I always wanted to do this project but in all the guides i always found that you need some kind of wood cutting skills and/or tools. So … I decided to make a simple hydraulic robot with cardboard, reinforce and hold by duct tape that anyone can do.
Duct tape not only is strong but also looks pretty cool; it gives the robot a cool metal like look and it holds everything together really good.

Signing UpStep 1: What you are going to need!
- Cardboard box (the harder the better, I used a pizza box but you can used any type because we are going to reinforced with the duct tape)
- Scotch Duct tape (I like the silver because the metal like look)
- 3 machine screws 3 inches in size with nuts
- 2 machine screws 1 ¼ inches in size with nuts
- A flat and square piece is wood ideally 12 inches by 12 inches for the base to attach the robot
FOR THE HYDRAULIC SYSTEM:
- 8 syringes (you can get them at any pharmacy without prescription just say you need the type that is use for cough medicine, you can’t put a needle on those. I got mines at CVS and Walgreens for free)
- 6 feet of clear tubing ¼ “x .170” (got mine at home depot for $3)
- Water
TOOLS:
- Scissor
- Ruler
- Pen
- Drill

1. Fill up one syringe all of the way
2. attach the tubing and push water through it to remove air
3. with the end of the tubing submerged, fill back up to 10ml
4. attach the other syringe. You now have a simple hydraulic system
For smaller than 10ml you may need to remove air from the tubing by utilizing the siphon principle
Hope this helps!
and did you any b.tech level projects?

As far as holding the syringes, the diameter of my tube happened to fit perfect the tip of my syringe, not to tight not to loose. If this is not your case you can just use some hot glue gun.
good luck with your science fair.
my friend and i r doing this for our science fair and we are sorta confused about the way the tubes are set up.
thanks

there is not exact measurements for these pieces because the thickness of the cardboard and the amount of layers of tape is a variable thats is different to each person.
The best way to go is to measure and make this pieces as you go to make sure they fit right.
but its a reallly cool and time passing activity thanks.
