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.

Cardboard Cutouts

Hot Glue gun

syringes

metal wires

rubber tubes

cutter

scicors

scale

pencil

dead batteries

clamps

skewers

4 colorful glasses of water

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.

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

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

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.

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.

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

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
