A Hydraulic Press Robotic Arm

Creating a hydraulic press arm can be driven by several motivations, often rooted in both practical and educational purposes. My decision to build a hydraulic press arm stems from a combination of engineering curiosity, the desire for hands-on experience, and the practical benefits such a device offers.

Supplies

Cardboard Cutouts

Hot Glue gun

syringes

metal wires

rubber tubes

cutter

scicors

scale

pencil

dead batteries

clamps

skewers

4 colorful glasses of water

Step 1:

First we will take 2 rectangular strips of 20cm by 4 cm and make hole at the end of cardboard piece ,insert a skewer and stick it using hot glue gun. This will be the base of our hydraulic arm.

Step 2:

We will use another 2 rectangular pieces of size 26 cm by 4 cm and attach them to the previous piece using skewers and secure them with smaller square pieces of size 2 cm by 2 cm and then with the hot glue gun

Step 3:

Then we will take pieces as shown in the above image. The smaller size will be of 4 cm, bigger side of 7cm and slanting side of 13 cm then we will secure it using smaller cardboard pieces and hot glue gun

Step 4:

Then we will attach our arm to the base which has the size of 8.5 cm by 8.5 cm and a big hole to fit cell in it.

Step 5:

Now we will take a syringe, attach it to the skewer using clamps and attach it to the arm as shown in the above image.

Step 6:

we will use the same process to attach the next syringe but in another position

Step 7:

next we will take cutouts as shown in the above image and attach them with the help of skewers and metal wires.This is our grabbing mechanism
