**Project:** Building a Hydraulic Robotic Arm
**Materials:** Cardboard, toothpicks, syringes, nylon cable ties, metal rods, ice cream sticks, glue, etc.
**Summary of Steps:**
1. **Frame Creation**: Build the robotic arm's frame using cardboard and toothpicks.
2. **Syringe Mechanism**: Attach syringes to the frame using nylon cable ties, enabling hydraulic movement.
3. **Stand and Platform**: Create a stand and platform for the robotic arm.
4. **Hand (Gripper) Mechanism**: Design and attach a gripper to the arm's end.
5. **Control Section**: Develop a control system using metal rods, levers, and ice cream sticks.
6. **Final Assembly**: Connect all components, including hoses to syringes.
**Outcome:** A functional hydraulic robotic arm that can move and grip objects, demonstrating basic robotics and hydraulic pressure principles.
Here are the key facts extracted from the text, numbered and in short sentences, excluding opinions:
**Materials and Preparation**
1. The project requires a piece of cardboard, initially marked 30cm in length and 4cm in width.
2. Two pieces of 30cm and two pieces of 20cm cardboard are cut out.
3. Toothpicks are used for assembly.
4. A 10ml syringe is used, with a hole made in its plunger.
5. Nylon cable ties are utilized.
6. Metal rods (thin, made of iron or aluminum) are used for control.
7. Ice cream sticks are used for the control section.
8. A pencil battery is used for the platform.
9. Cardboard is used to increase thickness and strength in various parts.
10. Small tubes (from sketch pens) are used to fill syringes with colored water.
**Assembly Steps**
11. The 30cm cardboard pieces are connected with toothpicks, 7cm apart.
12. A gap is created to fit a 10ml syringe, maintained using glue.
13. The 20cm pieces are attached to the sides with toothpicks and glue.
14. Small cardboard pieces are used to facilitate smooth movement.
15. The stand is created using similar cardboard and toothpick methods.
16. The syringe with a hole is attached to the robotic arm using a toothpick and nylon cable tie.
17. The robotic arm's hand is made from bent cardboard pieces with a grip mechanism.
18. Metal rods are bent and attached to control the arm's movement.
**Control and Platform**
19. A platform is made by sticking two cardboard pieces together for thickness.
20. A hole is made in the platform to fit a pencil battery.
21. The battery is inserted and secured with glue.
22. Ice cream sticks with cardboard spacers are used for the control mechanism.
23. Holes are made in the ice cream sticks for metal string passage.
24. A lever is created using cardboard and ice cream sticks for control.
25. Metal strings are passed through the holes to connect the control section.
**Final Assembly and Testing**
26. Eight syringes are filled with colored water using small tubes.
27. The control section is connected to the syringes using hoses.
28. The final assembly includes connecting all hoses to respective syringes.
29. The project is tested to demonstrate its working mechanism.
