REPORT
OBJECTIVE
The objective of this project is to make a mousetrap racer which
travels and stays in a designated area. The objective emphasizes
on accuracy of the racer to stop after a constant distance is
covered. The project will utilize potential energy in form of
torsional energy in the wound spring of a mousetrap then
convert it to kinetic energy in the wheel axle until friction
causes it to stop. The experiment measures the accuracy of our
racer in a given angle of release therefore its accuracy.
While varying the degree of wounding the project can also go
on to investigate effect of change in mousetrap lever arm to
distance travelled by the racer. The degree of lever arm is
changed then racer distance is measured, this is then compared
4. to a bigger degree of lever arm release increasing the degrees
constantly then comparing it to distance moved by the racer.
This will give an indication of the relationship between lever
arm degree and energy output.
DESIGN CRITERIA AND BACKGROUND
The design used is meant to be simple and stable at the same
time. In some designs a piece of rod was added to the link
between mousetrap and wheel axle, this provided much power to
the racer than in our model. Our objective was however not for
power but for accuracy which the rod would not improve on.
This design utilizes materials used to create an accurate racer.
The materials chosen had a specific reason as to why. I chose a
wooden wheel rather than using a lighter CD because wood will
offer more traction as opposed to plastic. Traction is important
for it to move especially on tile floor. To ensure constant
distance travelled by the racer I used a fishing line which is
stronger than a simple string, the distance travelled will also be
constant therefore accurate because during winding only a
specific length of the line can be wound therefore making
distance travelled to be same and accurate.
The constrain realized was that wind continuous winding the
mousetrap losses some of its potential energy stored in the
spring so with time the distance travelled will lessen therefore
making it less accurate. The general principle used in this
project is minimizing weight and creating stable racer. This is
proven by the removal of the elongated lever arm while at the
same time creating a balance between the need to reduce weight
and need to increase stability. This made us come to the
conclusion that as much as CDs reduce weight the need for
stability provided by wooden wheels is far important. The team
also tried to increase friction by using wooden wheels instead of
CDs so as to increase traction creating movement of the racer.
Previously there were three models which were not
implemented. The first model was made of CDs in all wheels.
5. This model was not working well because the wheels offered
little friction, it just skidded over the floor. CDs were also not
stable they would move sideways a lot, the problem was solved
by using wooden wheels. The second model only the back
wheels were wooden the front had CDs. This model was aimed
at providing both stability (wooden wheels) and lighter weight/
more speed (CDs). However on the actual model was clumsier
than the one originally made of only CDs. The third model had
only wooden dowels in all axles which resulted in a relatively
slower racer, when this was changed to a metal rod which was
slimmer the racer moved faster. This was aimed at reducing
friction during its rolling; the small circumference spun by the
string also propels the racer a much greater distance with small
amounts of energy.
DESIGN
This was the team’s initial sketch on a piece of paper. The
side view illustrates what the racer will look like as it is racing.
It has direction of the tires as a result of the snapping of the
mousetrap.

Design Project 2: Mouse Trap Powered Vehicle
*While the idea of a mousetrap racer is of unknown origin, the
format of this specific assignment is adapted from an
assignment by Mukul Talaty, PhD.OBJECTIVE
Your goal is to design a vehicle that can travel independently
(once you spring the trap) and complete the following tasks:
7. (1) Travel as far as possible (maximum distance) on a smooth,
mostly level tile floor (like that of our classroom)
(2) Choose ONE of the following tasks:
a. Successfully pull a load a minimum distance (i.e., design for
power)
b. Successfully travel to and stay in a designated area (i.e.,
design for accuracy)
You will get to choose on which one of the last two objectives
you will be evaluated, but you must make that choice before
testing. Grading
Grading will be based on the following criteria:
1. Performance: did your design achieve the requirements stated
above. (bonus points for best in class)
GRADE PERCENTAGE: 35% + bonus points
2. Written and oral (in-class presentation) – details below
GRADE PERCENTAGE: 65%
a. Engineering drawings in SolidWorks and/or AutoCAD
GRADE PERCENTAGE: 10% (part of report grade) The project
will be done in groups of 3 or 4 (5 groups total). MATERIALS
Your group will be given one (1) mouse trap. You must use the
mousetrap you are given – you can’t go out and buy a better
one. If you ruin your mousetrap, you must buy a replacement
from me for 10% of the performance grade. (=3.5% of total
grade).
