Hi, Welcome to my instructable !
In this instructable i will show you how to build a Robot Racer !
The robot racer is a fast, fun, easy-to-build elastic band car.
The car uses recycled tubes, bottle tops and even recycled elastic bands.
If you skim through this instructable and like it, it is entered in the Klutz Competition and i really need your vote !!
Thanks and i hope you enjoy the instructable !
Step 1: Materials and Tools
- 1 Cardboard tube
- 1 Elastic band
- 4 Bottle Tops
- 1 Kebab/Barbecue skewer
- Craft knife / Scissors
- Dremel (only if tube is really thick)
- Glue Gun
The tube can be a recycled toilet roll tube, my tube originally held a roll of kitchen foil
Post-Men drop elastic bands all the time when their doing their rounds, have a look on the pavement/sidewalk when you next go out
The bottle tops need to be larger than the tube so look on milk bottles or cleaning products !
I got my kebab skewer from my kitchen but any thin rod will do !
Step 2: Cutting the tube
You don't want it to be huge because then it wont go very far !
My tube is 18cm / 7.1 inches long.
Once you have decided on the length of your Robot Racer, mark it out on the tube using a pencil and cut it using either a craft knife or scissors depending on the thickness
Step 3: Drilling the holes
If you have a thin tube you can use the rod itself to poke the holes. My tube was quite thick so i had to drill the holes.
If you are going to drill you will need to find a drill bit that is slightly larger (1mm larger is good) than the stick you are going to use.
Making the hole slightly larger means there will be less friction on the rod and the car will go further. !
Use a ruler to make sure the holes are in line.
