1. OVERVIEW
In this challenge, you will:
Define the challenge’s parameters
Design a robot that can address all of the parameters.
Develop a robot program that will meet challenge parameters.
Deploy the robot to simulation area to test operations.
This is the 4-D as it comes to life and works in the real world!!

2. PARAMETERS
Defined
National Hot Rod Association standards for track and car
1:24 scale – why does it work? What does it mean?

Racing Basics –
Must cross finish line to be eligible to win
First dragster to cross finish line without penalties wins.
All times will be recorded.
Single competitor is allows, competes against time.
Courtesy of Todd Edmands, 2007
Specifically robots –
One motor (at least) required. No less than 3 nor more than 4 wheels
Competition only between dragsters with same motor count.
Straight steering only – no veering off course.
Due to scale, car’s size can only be between 7.5” and 15”
Only one NXT module per car, program to be run from front panel

Robots
Designed
Remember to get wheel circumference measurements.
Use the single rotation method to calculate rotations to use to get to the end of the track.
Use straight front axles to keep ground track true.
Consider using only one motor to accomplish task.
Consider the use of a two block program for DragBot.
Your design does not have to be like either of those shown – you can allow your creativity to flow.

4. PROGRAMMING Developed
Use NXT-G graphical programming language,
or other program that can control NXTs.
Programs must contain a starting point, and at least one Block – Motor.
If using more than one NXT device (adding a sensor) be sure to include programming for it as well as a good reason it is included in the Challenge.
Be sure to save the program both to the NXT and to your computer as a backup, in case something happens!!

5. FINISHED BOT Deployed Dyanimicity is critical in this step.
Test … test … test … test … test
Document results after each test!
Detail what change you must make to get the
results you want.
Test again. Vary only one parameter at a time!
Document everything you do, see, or etc.
