FINAL BLOG POST

Outcomes

1. MATERIALS
-MOUSE TRAP
-2 SREWS
-HOT CLUE
-COPPER WIRE FOR ACELS 
-HEMP STRING
-ALTERED MOUSE TRAP WIRE
-ACRYLIC WHEELS * 8
-4 SCREW EYE SCREWS
-WOOD

WE USED A PEICE OF WOOD, AND LASER ETCHED THE WOOD AND CUT OUT SHAPES TO MAKE THE CAR LIGHTER. WE THEN LASER ETCHED ACRYLIC FOR OUR WHEELS, WHICH WERE 5 CM DIAMETER AND 8.5CM DIAMETER. WE THEN WENT TO THE SHOP AND RECREATED THE ARM OF THE MOUSE TRAP. WE MADE OUR NEW ARM OF THE MOUSE TRAP 27.5 CM LONG INSTEAD OF BEING 4.25 CM LONG. WE THEN WENT BACK TO THE SHOP TO DRILL 2 HOLES IN THE MOUSE TRAP AND THE WOODEN CAR SO WE COULD FIT THE BOLT THROUGH. EVENTUALLY WE FOUND SCREW EYES THEN USE THE METAL COPPER RODE THEN USED THE EYES TO HOLD THE COPPER WIRE. WE THEN USED LITTLE BIT OF TAP FOR TO TRANSFER THE MECHANICAL ENERGY FROM THE MOUSE TRAP TO THE WHEELS. 

2.Identify, select and use elements and principles of design in project activities

WE MAINLY WERE GOING FOR WEIGHT, WE DIDNT WANT MUCH WEIGHT ON THE CAR DUE TO THE RECREATION OF OUR MOUSE TRAP. SO WE ALSO DID SO BY CUTTING OUT SHAPES OUTA THE WOOD TO MAKE IT LIGHTER. WE ALSO USED ACRYLIC WHEELS INSTEAD OF WOODEN WHEELS TO CUT BACK ON WEIGHT. 

3. MOUSE TRAP 1.0 
WE USED CHLOROPLAST FOR OUR BODY OF THE CAR. THE REASON WHY WE LEFT THAT IDEA WAS BECAUSE THE ACELS BETWEEN THE RIBS IN THE CHLOROPLAST WERE UNEVEN AND WOULD MAKE THE CAR TURN TO THE RIGHT. 

MOUSE TRAP 2.0
WE USED WOOD INSTEAD OF THE CHLOROPLAST. THIS IS WHEN THE USE OF THE SCREW EYES CAME IN. WE PUT THEM IN TO SUPP[ORT THE ACEL. EVEN WITH THIS IT STILL TURNED TO THE RIGHT. BUT WE DISCOVERED WHY. IT IS BECAUSE THE SCREW EYES WERE UNEVEN BY A MILLIMETRE OR 2. WHICH CAUSED THE SLIGHT TURN. SO WE STRAIGHTENED OUT THIS THEN IT WAS NOT AS CRICKED.

4. Produce and present a portfolio-ready drawing, image, model, rendering or animation

MODEL 1.0
7.Demonstrate basic competencies: An honest evaluation of how well your team

- demonstrated fundamental skills to:
- communicated
- demonstrated personal management skills
- demonstrated teamwork skills
- demonstrated positive attitudes and behaviours
- were responsible
- were adaptable
- work safely

- communicated
GIBSON -

- demonstrated personal management skills  = 8/10
- demonstrated teamwork skills  = 9.95/10
- demonstrated positive attitudes and behaviours  = 8/10
- were responsible  =4/10
- were adaptable    =5/10
- work safely   =10/10

AARON - communicated
- demonstrated personal management skills.  =8/10
- demonstrated teamwork skills  =8/10
- demonstrated positive attitudes and behaviours  =7.5/10
- were responsible  =9/10
- were adaptable  =10/10
- work safely  =10/10



WE DID NOT DO THE 3D ST=KTCH UP BECAUSE THE PROGRAM FROOZ AND THERE WAS TO MUCH WORK DONE THAT WASN SAVED TO REDO IN SUCH LITTLE TIMES

Reality Check!!

Constraints 

1) the chloroplast was to flimsy, thus causing us to hot glue/tape metal rod to the bottom.
2) the mouse trap would not give enough power, hence us modifying the mouse trap.
3) the mouse trap was to powerful, to which we bolted it to the chloroplast.
4) where the clamp was to big, which cause it to snap to the ground which cause the car to slow down.
5)it looks crappy, but its not all about looks...
6) the wheel were very uneven and crooked, to wear we resolved this problem by gluing the wheels to the axels.

New Solutions

1) our car wont really move. solution- were gonna take some weight off the car plus were gonna put some special lube to lube up the axels 
2) When we screwed the mouse trap to the cholorplast, we screwed up on the alignment of the holes. to which it started to buckle. Our solution that was, we glued and duck taped a metal copper rode to the bottom of the cholorplast, to help with stability of the product.

Progress report!

This is what have completed in our last few classes. We have remade the snap part of the trap to make it a lot longer. the only thing that we are debating on changing is the tires

Day 9 - of making our mouse trap car

Today we are finishing up our 3D design in google sketch up. We will be posting the picture of the google sketch up soon. Next we will be moving on to scavenging  matterials needed. As our prototype of due this friday. We will post pictures of that also later on this week.

LEARNING FROM OTHERS

LEARNING FROM OTHERS

Mouse Trap Car- 
 Introduction: Making a mousetrap car is a mechanical engineering challenge often used as a competition for students from 5th grade up to the second year college.
A mousetrap powered car is a vehicle that uses a mouse trap for a motor and a string to transmit force. In this method one end of a string is attached or tied to the arm on the mousetrap and the other end of the string is wound around an axle.
By winding the string around the axle the mouse trap's spring is stretched and now you have your stored energy. As the mousetrap car is released the mouse trap pulls the string off of the axle causing the wheels to turn and off the vehicle goes.
Mouse_Trap_Car
Some students may prefer to cut all the woods themselves and design their own car; however, most students and teachers prefer to get all the parts in a kit and make changes as they need.
With this project students can explore:
  • A simple propulsion method
  • Basic gluing/ craft techniques and design concepts
  • Concept of stored energy
Items Needed:
Mousetrap Car Kits usually come with parts, cut to size and ready to use. The picture in the right shows the materials you usually find in a mousetrap car kit from MiniScience. Kit includes at least 16 wooden parts cut to size in addition to the mousetrap, string, rubber bands and 8 brass eyelets.
Materials Checklist:
Before using the kit please verify the content with the parts in this picture.
In addition to the kit parts you will need:
  • White glue or wood glue
  • Grip Pins
  • Sand Paper (Medium Grit)
  • Tape++
  • Latex Paint
