Introduction: Lego Mousetrap Car
Do you need to make a Mousetrap car for science class? Do you have some Lego's around the house that aren't being used? Do you have 10 minutes of free time?
Well this simple design will leave you with a quick accelerating, compact mousetrap car that will beat the competition. With this design I ended up getting 1st place in acceleration, and 6th in distance.
Step 1: Parts You Need
Parts you will need:
(x4) Small Lego Technic tires
(x2) Skinny gray spacers
(x2) Fat gray spacers
(x2) 1x16 bricks with holes in them (the yellow ones in the picture)
(x2) 1x6 plates
(x2) 1x8 plates
(x1) 2x6 plate
(x2) 1x4 plates
(x4) 4x6 plates
(x1) 10 long axle (about how many brick dots long it is)
(x1) 8 long axle
(x1) Red K'nex piece
(x1) Mouse Trap (duh...)
Step 2: Layout the Base Pieces
Step 3: Add Front Support
Attach two 4x6 base plates onto the top and bottom of what will be the front.
Step 4: Attach More Support!
Add the two 1x8 base plates into the top of the vehicle.
Step 5: More Support...
Flip the car over and add the two 1x6 base plates as well as the 2x6 base plate.
Step 6: More Pieces to Add
Flip it back over and add the two 1x4 base plates to the top rear end of the car.
Step 7: Final Support... Finally!
Flip the car over and add the final two 4x6 base plates onto the bottom of the vehicle.
Step 8: Add the Axles
Place the 8 long axle in the front of the car, and the 10 long axle in the rear.
Step 9: Add Spacers
Put the two larger spacers on the rear axle, and the two smaller on the front. Make sure to leave some space so that the axles can rotate easily.
Step 10: Wheels!
Add the wheels!
Step 11: Prepare the Mousetrap
For this step you need to attach the red K'nex on to part of the mouse trap (duct tape works well). Then you need to tie your fishing string on the tip of the red K'nex. Place the mouse trap on the vehicle and line it up with the front and sides.
Step 12: Attach the Trap
Get a piece of duct tape and cut if in half, length wise. Attach the trap on the back over the V logo, and wrap it to the bottom. Then lift up the red K'nex part and release mechanism and attach a piece there and secure it underneath.
Step 13: FIN!
Oh, and make sure to wrap it the right way, or your car will go backwards...
Step 14: In Conlcusion!
