how to make a hydraulic arm model show step by step pictures
Lets make a simple hydraulic arm! I designed this simple arm that's powered using syringes as hydraulics.
I've also made a video so make sure to check that out!
What I used-
Platform- I used a round table coaster
Rotating base- I used a tin lid
Arm- 2 large lolly sticks and 4 standard sized lolly stcks
Hydraulics- 6 1ml syringes I acquired from amazon.com
Electro magnet, battery and switch - I got mine from the local electronics store
Nails
After shave bottle lid- used to heighten the arm from the base
Rubber bands
1 Pin
4 Pearler beads
Hot glue!
For the platform I used a circular table coaster as it was easy to punch pins/ nails in to. Th rotating base of the arm is made from a tin lid which I drilled a hole in the centre. I used a pin and a perler bead (perler bead used as a spacer) to secure the base to the platform allowing it to rotate.
