Objectives Build Basic Vehicle
Robot from directions Using NXT-G software Distance, Direction,
Duration Sensors Missions Application to Math and
Science Standards
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 Distance, Direction, Duration Boolean Concepts
Develops Technological Fluency
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
We like to “Give Life” to objects Robotics embody logical thought in
action through time in the real world “See” our thoughts in action and reaction
Robotics will continue to play bigger roles in human society
They are cool!
Hierarchy of Technology Skills1. 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 Web5. 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 ProgrammingMovement/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.
This icon creates a new movement block.
This icon represents the block within the program.
Detail window for the selected block. You may change the following parameters:•Drive Motors (A, B, C)•Direction•Steering (C and B working together)•Power (Speed)•Duration(How Long - How Far)•Next Action (Brake or Coast)
