Picture of Hydraulic Arm
This hydraulic arm was a homework for my daughter's school. The idea was to create a toy from recycled materials. Hope you enjoy.


Step 1: Materials

- Pieces of cardboard
- 8 syringes
- 1,5 meter hose (aquarium pump)
- 15  Plastic clamps
- 2 screws with 3 washers and 4 nuts
- 1 piece of wire (clothespin)
- 1 wooden stick
- Water, paint, glue, knife, ruler, etc..

I made a hydraulic crane with detachable parts and a bucket using all but popsicle sticks, cotton swabs,cardboard and hot glue ;that costed me around $2 and works quite good, tell me if you guys would like me to make a tutorial!!

i had something like this before. then i broke it with over pressurizing it.

so i might build this. becuses it doesnt need to be pumped up.

plese give us measurements
PeckLauros (author)  moosaahmed10 months ago

Hello . Unfortunately this is an old project and I missed the measures . Will depend on the size of syringes you buy.

what can it pick up in particular cause I have to do it in school
PeckLauros (author)  moosaahmed10 months ago

Some plush toys and some origami . The claw is not very strong . It was meant only to showcase the work of pistons in a didactic way .

I do not need the demensions to each part but just out of curiosity, (hope I don't get killed like the cat), what is the size of the whole project put together? I don't even need exact numbers an estimation would even be fine.
