There are three main types of vehicles; long range, high speed, competition. The defining characteristic of the long range vehicle is it's large drive wheel. For the high speed vehicle its, you guessed it, it's high speed. As for the competition vehicle they must comply with guidelines most likely for school or Science Olympiad.
This Instructable will be for the designing and building of a mousetrap vehicle following the rules for Science Olympiad devision C for the 2010 - 2011 academic year.
Step 1: Design
*a writing utensil
However, if you want to design a vehicle that you will be proud to put your school's name on you will also need:
*a graphing utility
* micrometer(if you have a thing for sig figs?)
**a good foundation in mathematics
**Those who do not possess these skills, yet. Have no fear there are countless resources at your disposal. For example the internet, public libraries, and your teachers. The internet, your on it now. Public libraries, they are free and full of helpful underpaid knowledgeable city employees know as librarians. The other option is your teachers. Who would be enthralled to have a student or non-student ask for their help and guide you. That is if you don't owe them any work.
Here is the SciOly wiki on mousetrap vehicle, an indispensable resource.
After reading the rules, read them again. The last thing you want to hear is, after all your hard work, "your disqualified."
