Helping Hands: Testing How Much Weight a Hydraulic-Powered Robotic Arm Can Lift

Grade:

4

Teacher:

Harlene Recto

This project investigates how hydraulic pressure can be used to control movement and lift objects by building a simple robotic arm powered by water-filled syringes and tubing. By pressing the syringes, liquid pressure transfers force to move the arm’s joints and grip objects. The experiment tests how much weight the hydraulic robotic arm can lift, demonstrating real-world engineering concepts such as force, pressure, motion, and energy transfer.
