HYDRANOID

Hydraulic system works on pressure differences

The resultant output force can be used for

movements of simple parts as shown in

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.

Step 2: Planning and Cutting

After choosing the model that we would use, cut

the pieces (not much criterion measurements) as

shown in picture.

Step 3: Cutting and Mounting Arm

Step 4: Cutting and Mounting Claw

The gripper is designed to move just one piece. It was more simple. The "finger" was

pasted fixed and mobile was seated on a shaft made with a piece of wooden stick that

had a piece of cardboard cut in a circle glued on top so as not to leave the place.

Step 5: Cutting and Mounting Base

• The base is made from two pieces of cardboard in order to support

arm and accommodate syringes in the same set

• The movable part has two holes: one in the center (to be able to

rotate the base) and another at the end (to link the syringe and allow

movement)

• The syringe is attached to another piece of cardboard to keep the

same level of mobile base

• After verifying the limits of movement, fix the syringe with the clamps

Step 6: Putting it all together

After creating the arm, claw and

base pieces are put together to

test out the movements and

check if everything is working

properly. Once assembled, it is

found that the syringe clamp is

not well positioned. A piece of

cardboard is cut to attach the

syringe to another position, as

shown in figure.

Step 7: Filling the Syringe

Choose four colors to

color the water and fill the

syringes. Fill the hose

and then put a syringe

(without air inside - close)

on one end. Fill another

syringe (not filling all) and

put the other end. Check

the operation.
