Mousetrap Car Competition


Overview

Overview

  • What is a mousetrap car?

  • How it works

  • The competition

    • Design specifications

    • Rules

    • Scoring

    • Extra credit


Objective

Objective

  • Design and construct a mousetrap car

  • Competition

    • Which design travels furthest?


What is a mousetrap car

What is a mousetrap car?

  • A vehicle powered only by a standard mousetrap


How does it work

How does it work?

  • String wrapped

  • around axle

  • Lever arm pulls string; string rotates drive-axle;

  • drive-axle moves wheels to create forward motion


Materials

Materials

  • Robolab kit

  • Mousetrap

  • Kevlar string

  • Tape

Ebaumsworld


Procedure

Procedure

  • Brainstorm designs using Lego parts

  • Sketch design

  • Construct


Design specifications

Design Specifications

  • Sketch must be drawn and initialed by TA before construction

  • Minimum of 1 wheel

    • Projectile designs not permitted

  • Mousetrap may be attached with tape

  • Mousetrap is only source of power

  • Mousetrap may not be physically altered


Competition

Competition

  • Load and position vehicle at starting line

  • Release mousetrap vehicle

  • Each team will have up to 3 trials (time permitting)

  • Modifications between trials permitted


Rules

Rules

  • Start

    • Pushing not allowed

  • Vehicle must not be touched once started

  • Linear distance traveled will be measured by TA

  • For collisions (wall, person) distance will be measured from start to point of impact


Credit

Credit

  • +10 points extra for greatest linear distance in section

    • Bonuses for other places as shown in the grading policy


Report

Report

  • Individual lab report required

    • Discuss advantages and disadvantages of your design


Closing

Closing

  • Have photo taken of your design

    • Required for lab report

  • Disassemble vehicle

    • Return complete Lego kit & mousetrap

    • Remove all tape from parts
