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.
