware creation: User designs and assembles hardware to run, input, display
software.

Basic NXT-G Programming
Movement/Motor Blocks (Output)
Movement Blocks direct motors A, B, or C to rotate clockwise or counterclockwise. The
motors have sensors inside them that can measure how much they rotate. Motors C
and B usually are used for the drive wheels on a vehicle Robot. You may change the
following variables on a motor on the details window.