In addition, your group gets to choose 10 items from the
following list. Certain items can be ‘doubled’ (e.g., you may
buy two pairs of wooden wheels) but they will each count as an
item. PARTS LIST
1. 12”x 3” x 3/32” sheet of Basswood (or similar) wood
2. 8½” x11” piece of corrugated cardboard
3. 2 blank audio CDs (you may double up on this item, but it
will count as 2 of 10)
4. 2 wooden wheels (you may double up on this item, but it will
count as 2 of 10)
5. masking or duct tape 2 – 6” pieces
6. 2’ piece of string
8. 7. 2’ piece of fishing line
8. 12” length of 3/16”steel rod
9. 12” length of 1/8” steel rod
10. 12” length of 1/8” wooden dowel
11. 2 wooden pencils
12. 2 Popsicle sticks (you may double up on this item, but it
will count as 2 of 10)
13. 4 small washers (you may double up on this item, but it will
count as 2 of 10)
14. 6 paper clips (large)
15. 2 straws
16. 2 “zip” ties
17. 4 eye hooks (you may double up on this item, but it will
count as 2 of 10)
18. A “small” custom part that you may print on the 3d printer.
Specifications of this part are somewhat flexible and subject to
the instructor’s approval and the limitations of the MakerBot
printer (model: Replicator 2)
In addition to the parts above, you may use all the hot melt glue
you want, but you cannot fabricate parts out of hot glue! It is
only to be used as an adhesive. REQUIREMENTS
1. You are allowed ONLY what materials you select from those
that are listed above. Once you choose materials, you cannot
change your selections.
2. The vehicle must be built using only the tools in our lab
(*exceptions to this are possible and will be considered on an
individual basis, subject to my discretion)
3. You are allowed hot glue only to bond pieces together, but
not to fabricate any sort of part or material for any use other
than to fasten. Coincidental function, other than fastening, is
allowed so long as the fastening is the primary purpose and that
purpose is clearly explained.
4. All fabrication will be done during class time and in our lab.
(In other words: no, you can’t take it home with you and build it
with your friends.) It is permissible to meet outside of class
time to work on your design, the report, the presentation, etc.
9. 5. You should have fun doing this project. However, I will hold
you to professional standards of behavior:
a. You must follow proper laboratory safety rules, including
proper dress (especially footwear) in the lab/shop room.
b. You will be expected to behave in a safe and professional
manner while constructing your racer: e.g., tools should be used
in a safe manner, no poking your groupmates with sharp things,
no profanity.
c. You are expected to behave honorably: do not tamper with
any other group’s design. DUE DATES
1. Vehicles will be due at the end of class (10AM)
WEDNESDAY, APRIL 27, 2016. The last class (Friday, April
29) will be used to run the cars through the specified objectives.
2. Presentations will be given to the entire class and final
reports will be due at our scheduled final exam time, 8:30 AM
MONDAY MAY 2. The instructor will provide donuts.
REPORTING REQUIREMENTS
The written report (HINT: this is a DESIGN PROJECT)
1. Objective (more than “We have to build a car for this
project…”) 2. Design criteria, material constraints 3.
Background section:
a. Do a little research on mousetrap racers. Describe them
(pictures are fine). How do they usually get power from a
mousetrap? Are there several different ‘basic’ methods or does
everyone do this the same way?
b. Give me an indication of how your group is approaching this
project. What is your “guiding principle” that you hope will
lead you to glory? [for example: minimize weight, maximize
length, minimize friction, maximize energy recovery, etc.
4. A description of the alternate solutions YOUR GROUP came
up with (at least 3 total) including drawings (can be hand
sketches – but should clearly show the interesting features of
each alternate design) and why you ultimately rejected them.
a. These should be ‘reasonable’ – suggesting that you thought
about making it out of titanium and carbon fiber composite, but
10. rejected this because none of the items on the parts list are
made of titanium or carbon fiber is not a reasonable alternative
solution.
5. A detailed description of the final design – describing
specifically why you thought this design was the best. What
were the tradeoffs with the other designs? This must include
both
AutoCAD and SolidWorks drawings
a. NOTE: you can include drawings of subassemblies in one
program and the completed design in the other program; that is,
you should not put in the same drawing drawn with two
different programs.
6. Results of any preliminary testing you were able to perform
7. If you did testing that led to design changes, what the
changes were and how you arrived at these changes?
8. PARTICIPATION: I would like a section detailing each
group members’ participation in the project: “Bob was
responsible for the drawings in SolidWorks; Joe created the
PowerPoint presentation, Mary was the lead builder of our
racer.” If someone was absent for a significant part of the build,
this should be reported here.
PLEASE use the outline/guidelines for writing a report that we
have (hopefully) been using all semester long.
The Oral Presentation
The salient (important) points of your design process and final
design should be presented in a 10-15 minute slide presentation,
followed by 5 minutes for questions by the class.
1. All group members must participate in the final
presentations. In other words, everyone has to talk.
This is not just the instructor being cruel, this is to help you
overcome your anxiety about talking in front of people. This
class is the least intimidating place you will ever present; take
advantage of the opportunity.
2. The presentation should be professional, succinct, and hit the
major highlights of the project (you may choose which of the
11. above sections/steps to include/not include).
3. Your presentation must be between 10-15 minutes in length
(Practice it! Going over-time will count against the score in this
section). There will be 5 or so minutes for questions directly
following the talk (while the next group sets up).
4. Use slides: use presentation software that can be presented in
class from the instructors’ PC (I strongly suggest Microsoft
PowerPoint as I’m sure that’s available and I can help if there
are any technical difficulties, but if you insist on using a Mac
and some other software, YOU are responsible for making sure
it’s going to work.)
The group that performs the best in each category will receive 5
bonus points (i.e. 15 bonus points are up for grabs and up to 3
groups can win, barring any ties).
