Hydraulic power is used in machines like cranes and robots. These machines use water or liquid to help move things. My problem is to find out how hydraulic power can be used to move and lift objects using a robotic arm. I want to see how pushing water through tubes makes the arm move. This project helps me learn how real machines work.

First, I make the parts of the robotic arm using cardboard. I cut the cardboard and build the base and arm. Then I connect syringes with plastic tubes and fill them with water. I make sure there is no air in the tubes. I attach the syringes to the arm using tape and glue. When I push one syringe, the water moves and makes the arm move. I try lifting small objects and watch how the arm moves.

When I push the syringe slowly, the arm moves slowly. When I push harder, the arm moves more. The arm works best when there is only water in the tubes. If there is air, the arm does not move well. The robotic arm can lift small and light objects. This shows that water power helps move things.

This project shows that hydraulic power can be used to move and lift objects. Water moves through the tubes and transfers force. This is how machines like cranes and robots work. I learn that removing air from the tubes makes the arm work better. This project helps me understand how science is used in real life.

I learn about hydraulics from these websites:

Encyclopaedia Britannica – Hydraulics https://www.britannica.com/science/hydraulics

Britannica Kids – Hydraulics https://kids.britannica.com/kids/article/hydraulics/399505

HowStuffWorks – How Hydraulic Systems Work https://science.howstuffworks.com/transport/engines-equipment/hydraulic.htm

I would like to thank my parents/guardian for helping me with cutting cardboard and setting up materials safely. I also thank my teacher for explaining the science concepts and encouraging me to complete my project. I am thankful to everyone who supported me and helped me learn during this science fair project.
