  1. EG1003: Introduction to Engineering and Design Mousetrap Car Competition

  2. Overview • What is a mousetrap car? • How it works • The competition • Design specifications • Rules • Scoring • Extra credit

  3. Objective • Design and construct a mousetrap car • Competition • Which design travels furthest?

  4. What is a mousetrap car? • A vehicle powered only by a standard mousetrap

  5. How does it work? • String wrapped • around axle • Lever arm pulls string; string rotates drive-axle; • drive-axle moves wheels to create forward motion

  6. Materials • Robolab kit • Mousetrap • Kevlar string • Tape Ebaumsworld

  7. Procedure • Brainstorm designs using Lego parts • Sketch design • Construct

  8. 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

  9. 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

  10. 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

  11. Credit • +10 points extra for greatest linear distance in section • Bonuses for other places as shown in the grading policy

  12. Report • Individual lab report required • Discuss advantages and disadvantages of your design

  13. Closing • Have photo taken of your design • Required for lab report • Disassemble vehicle • Return complete Lego kit & mousetrap • Remove all tape from parts
