**Project:** Building a Hydraulic Robotic Arm
**Key Components:**
1. **Frame:** Cardboard pieces (30cm, 20cm, and stand) assembled with toothpicks and glue.
2. **Hydraulic System:** 10ml syringes, nylon cable ties, and toothpicks to create movable joints.
3. **Control Section:** Metal rods, ice cream sticks, levers, and cardboard to control the arm's movements.
4. **Platform:** Cardboard base with a pencil battery holder.
**Assembly Steps:**
1. Assemble the frame and stand.
2. Create the hydraulic system for the arm's joints.
3. Build the control section with levers and metal rods.
4. Connect the hydraulic system to the control section.
5. Attach the arm to the platform.
**Outcome:** A functional hydraulic robotic arm that can be controlled using the custom-built control section, demonstrating basic robotic and hydraulic principles.
Here are the key facts extracted from the text, numbered and in short sentences, excluding opinions:
**Materials Used**
1. Cardboard is used as the primary material for the robotic arm.
2. Toothpicks are used for joint connections.
3. Nylon cable ties are used for securing parts.
4. Metal rods (aluminum or iron) are used for the control section.
5. Ice cream sticks are used for the control levers.
6. Syringes (10ml) are used for the hydraulic system.
7. Glue is used for bonding parts.
8. Pencil batteries are used for the platform.
9. Small tubes (from sketch pens) are used for coloring water.
10. Water is used in the hydraulic system.
**Dimensions and Measurements**
11. Cardboard pieces are cut to 30cm x 4cm and 20cm x 4cm.
12. A 7cm gap is left between toothpicks on the 30cm pieces.
13. A gap for a 10ml syringe is created between cardboard pieces.
**Steps and Assembly**
14. Two 30cm cardboard pieces are connected with toothpicks.
15. Two 20cm cardboard pieces are used for the arm's end sections.
16. A stand is created using similar cardboard pieces.
17. Nylon cable ties are used to connect the syringe to the arm.
18. Metal rods are bent and used for the control section.
19. Levers are created using ice cream sticks and cardboard.
20. Holes are made for inserting batteries and metal strings.
**Project Requirements**
21. A total of 8 syringes are needed for the project.
22. Four levers are created for the control section.
23. Four metal rods are used for connecting the levers to the base.
**Functionality**
24. The robotic arm operates using hydraulic pressure from syringes.
25. Moving one syringe's plunger affects the movement of another.
