Hydranoid is a competition of Techfest, IIT Bombay which is Asia's largest science and technology festival. The task is to design a bot which can push off blocks from the top of buildings (without touching the building) using hydraulic pressure mechanism.

5. 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.

6. Step 2: Planning and Cutting

7. After choosing the model that we would use, cut the pieces (not much criterion measurements) as shown in picture.

8. Step 3: Cutting and Mounting Arm

11. Step 4: Cutting and Mounting Claw

12. 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.

13. Step 5: Cutting and Mounting Base

15. •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

16. Step 6: Putting it all together

18. 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.

19. 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.

20. Step 8: Final Result

21. Syringe Actuated Mechanical Arm
