EASY TO MAKE: Hydraulic Arm

For the research behind my design: https://sites.google.com/site/hydraulicarm/

Grade 10 tech class project:
make a hydraulic powered arm which can turn 90 degrees, as well as pick up and drop 3 film canisters.
Materials used were corrugated plastic, wooden dowels, 6 plastic syringes and 5 feet of plastic tubes.

dude, this didn't help me at all, i need to know how to make one, not how to watch you show off with yours

@kevin201821 So i suppose you didn't take the time to follow the link in the description, or read other people's comments and the advice I gave them. I hope you have a fun time building yours using your own creativity and ingenuity, not someone else's step by step instructions.

how are you rotating its base??????... (need an urgent reply) thanks for posting it as helped me lot in my project.

@saniasafdar glad it helped!

We used hydraulics to push a small "neck" that attaches the wooden base to the bottom of the hydraulic arm. the neck pivots on an axle (we made it out of wood), and isn't actually glued to either the wooden base or bottom of the hydraulic arm. remember it has to rotate freely.

If you go to the link in the description, and then go to "schematics" the image might help you understand better. Good Luck :)

1. We attached two syringes together with a plastic tube and filled it with water.

2. Then we placed one so that, when the syringe's top extends (by pushing on the other syringe) it pushes on the neck attaching the base of the hydraulic arm to the fixed wooden base.

3. I recommend viewing the schematics i posted in the description, it'll help with the explanation.

@soccerjudo10 ty. but i have no idea how to lift a 4x4x5cm box with no lift thingy that your cylinder has. i know you have to use a claw but we only have 6 syringes.
