Here’s a link to a rbr build plan
•Google Rubber Band Car and this is one of the links:


Materials needed:

• You need to bring to school these recyclables:
• A racer car chassis – a soft drink bottle, a milk carton/container (obviously thoroughly washed).
• Plus four bottle caps, or old cds, or similar. Plus anything else you may need which the school does not supply.

•A racetrack
•Rubber bands
•Paddle pop sticks
•Straws
•Skewers
•Masking tape
•The tools needed:

•**The YouTubes are not linked for student use, as they are YouTubes and can only currently be viewed on the projector screen**


The plan:

Week 1 – 2 Look at the YouTubes to get an idea what this is about.

Research the type of racer you intend to build.

Week 2 – 5 start designing and then when approved, build and racer.  Try another rbr build, if necessary.  Do your folio work.

Weeks 6 – 7 Complete your design folio.


Folio work:

•In Powerpoint, create your design folio.
•Start with Part 1 – My first rbr
•(There will be a Part 2 – later on, when you create a more refined racer).
•The title slide is Rubber Band Racer and your name.

•Next copy in some researched images of possible racer. There should be at least six images.

Link here for the Folio instructions.


Build and race the Rbr:

•Start assembling.
•Using the racetrack, test it.
•Make any adjustments.
•Race it against another students Rbr.
•Complete your folio evaluation of how it all went.

 

RBR Stage 2 - Build a Laser Cut and etched RBR, then race it.

1/. The RBR model is supplied (so you do not have to learn the software and design one. You will be making one out of mdf.

2/. Though you need to briefly research a design for your racer's main chassis.

You will be looking for an image, that you can modify if needed in Photoshop and using Illustrator, Place that image on the chassis top. See instructions in 5/. below.

4/. Image research instructions.

Google - Google Images, black outline images. Here are some ideas:

5/. You will need to download the rbr file from this resource and save it in your rbr file on your U drive.

The file looks like this when opened.

6/. Open the file in Illustrator and using the menu command File/Place, place the image onto the chassis of your rbr.

You most probably will have to resize the image to fit within the chassis. To do this hold the shift key and using the mouse pull the image back into the chassis to fit.

The final file should now look like this:

7/. Finally email your file to your teacher to include in a laser cut master template.
8/. When it is laser cut, you need to glue on the front, back and sides.
9/. You will need to place dowelling across the two axle holes and then glue the wheels on.

10/. Then affix the rubber band to the front axle and a pin to hold it at the rear.

11/. Once all done, race your rbr. Distance is the important part. Speed is not as important.
